Pay attention to the size as well. Beyond the size of the individual tiles, note the dimensions of each self-adhesive sheet or piece, which might have anywhere from eight to 50 tiles on it, depending on the scale. When browsing options, make sure the material is suitable for the room you plan to install it. Why? Tiles applied to walls in a bathroom or kitchen will have different requirements than those used for something like an entryway accent wall. If damage to the existing tile does occur, use a blow dryer to warm up the adhesive, then gently peel the damaged tile off and prepare the surface for the installation of the new tile. In most cases, small patches can be completed without needing to move or reassemble the surrounding tiles. Just make sure that the replacement tile is facing the correct direction so that the repair blends in seamlessly with the existing pattern.
