A plywood ceiling is going to be warm and comfortable looking and will go well in a contemporary look. Plywood comes in several varieties, so you will need to choose the right look for your room.
Step 1—Get Ready
Measure the room and get enough plywood to do it. If you are buying the squares precut, make sure they are all of the same lot number. There will be a difference in shading otherwise.
Step 2—Measure the Room
Measure the ceiling into a grid of 2′×2′ squares to hold the tiles. You can skip this if you aren’t planning to install the tiles as part of a suspended ceiling, but rather to glue them directly to the existing ceiling. Regardless, the next step is to use a nail gun to put finishing nails around the edges of the tiles.
Step 3—Cut the Tiles
Measure the cuts so they will be even on both sides of the room and be careful with the circular saw. Use a carpenter’s square and measure twice, cut once. The tiles are either prefinished or can be stained or painted according to your taste.
