EDITOR'S NOTE (FEB 19, 2018): Sherman Williams has changed the formula for the paint recommended in this article. We have not done any further retesting or searching for an alternative paint to recommend. Please DO NOT buy the Sherwin-Williams ProClassic Smooth Enamel Satin Extra White, # B20 W 51, which was recommended in the article as written in 2011. It is now too glossy.
Since 1080p home theater projectors have dropped below $1,000, the demand for inexpensive screens is bigger than ever. When you spend less than $1,000 on a projector, you don't want to spend big bucks on a screen to go with it. So for hobbyists with a creative, DIY bent, let's focus on how to paint the perfect screen for under $100. We will look for a good paint solution because it is easy, cheap, and it doesn't warp and ripple over time like fabric screens can do.
First, if we are going to build a great screen, we need a standard of perfection to compare it to. That, to us, is the Stewart Studiotek 100, a perfectly neutral 1.0 gain white screen that reflects back exactly what the projector puts out. It has absolutely no color bias, no gain, with a pure smooth finish that reflects the maximum amount of image detail. Since white paint will have a gain of about 1.0, the Studiotek 100 is a good benchmark against which to compare our results.
What about gray paints?
Many people are interested in gray screens and paints due to their increased black level. So we started our evaluation with the popular Behr Silver Screen formula. We painted a test board and mounted it in front of the Studiotek 100. Illuminating these two surfaces with a variety of test patterns and video clips revealed significant differences in contrast and color balance.
The one advantage the Behr Silver Screen had over the Studiotek 100 was black level, which is expected from gray paint--the darker the screen, the darker the black level. In scenes with a black background and white highlights such as rolling credits, the paint showed a higher contrast image and a much more solid black. The Behr Silver Screen is the perfect solution for people who watch rolling credits. Unfortunately, that's not what 99% of one's viewing subject matter consists of.
The Behr image was 27% dimmer than the Studiotek 100. That, in itself, is not a problem if you have a small enough screen or a bright enough projector. But the Behr Silver Screen kills color saturation, and it appears to reduce vibrancy in the warmer end of the spectrum. This should not be surprising. Imagine, what do you get when you mix gray with yellow? You get a grayish yellow. If you mix gray and blue you get a grayish blue. But the compromise of the yellow is more noticeable.
On the Behr gray paint, flesh tones looked horrible, appearing dirty or ash-colored in comparison to the Studiotek 100. Red and yellow color saturation is the most muted, and white highlights appear as subdued grays. Overall, the Behr Silver Screen paint does not deliver a balanced image. It certainly is not showing you what the projector is putting out. On its own, due to its increased black level, it may look fine if you don't have anything to compare it to, and the deep black creates an impressive sense of contrast under the right circumstances. But it is not a paint we would recommend for optimum home theater performance.
Gray screens were invented to compensate for the low contrast projectors of years past. But with today's high contrast models, we favor the use of white screens unless you have chronic uncontrolled ambient light. Since white paint should have a gain of about 1.0, the same as the Studiotek 100, we set out to see how close we could come to replicating the performance of the Studiotek 100 with white paint. Would it be possible to find a perfect replica?
Of course, there are paints out there that are specially designed for home theater. Goo Systems makes a great (and very popular) paint product. Previous testing with Goo showed that it is perfectly color balanced, and an impressive product. But for this project we wanted to keep total screen cost under $100, and Goo costs more than that. Other companies make paints they claim are formulated for home theater screens. But since they cost upwards of $200 a gallon, they already blew our target budget for a $100 screen. We limited our evaluation to white paints most people can find locally for under $20 per quart.
A Million Shades of White
If you go to your local paint store, you'll find an array of paint chips that represent different formulas of white. They have names like Polar Bear, Snow Fall, Swan Wing, Moon Rise, and so on. They all look white. But none of them are the perfectly neutral white that you want on a home theater screen. They each have a subtle color bias that will affect how your projected image looks. If the white has a bright, cold, crisp tone, it is because it is reflecting more blue light than is ideal. If you use this shade of white on your screen, flesh tones will look a bit cooler than the projector is putting out, while blue skies will be slightly oversaturated.
Conversely, warmer tone white paints look warmer because they are reflecting a bit more red and yellow relative to blue. They will give flesh tones a bit more warmth than normal, while reducing the brilliance of a blue sky or the fresh look of green grass.
The objective is to avoid these errors. So how do you get neutral white? In theory, the most neutral white in any paint vendor's product line should be the base white that exists before any pigment is added. So that's where we started.
The Search for the Perfect Paint
We started our search with the flat latex base white from both Behr and Valspar. To test them we painted sample boards and mounted them each in front of the Studiotek 100, and illuminated them with a projector. Between the two, the Behr imparted a more obvious color imbalance, biased toward blue. The Valspar was closer to replicating the color values of the Studiotek. It wasn't quite perfect, being a very tiny shade warmer than the screen. But it wasn't bad at all, and noticeably more neutral than the Behr. We decided to drop Behr from the running, and continue experimenting with various Valspar finishes.
Flat, glossy, or what?
As far as finishes go, conventional wisdom holds that flat latex is the best option for a home theater screen. This was not our experience. It is certainly true that any high gloss finish creates a bad glare that makes the picture unwatchable. But a flat or matte finish is almost as bad. It produces a dull image that does not have the contrast or color saturation of a professional projection screen. While the Valspar's Base 1 with no added pigment was reasonably solid in color balance, the Matte finish that we started with rendered an image that was unacceptably dull compared to the Studiotek 100. [BAN1]
Valspar comes in a variety of finishes that increase in sheen, including Matte, Eggshell, Satin, Semi-Gloss, and Glossy. Since the Matte was too dull, we moved on to Eggshell--better, but still a bit dull. Next we tried the Satin. This one looked quite acceptable--not perfect, but a very nice picture. Stepping up to the Semi-Gloss, we suddenly overshot the runway; the Semi-Gloss was way too shiny, creating a host of annoying hotspots and artifacts that made it useless.
