Tiling on underfloor heating liquid screed

[Rudie]

Hi I am looking to start tiling on a new project. Have installed underfloor heating pipe work and had liquid screed poured on about 3 months ago. Heating working fine. I have had the floor polished as well.
I have brought proflex so s1 bags to lay the tiles and have brought durables rolls.

So my question is, I have to prime the floor, but which primer is best for the floor I have?

Also what adhesive do I use to fix the durabase to the floor? Not sure if I can use the proflex?

Wana make sure I get this right first time!

Thanks in advance.

I used mapei primer G (a few coats) for my liquid screed floor, I then used flexible semi rapid tile adhesive to stick the mat (Dural CI++ crack mat) to the floor. Used a small notched trowel.

This is the tile adhesive I used:

Rocatex

I used the same tile adhesive for the tiles to the mat, just used a very large notch trowel, 20x10mm for the tiles, 600mm stone.

Good luck, take your time.

Thanks mr chibs. I will get the same primer from local store. I will try the proflex to stick the mat to the floor and see how it goes.

hi, what size trowel notch did you use for sticking the matt down to the floor?

Think I used a 6mm, you can use smaller.
