Levelling floor area. What to use?

modelreject

I have a small area on a floor that I need to level for tiling. The area is 60cm x 124cm. From the back it slopes from floor level to 2.5 cm below floor level at the front.

Would I just use normal cement as it is such a small area? Whatever I put down, the thinness towards the back, will this cause issues? Could I just pile thinset on a bit thicker at the deeper end?

Many thanks.

F Ball green bag screed and 128 latex mixing liquid and aggregate chips, make up a fairly stiff mix. you might need to go over the edge if the aggregate is coarse after main fill dries, but if you are fitting tiles with cement adhesive it maybe will take up the difference

It doesn't need to be absolutely level for tiling but it does need to be flat.

Screed it to take out the slope but don't take the screed to where it is at floor level. Stop so that you have around an eighth left all over to bring it up to approx level. Then use an SLC to finish off then tile over that.

Yes if you try and screed it level. It will be far too thin at the back and won't take. The SLC

No. Thinset? You've been reading too many US websites on tiling.

It will depend on the tiles. Small tiles can tolerate a moderate curve to the floor, large tiles are less tolerant. It is obvious if you think about it. There is information somewhere which tells you how much variation over the width of the tile is tolerable, perhaps on the adhesive datasheet.

Be careful if you have a door. If the floor slopes downwards towards the door opening, the door opens into the room, then you won't be able to open the door unless you remove a large chunk from the bottom of the door (which looks naff) or use rising butt hinges. If it is a fire door, then I don't think you can get rising butt hinges, and you don't want a large gap.