So we thought...what would happen if we blended Satin with Semi-gloss? We blended Satin two-to-one with Semi-Gloss, and painted another test board. Nope, still too glossy. Satin was the best choice in the Valspar line.
Was the Valspar Base 1 Satin as good as it gets with paint? Its color balance was almost identical to the Studiotek, but ever so slightly warmer. Highlights were actually brighter on the paint than on the screen. Unfortunately, black levels were also a bit elevated. The picture was extremely similar, but it didn't quite have the snap that the Studiotek produced. Close, but no cigar.
The Search Continues...
Time to road test another brand. We went to the local Sherwin-Williams store. Based on our experience with the Valspar, we started with their version of Satin, which they call the Duration Satin Extra White. As with the Valspar, we used the base stock paint with no pigment added. After two coats on another sample board, we set it up against the Valspar, and put them both in front of the Studiotek 100.
Wow! Now we were cooking with gas. The Sherwin-Williams Duration Satin Extra White was an absolute dead ringer for the Studiotek 100 in terms of color balance, and oh so close in contrast and saturation. There was some subtle variance in its ability to hold black levels compared to the screen, but for the money, who would quibble? It was hard to believe that an inexpensive paint could produce such stunning results. There seemed to be no more room for improvement, so we thought we had our winner. [BAN2]
But we weren't done yet.
The Problem of Screen Resolution
One key advantage to the professional high resolution screens is that they have a perfectly smooth surface which enables them to reflect images with the optimum amount of detail. With 1080p projection, this is an important consideration. The problem with most painted surfaces is that you end up with brush strokes or mottling from the roller. The surface is not as smooth as a professional screen, and this will take a bit of edge off the sharpness of the image.
The only way to replicate the smoothness of a high quality screen is with a paint sprayer in the hands of someone who knows how to use it effectively. Most people don't have paint sprayers or the skill to use them. You can rent them for $60 a day, but you need to spend some time (and paint) practicing to get the results just right. Since our objective was to find the simplest and cheapest solution, we wanted to get the best results without going the paint sprayer route.
Back to Sherwin-Williams we went. Their staff had two suggestions. First, use a roller with the smallest, tightest nap you can find, since it will produce less mottling of the surface. Second, instead of the Duration, try the ProClassic Smooth Enamel Satin Finish. This product has a different surface tension that will cause it to settle into a smoother surface than the Duration. It is made for trimwork and doors, not walls.
We bought some of that, brought it back, and put two coats on another test board. Yep, it worked as advertised. The finish was indeed a bit smoother, with fewer obvious surface flaws than any of the previous paints.
Setting up the test board with the ProClassic Smooth Enamel Satin against the Studiotek 100, we discovered that we had not only arrived at our objective, but surpassed it. Color balance was dead on, just as with the Duration. But this paint actually delivered a slightly brighter image with deeper blacks. With a checkerboard test pattern, the black and white squares that fell on the test board were visibly higher in contrast than those that fell on the screen. A spot meter confirmed what we could already see--white highlights were brighter by about 10%, and blacks were blacker by about 10%.
This paint had a gain of about 1.1, with higher contrast than the Studiotek 100. But even more intriguing, the slightly smoother finish of the Enamel was doing its job. There was very little difference in 1080p image resolution. Practically speaking, most people looking at the two would say there was no difference at all.
Not the only perfect paint
Once we were satisfied with the particular Sherwin-Williams paint, we stopped evaluating other products. When we hold the test board with this paint up against the Studiotek, it virtually vanishes. So our objective of creating an outstanding reflective surface was met.
Having said this, we don't want to make any pronouncements about this one paint from Sherwin-Williams being the magic bullet above all others. It just happens to be the one we found that gave us outstanding image quality with perfect color balance. This one was relatively easy to find, so we assume there are plenty of paint options from other vendors that will produce similar results.
How does it compare to the Studiotek 130?
In addition to our Studiotek 100, we have a Studiotek 130 on hand. This is the screen material Stewart recommends for high performance home theater. Its modest gain gives the picture a noticeably improved luster and brightness that the Studiotek 100 does not have. Just for grins, we put our test board up against the Studiotek 130 to compare images.
The Studiotek 130 certainly produced the better image. Anyone putting in a high performance projection system would want the 130 over our paint solution. But for the money, the paint was holding its own remarkably well. Its highlights were not as brilliant, and the paint could not quite match the beautiful luster of the 130. But color balance was perfect. Overall, most viewers would be thoroughly impressed with what the paint could do. In terms of overall image quality in the average home theater environment, the paint fell a bit short of the Studiotek 130, but surpassed the 100.
Creating your Screen Masterpiece
Now that we have found an ideal paint, let's get down to the nuts and bolts of creating the screen. When you buy a professional screen, you not only get an ideal screen surface, but you get a solid black frame around the image as well. This adds greatly to the aesthetics of viewing movies and video. If all you want to do is paint a wall and project onto that wall, you can certainly do just that. But we are going for the gold here...for $100, we want to create a full replica of a professional projection screen, so it looks like that is what is mounted on your wall. Taking some time to create your screen masterpiece will pay off in much greater enjoyment for years. The basics are simple: [BAN1]
First, paint the wall outside the screen area
You might want to jump right in and paint the screen first. But that isn't a good idea. The objective is to end up with the illusion that you have a professional screen hanging on your wall. A key to achieving this is to paint the rest of the wall outside the screen area a darker color. Not only will this make the screen itself look like it is popping off the wall, but it will help reduce light reflections in the viewing room and give you a better home theater experience.
The reason you want to paint the rest of the wall first, before painting the screen area, is that you will be painting above and around the intended screen surface. You do not want to accidentally drip paint onto a finished screen surface.
For the rest of the wall, choose a color that is compatible with the décor. If this is a dedicated home theater room, you may want to use a medium to dark gray. If this is a multi-purpose room or living room, any low saturation color that complements the décor will work. Anything darker than white will create a pleasing contrast between the screen and the wall. The trade-off is that as you go darker, it improves the viewing space as a theater by cutting down light reflections that get bounced back onto the screen. But excessively dark wall treatments will make the room feel smaller and perhaps less comfortable for other uses. You need to sort out the right balance for your tastes.
