Don’t get upset if you crack a few or the tile does not snap on your mark. They are cast ceramic and contain air bubbles and other imperfections that sometimes causes them to crack unevenly. Install the cut pieces but hand “buttering” (placing the adhesive on the backs of the tile) and placing them one by one until you have them all installed. Clean all you tools carefully. It is almost impossible to remove dried adhesive. Check over your work and make sure you did not leave adhesive sticking up out of any joint or on the face of the Tin Ceiling tiles. Using a damp sponge and your spackle knife, carefully remove any excess adhesive. Let the tile dry 24 hours.
GROUTING – Grout comes in both sanded and non-sanded types. Sanded types are intended for use where you have larger grout joints such as floors. Non-sanded is generally for walls and countertops. Mix your grout in a small, paper bucket available at paint or hardware stores.
