I removed the carpet in my bathroom and there is some mold by the edge of the tub. Can I install SnapStone over it?
A. Not until a few things are done. First find out the source of the moisture and correct it. Next, check to see if the moisture has caused structural damage to the floor (if unsure consult a carpenter). Repair if needed. If the floor is structurally sound, clean with a 1:9 bleach and water solution and rinse. Be sure to allow the floor to completely dry before installing SnapStone.