When painting the rest of the wall, choose a flat, or matte, latex paint. This will reduce reflectivity, which is why it is not good for the screen itself. (By the way, if this is a dedicated home theater room, another option is to cover the wall with felt or some other similar fabric. That can reduce both light and sound reflections.) [BAN2]
To paint the wall, proceed as follows:
1. Mount your projector and set the image size to what you want it to be. Project a focused image that is either full 16:9 or full 2.4, depending on which screen aspect ratio you are going to create. Any image will do as long as it is bright at all four edges so the limits of your screen surface are obvious and clearly delineated.
2. Use a level to make sure the top edge of the picture is absolutely horizontal. Once you paint the screen, it is difficult to fix this type of error.
3. With the projected image now in the desired position on the wall, use masking tape to mark off each side of the image along the inside edge. When you are done, you will have a rectangle of tape on the wall, the outside edge of which defines the edge of your screen area.
4. Paint the wall outside the screen area. If necessary, apply a second coat after the first coat dries. When you are done painting the wall, remove the masking tape before the paint dries in order to get a clean edge.
Now that you have painted the wall surrounding your screen, you are ready to paint the screen itself. Follow these steps:
1. After the paint on the surrounding wall outside the screen area has dried, re-apply masking tape. This time, lay the tape on the outside edge of the image, on the newly painted surface. When you are done, you will have a rectangle of tape on the wall, the inside edge of which defines the limit of your screen area.
2. Within the screen area, sand the wall smooth. Spackle up any holes, dents, and imperfections. You want the surface to be as smooth as possible. Any imperfection you leave on the wall may show up as an artifact in your image. Vacuum up all the dust you create by sanding and prepping the screen area; vacuum the wall itself as well as the surrounding area below. (You might want to move this step to the top, and perform the sanding and prep work on the screen area prior to any painting. Your choice.) [BAN1]
3. Apply a coat of primer, which costs about $10 a quart. One quart should be sufficient unless your screen exceeds about 75 square feet (a 120" diagonal 16:9 screen is 43 square feet). Allow the primer to dry.
EDITOR'S NOTE (FEB 19, 2018): Evidently Sherman Williams has changed the formula for the paint recommended in this article. We have not done any further retesting or searching for an alternative paint to recommend. Please DO NOT buy the Sherwin-Williams ProClassic Smooth Enamel Satin Extra White, # B20 W 51, which was recommended in the article as written in 2011. It is now too glossy.
![]()
4. Apply your first coat of Sherwin-Williams ProClassic Smooth Enamel Satin Extra White, # B20 W 51. Use a tight nap paint roller (with nap no more than 1/4"). Make sure to use enough, but not too much paint. If you don't use enough, you will not have enough coverage. If you use too much paint, you will end up with drips that will eventually show up as unevenness in the surface. Be cautious, and err on the side of not using enough paint, as you can always add a bit more. [BAN2]
8. Allow the first coat to dry, then apply a second coat, with the same attention to creating the smoothest surface you can. One quart of paint should be enough for two coats on a 120" 16:9 screen. If your screen is any larger than that, a second quart may be needed. Before the paint is dry, remove the masking tape. Removing the tape after the paint is dry can result in chips and cracks along the edge.
Finishing Touches
Let the paint dry and cure for a few days before evaluating the final result. Despite the use of a roller with a tight nap and paint that is designed to produce a smooth surface, there may still be some uneven flaws in the surface. Illuminating it with the 100 IRE solid white pattern will reveal any flaws that may exist. The surface might be perfectly fine, and not need any attention. But if you see shiny highlights that appear as artifacts in the white light, you may want to touch them up. These are pretty much invisible when viewing typical video or film content, but easy to see when projecting a pure white image. Nevertheless, we want to remove them to the extent we can.
When we saw a few of these, our first thought was to sand the surface with a fine grain sandpaper. So we did, and discovered that was a very bad idea. The sandpaper gets rid of unwanted highlights, but it also alters the reflectivity of the surface. Sanding the surface will introduce sandpaper strokes as texture in the image, and these are as bad as the highlights they remove.
The solution is to use a very light touch. Standing back and viewing the surface in projected white light, note exactly where the excessively shiny highlights are. With a fine grain sanding block (available in the paint department at your hardware store) use the corner of the block to gently rub the highlight itself, in order to lightly buff only the immediate point of reflection. This eliminates the glare from each spot, without creating any visible artifacts in the image.
By following these steps, we were able to create a remarkably smooth, perfectly color balanced reflection surface that rivals the finest professional home theater screens. The paint we ended up preferring was the Sherwin-Williams ProClassic, Extra White, Satin, Smooth Enamel Finish, # B20 W 51. It retails for $19.49 per quart. One quart is enough to do a double coat of paint on a 120" diagonal 16:9 screen surface.
Creating the Frame
At this point in the project, you have created a perfectly white rectangle surrounded by a darker wall. All you need now is a black frame to finish it off. There is a cheap and easy way to do this. There is also a more stylish and elegant way to do it that costs a bit more but looks a lot better. Either one will work, so you can pick the one you feel is right for you.
The cheap and easy solution is to get some black velvet tape that is made for screen borders. There are several suppliers of this type of product. You can find them by googling "black home theater screen tape." We have not tested any of them, and cannot recommend one over another. [BAN1]
Basically, you can acquire a roll of screen border tape, apply it around the outside edge of your screen surface, and you are done. That's about as simple as it gets.
At this point, you've invested $20 for a quart of paint, $10 for primer, $30 for a roll of black velvet tape, and some pocket change for miscellaneous paint supplies like a paint roller, drop cloth, masking tape, sanding block, sand paper, and so on. What you end up with is a beautiful projection surface that will produce a magnificent picture.
