When it comes to making a diy projector screen, nothing is easier than simply painting a wall with Screen Goo. The problem with standard paints is that they are not quite the right texture or color, but Screen Goo paint comes in several different hues, and is specially formulated to give you a perfect viewing surface that can be essentially hidden when your home theater isn’t in use.
If you don’t want your screen “visible” unless it’s movie time, that is a simple matter of finding a close match to the color of Screen Goo you’ve chosen. You wouldn’t want to use Screen Goo for the entire wall, as it’s a bit more expensive than your standard paint, but this kind of performance is worth it. And who’s to stop you from making your entire wall into the viewing surface? Goo screens can be as large as you want them to be. If you want such a large picture, go ahead and do it, but keep in mind that your projector probably has a size where it’s going to provide you with it’s best possible picture. Going any larger will cause a degradation of picture quality.
Besides the simplicity involved in “installing” goo systems screen paint, they have a color selector that will help you pick the shade you need. They obviously are unable to determine exactly what you’re going to need, but you can input screen size, the make/model of your projector, and the typical room lighting levels, and they’ll try to match you up as best as they can.
If you are really into the idea of making your own custom projector screen, finding the right projector screen material can be difficult. You’ll be searching fabric stores for blackout material, and then you have to go through the process of installing it properly. It’s nothing compared to the ease of painting a flat surface with projector Screen Goo. If you’re leaning in this direction, rather than buying a screen, go with the Goo.
