Preparing a floor for peel and stick tile is easy. The floor needs to be thoroughly cleaned before installation. Peel and stick tiling sticks wonderfully to floors made of wood or concrete but you will need to do a little more preparation for other materials or if your flooring is not in good condition. If your floor has any gaps, cracks, or holes, it will need to be filled in with a floor patching compound for best results. Once the compound is dry, sand the patches until the entire surface is smooth and then lay down your flooring. If your floor is waxed, you will need to prepare it a little differently as you will be required to remove all wax before laying down your tiles. In most cases, you can do this using a quarter cup of ammonia mixed with a gallon of warm water.