A Better Looking Frame Solution
The aesthetic problem with the tape is that is doesn't have much three dimensional effect. It looks...um...like you stuck tape on your wall. That's not an issue when you are watching in the dark. But when the home theater is not in operation, having tape stuck to the wall might not have the class and finesse that you'd prefer.
The alternative is to make a wood frame, wrap it in black velveteen, and hang it like a picture frame over your painted screen area. Velveteen is a cotton fabric that superficially resembles velvet, which is made of silk. But velveteen absorbs light better than velvet, and it doesn't have the sheen. It is widely available in fabric stores.
The frame can be constructed of pine or poplar, woods that commonly come in 1"x4" configurations, in convenient lengths of 6, 8, 10, and 12 feet. The type of wood is not so important as the fact that the pieces you select are straight and sturdy. You don't want your frame bowing outward from the wall due to curves in the wood.
The 1"x4" format has the advantage of being exactly 3.25" in actual width. That is precisely the width of the frames on Stewart's home theater screens. So you will end up with a DIY solution that is a remarkably close replica of an outstanding professional screen. Another advantage to the 1x4 wood frame is that it will give you a three-dimensional look without being too heavy or cumbersome to mount. A finished frame made of poplar for a 120" diagonal 16:9 screen will weigh under 25 lbs. [BAN2]
How to Build the Frame
Acquire four pieces of 1x4, in lengths that exceed the horizontal and vertical dimensions of your screen. Cut the ends to 45 degree angles (note...these cuts must be exactly 45 degrees!). We suggest cutting the short side of each board to a length of 1" less than the screen surface on the wall. That will give you a bit of leeway in hanging the frame to cover the entire painted surface without having to be exact down to the millimeter. So for example, if the width of your screen is 105", get two 10 foot 1x4's and cut them to 104" along the edge that will be adjacent to the screen.
Once you have cut the ends of each section of the frame to 45 degrees, join them together with flat metal 8" L-brackets, as illustrated here...
Attaching the Hanging Hardware
The easiest way to hang the frame is to use two flat metal D-rings which are available at most large frame shops, along with two picture hanging hooks you will nail to the wall.
Now some careful measurements are required. For maximum support, you want to place the picture hangers where the studs are in the wall. Along the top edge of your screen, knock on the wall until you hear the shallow, high pitched knock that indicates the presence of a stud. Place a small mark at the center of the stud. Find the studs that are closest to the sides of your screen. Measure the distance from the side edges of the screen to the center of the stud. Then on the back of the frame, along the top horizontal section, measure that same distance from the inside edges of the frame. This is where you will attach the D-rings.
The D-rings should be screwed into place along the bottom edge of the frame, as shown here:
The reason you want the D-rings along the bottom edge is that you want the picture hangers to be hidden behind the frame once the frame is mounted. As you can see, the D-ring plus the picture hanger will take the full width of the frame:
Attaching the Fabric
Once the L-brackets and D-rings are screwed down, your wood frame is assembled with the hanging hardware in place. All you need to do now is wrap each side of the frame in velveteen.
Acquire one piece of this fabric that is about one foot longer than the width of your screen. The reason is this...if your screen surface itself is 105" wide, the frame on the outside edge will be an additional 6.5" in length (since the wood frame itself is 3.25" on each side. That ends up being a total of 111.5". You want the fabric to cover that entire length without having to cut multiple pieces. And you want a little extra on each end so you can trim it to precisely where you want it.
From the single piece of velveteen, cut two strips long enough to cover the horizontal segments, and two strips long enough to cover the vertical segments. All four strips of fabric should be 7.5" in width, and long enough that the fabric will extend several inches beyond the length of each segment of the frame you are going to wrap.
Now you need a clean surface...either a clean carpeted floor, or lay down a drop cloth or bedsheet. Lay the fabric face down on the floor, then place the frame segment on top of it so it is centered. Fold the fabric over to the back side of the frame and tack it into place with a staple gun. Carefully trim the ends so that the fabric overlaps and the corners are covered. Along the top segment, trim away the fabric from the D-rings to leave them exposed.
Once you have tacked and trimmed the velveteen on all four sides, your frame is ready to hang. Assuming you are using the picture hangers depicted above, you may want to crimp the lip down a bit, just to the point where you can slide the D-ring into it. If it extrudes too much it will hold the frame away from the wall slightly.
Nail the picture hangers to the stud locations you marked on the wall. Assuming you are using the hangers depicted above, the top edge of the hanger should be 3" above the edge of your painted screen, positioning them so they will support the frame in the position you need to cover the screen area.
Piece of cake. You are done.
What you have just created is a beautiful replica of one of the finest screens in the world. But instead of spending $2,000 or more for it, you spent about $100 (if you used the border tape), and under $200 if you went all out with the elegant wood frame. Either way, this painted screen will make your 1080p home theater projector look awesome.
A Word of Caution
All of this sounds good, but there are a few things you might want to think about before taking this project on. See the next page for problems and issues to consider before you start. We do not recommend painted DIY screens for everyone.
FOUR Reasons NOT to Paint your own Screen
Since this article is about creating the perfect screen for $100, it may seem odd to finish with reasons you might not want to do this. But it is important to think through all of your options. For many people, buying a screen will be the better alternative. Here are four reasons not to paint a screen...
[BAN2]1. Ultimate quality. Some people want the best, and are willing to pay for the best no matter what. Especially if you are budgeting $3,000 to $5,000 and up for a high quality projection system, you will want the best possible screen available to go with it. Though the paint we recommend here does a great job, it is most appropriate for first time home theater buyers who want to limit their investments. It does not match the brilliance of, for example, our Stewart Studiotek 130. It has higher gain and more brilliance than the Studiotek 100. Putting our painted test board up against the Studiotek 130, the 130 wins hands down. If you want to get the best picture possible from a top quality projector, you want either the Stewart Studiotek 130, or a similar product from Da-Lite, Draper, Vu-tec, and other companies that manufacture high performance professional screens. [BAN1]
2. Convenience. There is also the matter of convenience to consider. All screen manufacturers make fixed frame products that snap together in under an hour. This is MUCH easier and quicker than the messy sanding and painting required for the DIY screen discussed here. If you do the painting right, between the prep work and allowing primer and paint to dry between applications, it will take several days of mess to get it all put together. You can get nice looking screens with frames that snap together from companies like Carada and Elite. They cost more than the DIY solution discussed here, but they are much less than what you'd pay for screens from top quality producers.
