Sloping kitchen floor

ag1975 · Mar 5, 2013

I'll be tiling a mates kitchen floor in a couple of weeks and not too sure how to go about levelling the kitchen floor. The floor has an undulating slope and probably has a difference of at least 2 inches between high and low points. I've never used SLC before and I believe it should only be used to level out a difference of no more then 5mm, is that right???

What can I do to level the floor? I could get busy with a hammer and chisel i guess but looks like a lot of hard work. Are there any other ways??

You can get slc to go to that but what are the implications re doors units white goods, how big / long is the floor, if it's flat and in use will your mate accept it tiled as is, if not it's a whole lot of work.

The floor is about 6 m2 and slopes away from the units so not a problem with those. It's a little bit undulating but slopes mainly into one corner (bottom right) from its furthest corner (top left).

The floor isn't flat enough to tile on.

I understand, but there's flat and there's level, if he wants level of course it can be done, without seeing the job it's nigh on impossible to say what ALL the problems may be, you can get slc to go up to 50mm in one hit, expensive way to go, if your going to level it then maybe look at fixing a backerboard.

tilemaster levellflex can go up to 50mm thickness in one hit

So would you use shims with the backerboard?

Hi, there are a number of good fiber re-inforced levelling screeds designed exactly for your kind of job, Mapei, Ardex, Kerakoll to name but 3, these companies all have good tech back up for advice.
