Hey guys
How thin can you go with an underfloor heating screed bonded to a concrete slab?
I've got 28-30mm of flooring to raise.
I know that a normal sand cement screed will curl but I've read that screeds reinforced with polypropylene fibres can go as thin as 25mm.
Does anybody have any experience with this?
Please can somebody give me any advice?
I know Mapei renovation screed will work, but its expensive and I already have lots of sand and cement that I can use, will just need to buy a small bag of polypropylene fibres.
From bottom to top this is what my floor looks like:
100mm PIR
100mm concrete
16mm UFH pipe
28mm screed (including UFH pipes)
Porcelain tiles
My concrete has been laid. Just need to figure out what to do next before I can put down pipes + screed.
Thanks in advance