3. Do you want a fixed frame? The fact is, you may not want a permanent fixed frame screen on your wall at all. If your viewing space is a living room or multi-purpose room, having a big screen staring at you when not in use can be annoying. Many people prefer electric screens that descend from the ceiling when you want to use them, and retract and disappear when you don't. For a room that you use for social entertainment, and things other than just watching movies, the electric "disappearing" screen is much easier to live with.
4. Is there a move in your future? If you are going to move, obviously you can't take your painted masterpiece with you. If you buy a snap-together fixed frame screen, you simply take it down, pack it up, and reinstall it in your next house or apartment.
So our $100 painted screen is not for everyone. It is great for the person who loves DIY projects and gets a kick out of creating excellent home grown solutions. It is great for those who have a dedicated wall, who don't mind a fixed screen on the wall, and won't be moving soon. And it is great for those who want a beautiful screen for not much cash at all. In the end, it is just one more option in your search for the best home theater experience you can afford.
Thank You for your continuing insight,
Steve
#1 So basically you are saying white is better than gray? #2 ProClassic Smooth Enamel Satin Finish is the paint that you have chosen as the best one, but if im painting on wall it should be Duration Satin Extra White right? #3 Could you post some pics?
The bottom line is don't be afraid to experiment; a painted screen can work very well with minium expense.
My one criticism, is the suggestion of painting directly to the wall. This makes the assumption you already have a flat and smooth wall surface. Most residential drywall work these days is pretty sub par, and walls are finished with a texture to hide imperfections in construction. Like others have suggested, painting some sort of sheet good may be a better solution. Of course that limits screen size or introduces seams on the surface.
I would also suggest using pre-engineered wood trims and moldings found at most home improvement stores for the frame. They usually come pre-primed and ready for paint, and they will be straighter and more dimensionally stable.
Thanks for your article.

I started looking for alternatives: I called Screen Innovations and they would not sell me just a couple of rolls of Black Diamond, no matter how much I begged. My screen is 156" and their limit is something like 140" so I would need more than 1 piece.
I kept hearing about Bahr Silver Cinema color but putting that swath (and others) on my wall lowered brightness too much for me. Even at maximum (2000 Lumens) brightness my over-sized screen didn't look right. Contrast was slightly improved though. Ultra Pure White was brighter but showed VERY poor Contrast, especially in the day-time.
I was just about to pull the trigger on Screen Goo when I saw this article at Projector Central about a $100 painted screen. Since I don't have a framed mask, that's more like $50 to me.
This time around I didn't paint the whole wall. I just painted a 156" rectangle based upon the 17' projector throw. The Sherwin Williams Paint is just grey of white with a slightly blue (high color temp) to my eyes - I guess I don't know what the color white looks like. It has a 1.1 Gain. I had to drop my projector down to 6500K but WHOA! This thing looked great. It was brighter with more accurate colors and only a small loss in black level. I am going to have to recalibrate all of the projector's picture modes.
This was a big improvement and definitely worth the $50. I may still go to Screen Goo in the future. $300 is still much cheaper than $5000 and I have a feeling brightness and contrast will improve even more.
A stunner of an article! Highly recommended.
P.S. I was so eager to see what the picture looked like after the first coat I turned my projector on before the paint was dry and was horrified at the "starfield of speckles" I saw. I thought I was going to have to get a quart of Flat and go over it. About an hour and a half later it settled down, though. The second coat the next day went the same way.
Thanks PC.
My needs have changed and I notice flaws over time. Mainly, it's the wall, not the paint. Drywall seams and the lack of super smooth surface and the main problems. I'm moving to a rigid frame for my next screen.
If I was doing this again, I would mount a piece of drywall with liquid nails right over the existing drywall horizontal. Other options would be to apply a thin layer of joint compound over the entire area and sand it until it was entirely flat. Either option is chasing having a flawless flat surface.
Follow the directions for the Goo paint to the letter and let each layer cure and you will be happy for years.
The airless sprayer never worked for me and yes I practaced but found the small foam roller to work best! No roller marks as In my first Goo screen.
The end result too close to call.
My recommendation is to buy an 8'x4' sheet of faux maple paneling at Home Depot. This is a perfectly smooth laminated sheet - make sure there are no flaws but this is much better and lighter than drywall. You can built a frame for it out of wood.
This sheet is like $14 so it keeps the costs down too and you get perfectly smooth. Be sure to prime it first then use the Screen Goo systems.
At Hometheatershack.com there is a DIY paint mix called black widow that will measure spot on 6500 degrees kelvin.
It seems to me that a really good option for smaller screens would be MDF or Hardboard. If your screen is smaller than 4'x8', one sheet will cost about $20 and is prefectly smooth. That would me much easier than messing with plaster, which is noted as being extremely messy.
Also, MDF would be a good option for the frame material. You'll be hard-pressed to find any poplar or pine that's perfectly straight direct from the home store. However, MDF is perfectly flat, perfectly straight when cut correctly, and it won't warp. You can have HD use their panel cutter to cut a MDF sheet down to the strips of material you need. They're not accurate to the 1/16th of an inch, but it's close enough.
The wall was carefully wet-sanded, I used a high-density foam roller, and even experimented with thinning the paint.
I think this problem is directly related to the brighness of the image. The brighter the image, the more glossy paints will show the imperfections. I'm using only a 82" image with a fairly bright projector, which makes the image too bright for glossy paint. The amount of ambient light is probably also related. I don't have exact numbers, but my thought is to stay with flat when the image brightness is over 25fc.
But I have to admit that after reading this article, I'm thinking of repainting again...
