Wet UFH what screed would you use?

[Donnie Ban]

4 years ago my wife and I put down insulation, laid the pipes and did all the heating including the wiring of the manifold and programmable roomstat in each room, with help we DIY mixed 4 to 1 crusher dust or quarry dust with loose glass fibres, bought a cheap electric vibrating poker on ebay, that meant the screed seeped under the pipes as there where no stones. I did 5 rooms individually, 1 lounge 1 bedroom 1 bathroom 1 kitchen 1 u/t and toilet. I then covered each room individually with tarpaulins so the cement would cure instead of dry, left them for the recommended weeks plus an extra week, tiled them, put heating on as recommended and 4 years later as there is not a crack to be seen anywhere. I am only a diyer and never tackled anything like this before, so if you think you can do it give it a go, but make sure you read up on it first
