1. Prepare the surface: Wipe off the ceiling or any other surface you are installing the tiles over, and make that surface smooth and even. Remove loose plaster, paint, wall paper etc. Draw a chalk line in the middle of the room (preferably through the light fixture electrical box area).
2. Apply the adhesive: Apply any good quality rubber based adhesive (we recommend Contact Cement by DAP (Weldwood Original Formula) to the back of the tile. Let them air out until adhesive solvents evaporates and becomes tacky. Please check the drying time on the pack of the adhesive, usually it is anywhere between 2-5 minutes.
Applying the adhesive on the ceiling will also improve bonding and strength. Approximately 1 gallon of adhesive will be enough to cover 75 tiles or 300 square feet when used on both, the tiles and the ceiling.
3. Place & Press: Place the sheet in the required position and press firmly but gently. Overlap the edges with the previous sheet and press firmly with fingertips, after completing the first straight row, work your way to the sides.
