The tile is the old 1"x1" (maybe 2x2) but the colors were ugly. We had carpet put in but my wife has destroyed it with hair coloring spilling. We saw the Allure product and really like it. The HomeDepot guy said we didn't need to do anything to the tile. But I've read some posts about mosture problems. We have a basement, so the tile is on a wood floor. Do I need to seal the tile or use a moisture barrier like I did on my laminate flooring? Any help is greatly appreciated.
