We're about to start tiling a kitchen floor over stripped bare concrete slab. We're going to be using 18" X 18" tile and we've started noticing that the floor has quite a few uneven spots in it up to 1/4" or so. We've heard about leveling compounds but we're kind of new to this. We already have our cabinets mounted so whatever we use we need to take that into consideration. Not sure what can be put down prior to the tile to level the floor better or if something different can be used to mount the tiles that can take up the uneven floor?
Thanks for any help or suggestions!
