How to Install Ceiling Tiles and Grout
- 1). Clean the ceiling so that the “old” surface (what you will be covering with the new tiles) will accept the glue and tiles better.
- 2). Determine where the exact middle of your ceiling is. Do this by stretching two pieces of yarn, string, thin rope or other similar material from corner to corner in an “x” design. (See TIPS for further information.)
- 3). Using the point where the two strings meet in the middle, draw up-and-down lines (“+”). This will divide your ceiling into four distinct, even areas.
- 4). Select a tile to be your middle piece, and apply the tile glue (“mastic”) to the back of the tile. Don’t spread the glue; rather, apply it in little “hills” or piles at least one-half inch high. (See TIPS for more information). The tile glue should definitely be applied to all four corners as well as the middle of the tile, with more glue being added between those spots as or if needed.
- 5). Line up one of the corners of the first tile piece with the exact middle of the ceiling, make sure the edges of the tile are following the up-and-down lines (“+”), then make sure the tile is pointing at a right angle to the walls.
- 6). When you feel you have the tile properly positioned, press hard enough to ensure that the tile sticks firmly to the ceiling, but not so hard that you break or chip the tile.
- 7). Continue installing the remaining tiles, working from the middle of the room to one corner (say, the left one) then, from the middle to the opposite corner. You want to go straight across the ceiling. Make sure the tiles are fitting as close to each other as possible. (See the WARNINGS section.)
- 8). Cut the tiles to fit the corners and along the edges where the wall meets the ceiling, if necessary.
- 9). Use the caulking gun to squirt the caulk onto the tile seams, then use your finger to push the caulk up into the seams.

Promptly wipe up excess caulk with a damp rag or sponge. Once it dries, it will be harder to clean off.
