I just purchased a condo and removed all the carpeting. I had the bedrooms re-carpeted but planned on laying hardwoods in the living areas.
The problem is that now I realize that my floors are pretty uneven and have several large cracks in the light weight concrete. The carpet guy said it wasn't a big deal and that he sees it all the time. He also mentioned that you can buy a self leveling compound that you pretty much just pour on the floor and let it find all the dips and valleys.
Does anyone have any experience with this stuff? It sounds like something I could do but wanted to hear other experiences.
