I'm, Ron Burgundy?
I went and bought some new tile flooring today for my living room because the Home Depot had on hell of a deal on it. Anyways, I got the spacers, tile, grout, and thin set. Anybody know if I can lay thinset over my existing floor? It's an old hardwood floor from the 1920's or so. Or do I need to get the backerboard for it?
