Our screed mixes have a range of applications. Domestic floor finishes are commonly a 4:1 mix with 6mm polypropylene fibres and retarder added. The fibres in the mix reduce the risk of cracking while the screed sets and the retarder keeps the mix workable as it is being laid. The minimum recommended depth is 65mm and can be used to encase underfloor heating pipes to maximise the thermal mass of the floor.
