I have a relatively compact movie room with a 110" screen. Due to the vertical size of the screen it is pretty close to the ceiling. This, as many projector owners know, can be a problem with your typical white ceiling as the light bouncing off the screen will illuminate the ceiling and back to the screen again and kill the contrast and make the picture look really washed out. Since this is a bedroom I didn't want to make anything too permanent, and the goal was to make it a easily and cheaply as possible. Total cost was under $30 to create a black ceiling that extends about 5 1/2 feet from the wall, just enough to keep ceiling reflection at bay and no power tools involved.
Flower bed fabric
Black foam core board
Hot glue and hot glue gun (low temp)
Place double-sided tape in dispersed pattern. This will keep the fabric from sliding off and help keep it from sagging in the future.
Determine which is the duller side. This is the side you want exposed as it will absorb light better than the other side. The easiest way to figure this out is, at least with the fabric I used, the side with the smaller squares is the dull side.
Once you've cut it down to size place it on top of your board, smoothing it out with your hands from the center and working your way out. Doesn't have to be perfectly smooth, just enough.
Flip the board so the fabric is underneath it.
Add a about dab of hot glue to the center edge of the board closest to you. Use a low-wattage glue gun for this. Too much heat will deform the board.
Grab the edge of the fabric from underneath, stretch and fold it over to where the glue is and quickly press down over the glued area with your thumb (it will be a tad hot).
Repeat on the opposite sides, working your way towards the edges. If you've put together fixed projection screens this should be second nature. It's best to stand the board up vertically while stretching the fabric.
Using just five tiny pieces of mounting tape was enough to stick these up to the ceiling (on near each corner, one in the center).
Yes, it's a pirate themed room.
The masonry and woodwork is actually carved out of foam.
Cheap, yes. But effective. And best of all, 100% wife approved! I hope this post will help those looking for a cheap and easy solution to ceiling reflections.