Thanks very much! Richard
To level the paint try using Flo-trol paint additive, works great. Slows the drying and really levels the surface.
I'm now going to paint the screen with the Sherwin-Williams ProClassic, Extra White, Satin, Smooth Enamel Finish, # B20 W 51 paint after reading this. I'm going to spray it becasue I have the equip and skills so why not. Love this site! Keep up the great work!!
What is important is that there be no glossy marks (food stains, sellotape, crayola, etc). These can be easily removed with a scouring pad and detergent. Perfect smoothness is also not necessary because the light from the projector is near vertical to the screen, and anyhow imperfections are invisible from 15‘ away.
The greatest viewing improvement for me came from attaching black hessian fabric to the whole ceiling (with stapels and wooden battens). The room is total blackout, with floor-to-ceiling navy blue curtains all round, a dark carpet, and dark furnishings. No light reflected back to the screen. With all that, I never even notice or think about the screen, and the PT-AE1000 is more than bright enough. I have designed adjustable borders for different aspect ratios, but the lack of borders is barely noticable in the dark and not distracting, and I haven’t bothered making them.
The trick is in painting the wall color on the inside, some of the wall color will seep under the tape in an uneven manner. This is ok because it is the same color as the wall. However, it will seal the uneveness so that the screen color does not seep under the tape.
I haven't done a screen on a wall yet, but I have used this technique on highly textured walls and it works great. They should print this technique on the painter's tape.
Good luck.
Dave
It worked great and I think the picture is better than before! Its smoother because the paint 'settles' into the wall and fills in the unevenness.
Also the color seems to be remarkably 'pure'. Its not 'warm' or 'cool', its neutral.
Finally, give it time to 'cure' to its final state. I noticed that the color seemed to change a little over a few days time.
But its worth it. I had a friend over and he said, "Whoa! is that a special screen? It looks so good!"
Mike
first I marker out the full view on the wall and I put down two coats Sherman Williams (SW) white primer over a light yellow wall to start. then put on two coats of the recommend Sherwin-Williams ProClassic Smooth mentioned above.
I then used 3.25 inch wood trim painted it flat black first and then trimmed out the full screen view (this is a two person job and have the right tools so it looks professional)
Thanks for this projector central write up for $60 (max) I have a $200 screen and it will blow your friends away.
Good Luck!
I followed everything here and so far with only one coat of paint things look 100 times better that just projecting to a clean, smooth wall.
When we get the second coat on, and watch a 3D Blu Ray I'll get back to you. So far, so great! Thanks again!
Very please with the painting process and the Epson 3010. Thanks again!
Just an FYI that, in Canada, I was told by my Sherwin Williams store that the code for the equivalent ProClassic Interior Acrylic Latex (smooth enamel finish for trim & doors) Satin, Extra White is B20 WQ 8051
I live in Haiti where Sherwin-williams paint is available. I want to project to a large external wall at night, for a drive-in. Do you think the exterior version of Duration satin works??
http://www.sherwin-williams.com/homeowners/products/catalog/duration-exterior-acrylic-latex/?referringCategory=exterior-paint-coatings/paint/
It is rare that people writing on the Internet do such an excellent job of research. I would like to add my praise to the heaped-up pile.
Thanks again. Victor
My entire project involved "level 5" walls and ceiling on every square inch of it which is what I wanted and I love it. My screen wall was done with shims and 5/8" wall board to ensure the flattest most stable wall I could make and it was worth the effort. I used Behr primer since I find it to be far superior than other brands especially "Kilz" which is junk (by the way I'm a builder and use lots of products, so feel qualified to say so" I will say also that Sherwin Williams is far over priced and you can just wait for a sale to buy yours (usually 40% off) gallons are $75 or so at retail. Sherwin Williams also makes more than one "Pro Classic" and yes it matters one is Latex and one is Acrylic (use the Acrylic) it paints out wetter and isn't as hard to use, it also leaves a better finish.
I used the Latex the first time and got a dry line going which I ended up chasing and unable to fix by recoating (this is why I say to use the Acrylic) Sherwin Williams "replace for free" that gallon of Latex with the Acrylic and it's so so much better. I used a 6" super fine no nap roller and 4 coats on the initial run, than after discovery of the problem lightly sanded the problem and recoated the whole thing again which made a fantastic screen of 10' horizontal. So my thoughts of this screen is I wouldn't do anything different than what I did, I think it's as good as anyone could ever want, I'm using a new Panasonic PT AR100 and I'm happy with it it's plenty white and bright enough but would certainly consider a better one if I had money to burn like a higher end Epson. Two thumbs up to Projector Central for doing this challenge and writing this article!!!
I am getting ready to finish my screen and the room has ambient light, but controlled ambient light. However the ceiling is white. I have read that a Grey screen would be better in this situation.
Can anyone here advise if they had the same situation and how did they decide between this paint here in White vs. Gray?
My only comments are these, First mount and adjust your projector to find where and what you want to paint. That's the great thing about painting, you don't have to worry about buying a screen when you can paint the exact size you want, i.e. if your wall size fits a 107" best, then paint it that size.
Second sand your walls as smooth as you can, if painting over an already painted wall as in my situation. I even had to put a bit of putty in a few holes I found, or filled in an uneven section of the drywall. With a bit of diligence with prep work the wall will turn out great.
My third point, is customization of the trim for the screen. I did not use the articles method. From a local hardware store I found 1 1/4" molding, black spray paint, and Velcro squares (yes Velcro squares about 3/4" in size). I painted the the molding in full length, then cut the molding the correct length for top/bottom and sides of screen. I did not miter the joints as I'm not that good at cutting free hand, so I simply squared off the ends. I then made little squares from some extra lath I had laying around and used those in the corners and butted the top/bottom and sides to those like they did in older homes. With the Velcro I put one on every 10" to 11" of the top/bottom and sides, and then attached the entire molding piece plus both sides of the Velcro to the wall. This way nothing is screwed into the wall and it comes of easy. I needed this option because my kids play in my basement and could easily rip any thing off the walls accidentally. This way if they do, it should only be a bottom or side piece and will Velcro right back on the wall! Good painting!
