Currently, the basement has an old tile floor, ontop of the cement foundation, that gets alot of traffic as it's our party room. Some of the tiles are cracked and chipped but most are still in tact. Can I install flooring directly over the tile floor or do I need to remove the old tiles first. I'm thinking of a more decorative tile, wood flooring or even carpet tiles. Some of the products seem very easy to do yourself. Does anyone have any tips for doing this? Or any products I should get that would make the installation go alot smoother?
