Prepare a clean surface for applying the adhesive. Dirt or debris can limit the total effectiveness of the adhesive.
-
2
Level wall surfaces using a layer of drywall compound applied to the wall or by securing a drywall panel to the wall covered with a thin layer of drywall compound to serve as a surface for the adhesive. For moist areas, use moisture resistant green board panels secured to the wall.

Level floor surfaces by grinding down high surface areas with a concrete grinder or floor sander and filling in low areas with wood putty or self-leveling compound.
-
4
Prepare painted walls by providing a texture for the adhesive to stick to. Texture can be created by lightly sanding the painted surface with sandpaper.
-
5
Chose an adhesive that's made specifically for the wall type and installation environment. Some adhesives work better in moisture rich environments than in dry ones. If mixing of the adhesive is necessary, mix it according to the manufacturer's instructions.

Use an adequate amount of adhesive when mounting the tiles. The adhesive should be spread evenly to the surface using the flat side of a trowel and then raised into a series of ridges with the notched edge. You can tell if there is an adequate amount of adhesive by mounting a tile using a slight twisting motion and then removing the tile and examining the back. If the back of the tile is completely covered with the adhesive, then there is a proper of amount; if there are blank places, either increase the amount of adhesive placed on the surface or use larger notches to raise the ridges.