Thank you.
I have just finished that and am now masking up the inside edge of the white screen and now using the same paint "acrylic enamel - flat" but ULTRA DEEP BASE and BLACK. i will paint this all around the white screen 2 coats.
I highly recommend getting paint stores to PUMP up the white forumlas with more white pigment, cheap paint they save on costs by reducing the ammount of titanium dioxide in the paint. im pretty sure thats what it is.. might be wrong. but having a CHALK looking dead flat projector wall looks MINT!
Used the SW Proclassic and screen looks good with the exception of one spot on the screen that can be seen when light colors are displayed. Looking at the screen this appears to be a spot where my painter may have sanded a small area. What is the best way to correct this problem?
I bought a BenQ W1080ST a few weeks ago. I’ve been watching TV and movies against the painted wall and it looked good. After reading this article, I went to Sherwin Williams and purchased 1 quart of multi-purpose primer and 1 quart of ProClassic® Interior Acrylic Latex Enamel (B20W1151). FYI, there is a coupon on their website for $10 off if you spend $50.
Fixed some spots with drywall repair mud and let it dry. I sanded the repairs and put on the first coat of primer. After the primer dried, I saw a lot more imperfections in the wall including a seam in between the sheets of drywall. Patched over the seam, fixed all the issues I could. Let it dry overnight then I sanded the fixes and wiped down the wall. Painted second primer coat (not sure I needed two coats of primer but figured it couldn’t hurt.) After 4 hours, I applied the first latex coat. For that coat, I found this site for painting techniques "http://www.avsforum.com/t/929997/beginners-guide-to-simple-diy-painted-screens" about halfway down the page under the “Flat Paint Rolling Tips” there is a link to a video that shows how to apply the paint. I used the 2 roller technique, the regular 9” to put the paint on the wall and the 6” roller to smooth it out. After the first coat, I watched the movie “42” that night. Was very impressed but there were some areas where the wall was brighter with what looked like little holes, think moon surface. I put the rollers in the fridge overnight to keep them wet. The next day I painted the second coat. A couple hours after finishing, I started watching football. It looked terrible. Not very clear, colors saturated. I was worried but patience is the key. By the time the night game came on (after 4-5 hours), the paint dried and it looked great. I was blown away at the depth of color, the pop of the screen, etc. I checked movies and 3D too. They look even better. If you are reading this, I know there are a lot of comments in this thread and it gets distracting. I just want to say the solution spelled out in this article just works. I spent less than $50 on paint and I am very happy with the results. Do it! It takes a some effort but it’s definitely worth it.
i read you used a "semi gloss paint" if so. you will have to repaint the whole screen. any stopstarts or area you try to "touch up" will have a sheen break in it and be visible.
just out of interest why did you go for semigloss?
Cheers, Buster.
Fantastic tip! Thanks! It's nice to see constructive and helpful comments.
So this will do the trick, and I thank you again M. Powell and all people that participated in this test! :D
Thanks a lot in adavance!
As I live in Denmark I'm not able to get the Proclassic paint, however can someone tell me what the "satin" finish relates to in terms of reflectivity value, so I can try some paints from the local dealer!?
Thanks
Thanks
I took the advice in this article, and I was floored after the application of the primer coat only. I may not be as picky as some readers here, but I am an avid movie watcher and actor, and I have a full home theatre system. So I have an appreciation for a quality viewing experience. Anyway, I am currently renting and I cannot sand the walls without expecting to pay a large penalty upon moving, so I followed all the instructions except for any major modifications to the surface.
It's day one after completing the project, and I cannot believe the quality of the image. It's 100 times better than my Elite. I wish I had done this sooner. I was even able to get a decent picture with the blinds closed while the sun was out. This was not previously possible with my Elite. I can see the light texture of the wall when the image is very bright or all white (mostly when I have my laptop hooked up because web pages have lots of white, I realized).
All that being said, I couldn't be more satisfied. Well worth the $88 dollars I spent a Sherwin Williams. I may give away my Elite screen at this point. Not only is the image better, I am not restricted to the 120" screen size. I painted a screen that is a little over 140" diagonal (approx. 122" x 69"). This project was so easy to do and these detailed instructions were awesome.
It's great to see such a great article at an age when I am so skeptical of easy solutions and at a time when the web is so full of misinformation and empty promises.
Thanks, Evan & Project Central!!!! You guys are awesome!
Shane
Great instructions here, BTW--very thorough.
Then I came across this article and decided to try painting that wall. It's like having a completely different projector now. The colors are right, the picture is sharp and clear, it works in a room with ambient daylight now better than it did in a darkened room at night, and the video has a vibrancy that I hadn't even hoped to see with such an inexpensive setup. Thank you so much for testing the different paints and posting this! Between the paint, drop cloths, roller and a pan and masking tape I probably spent less than $50. If it had cost me 4 times as much it would have been worth it.
Thanks for taking the time to do this article, the guy at our local Sherwin Willaims shop says he loves this article because it seels so much of this paint.
I primed, sanded the primer, and then cleaned the dust off the surface. As with the article I'm noticing a few spots that are too reflective. Overall he image is phenomenal!
Thank you very much in advance for your co-operation,advice & time.

I wonder if the SW paint in the review would be an improvement?
For the recommended paint to work well, we are talking a perfectly prepared screen. I know it is mentioned, but since you are using a reflective paint, it is absolutely true.
IMO with today's higher lumen projectors I recommend going to your local store who sells paint and get their whitest white in Flat Interior Enamel. This will be much more like your LCD/Plasma screen, so much more forgiving on screen prep, which can be far from perfect using flat paint. Easy to prep and paint and be done. The picture is stunning, not glossy, just solid wow. If you are a silver fan, same idea in the shade you like. I don't believe we need gain, in many cases we are knocking down the brightness as-is.
