I have ripped up the vinyl tile in my kitchen, cleaned to the bare concrete, set and installed base cabinets and just about ready to tile. As I have been inspecting the floor I have found the floor has some "wavey" areas where over a 3 or 4 foot distance, there might be an 1/8" or so dip. Nothing dramatic but just seems to have slight waves to some areas. I have never done tiling before and in reading have seen things about the smaller the tile the more tolerant of level, and I know the base materials for the tile can take up some slight differences, but my question is, how level does a floor need to be to tile?
I have also read about self leveling floor materials and even picked up some Quickrete topping that states on the bag for flooor leveling, but this seems like a lot of work and not sure how level I can get it (and sure don't want to screw the floor up since it's very smooth and clean right now). Don't have a clue how to do the leveling except maybe mix a fairly thin concrete mix and let it flow and level itself but can't find instructions on this.
Any help from any tiling experts?
