Screeding porch

James289324890 said:

I have a porch floor that's been taken back to the concrete slab, which is around 70mm lower than the other floors. I'm intending to tile it, and the tiles and adhesive will be around 13mm in height.

This means I'll have to raise the height of the floor around 50 to 60mm prior to tiling.

From what I've read this seems to be a bit too thick for a bonded sand/cement screed, but too thin for an unbonded sand/cement screed.

Wondering what the best way of going about things would be. I was thinking maybe instead of making the whole height with sand/cement screed, I could just use self leveller and then find some other way of raising the height, like plywood.

Thanks

Screed it, then you could always throw a bag or 2 of slc over the top to get a nice flat surface for tiling.

Screeds are supposed to be a nice flat surface for tiling mate.