IMO this can be done for right at $20, with roller, pan, tape and quart of paint and about 15 minutes. Perhaps two coats, depends on where you are starting at, but 1 or two coats when done, it will dry perfect with no spots, if possible project an all white screen to inspect any blemishes.
I am now on my 3rd generation projector and electronics, and have never felt any desire to upgrade my screen.
I strongly recommend this method, with the caveats listed - but would add another: If you are planning to move, just leave the screen in place as a value-add for the next owner or tenant. It's too much hassle to move. Explain it to the landlord who can sell it as a feature to prospective tenants. Another friend did just that and the landlord loved it.
I may be a bit late coming into this discussion, but I am about to paint the wall I am projecting onto and came across this article. Thank you to Evan for putting all the time and effort into researching the ideal paint.
It seems that the Sherwin-Williams ProClassic Smooth Enamel Satin Finish is definitely the one! One problem, I'm based in the UK and thus far I haven't been able to get hold of it. Does anyone have any suggestions? Is there anything available in the UK which is the equivalent of this paint??
Many thanks, Anton
I have bought an Epson 2030 , 3LCD, 3D, 1080 Pix, 2000 Lumens projector. What is the recommended paint for the wall? I will have a contractor paint it.
Any idea how this Sherwin Williams painted screen might compare to the Silver Fire painted screen or the Silver Ticket screen from Amazon? The projector is an Optoma HD50/HD161X
Can this not be counteracted by adjusting the projectors RGB values?
I've tried adjusting the focus but it is no help.
After attempting to sand down the small dimples from the 3/16 roller, which left the screen uncceptable, and applying about four to five additional coats with a foam roller, the screen is finally acceptable, however it is not perfect. Having done all this work I have only about $50 into the entire project looking back I think I would rather have spent 200 on a fixed frame screen. However I've come this far I might try to stick it out
It just seems like there is too much sheen to this, regardless of the projector settings. I have spent so much time on this wall already trying to get the drywall perfect (still isn't, every tiny imperfection shows) but would love an alternative or idea for the hot spot.
Of course typical sheets are only 4' x etc so it can be limiting, but would be fastest/cheapest for best job.
First, I saw comments about using a foam roller vs. the 1/4" nap roller. I decided to ask the 'experts.' At Home Depot, the guy said, "foam." At Sherwin Williams, the girl said, "1/4 nap." So, I bought both to test it. The difference is very slight, but both my daughter and I thought the foam roller gave a smoother finish.
However, in looking at the areas I painted to compare, I saw how many 'dimples' still exist in the surface (not from scratches or dents in the wall, just from the drywall texture). And, I'm talking about the painted test strips, not just the primer areas. I've sanded several times, using 100, 150, 180 and 220 grit paper. The wall feels smooth, but with the right light you see all the sanding has smoothed the drywall texture, but not removed it. I am wondering how noticeable it will be. Which, I watched a couple things (a football game and a movie) after priming the wall, before painting and it looked good. That wasn't as smooth as the areas I painted to test. ... I'm only doing a 95" diagonal 1.85 screen. I'm wondering if I should go with a sheet of MDF. That would be very smooth.
Thoughts??
Is this a projector issue? Right now, I'm using a cheap 540p BenQ. I want to know if my painting is done, and I can move onto the frame.
Thanks
Time for the sanding sponge. I tried to remove as much texture as i could. This is enamel paint is durable stuff and take a little time to sand down a bit.
So on to the next chapter. After extensive research "enamel is the key factor in a screen paint." When you read about the expensive profession projection screen paints...they always mention how durable there paint is. So it lead me to the conclusion that their key ingredient is enamel!
Because of the Covid 19. Home depot and Lowes were out of the question because i wanted to add a drop of black(i did this with the Pro Classic ) So back Sherwin Williams i went out of desperation. They have an "eggshell!" enamel called ALL SURFACE ENAMEL HP. So i had them add one drop of black and i was off to the races. I didnt re prime the surface,,just sanded. Im an excellent and very fussy painter. Roll marks arent in my vocabulary but unsuspecting lint from cheap rollers are! Use a 10mm lint free roller. Sherwin Williams has a 5$ contractor grade roller that gave me and excellent finish free from lint. Trust me...i saw a quarter inch lint on a previous coat and i redid the whole thing!
I just used one coat and im Extremely happy with the results! and this is just about 2hrs of drying! Still has to dry more to flatten out the sheen bit more. The eggshell made all the difference . Its almost perfect!
Key Factors
-Use enamel based paint. Durable and have the best light reflecting capability. -I prefer white (i have a light controlled room) with just one drop of black to give it a little contrast bump and a true screen look. -Lint free 10mm roller -Try to start with a fresh sheet of drywall or even a sheet of 4x8 panelling which is much lighter and smoother. Less coats the better. The more coats u add, the more unwanted texture you might have. -Matte based enamel exist in other brands will be a good option as well. -100" screen was all i could fit into my basement so 4x8 feet sheet worked perfect. Just needed to cut 10inches off one side.
I will write a follow up in a couple days once the paint is fully cured.
Sherwin Williams ALL SURFACE ENAMEL HP Egg Shell with one drop of black.
I have a Optoma DLP HDX 146. I run it on eco mode and i really dont see how this picture with this paint can be beat at this price point. Ill go on a limb and say the colors pop as if it was a 100" Plasma!
My settings are RGB Limited on my pc. and cool picture temp on the Optoma. No other adjustment are necessary.
A painted screen shouldnt be painted with just your basic flat paint. It doesnt make the image and movies pop and come alive like the enamel finish does. You have to have a little sheen.
I also found that ycbcr 422 10 bit setting is better suited for viewing most movies. I believed i mentioned to lock it in on RGB setting. This is false unless your viewing images on a computer. Youll need two coats. I mentioned i only used one because i already had a very close match the previous time. I also heard Glidden has a Matte Enamel paint only sold in the US. I would be curious to see how that would turn out.
You can contact me at kjasey1@gmail.com i can send you a pick of the info on top of the can.
