Underfloor heating screed with Grano

Tilers Forums Official Sponsors

Hi. I'm after some advice. Need to screed above my underfloor heating pipes. Some rooms have overlay boards and some rooms have new concrete and the floor will be chased/milled out for pipes to go in.

Is it possible to make screed with grano, sand, lime, concrete fibres and cement? Make a wet mix so its nice and runny and then pour that over my pipes and level out? Looking at putting a 10-15mm screed.

Any advice on what the best option is?

Quick answer is no. You need anti shrink admixtures/additives or it'll shrink and fall apart. At 15mm depth you are looking at specialised materials with high plasticity and shrinkage resistance. You could look at something like Gypsol TS-15 screed (shameless sales plug)
 
Ah ok

Ill just use this stuff which I can get locally
