Screed
Not all flowable screeds are Calcium Sulphate . Many are based on cement with the use of a copolymer which produces a strong, hardwearing surface similar to concrete.
Cementitious screeds based on advanced technology are also now available that incorporate all of the benefits of a semi-dry screed such as laying to falls or creating steps in doorways to accommodate different floor finishes whilst also incorporating many of the benefits of flow applied screeds. Retanol Xtreme that is BREEAM and TÜV Rheinland certified (zero harmful content) requires no curing under polythene, dries to under 75%RH in 3-4 days, can be laid from 15mm thick bonded and 35mm thick floating, is suitable for wet or dry, internal or external conditions. It dries uniformly throughout the body of the screed rather than from the top down so no cracking or curling and no requirement for fibre reinforcement. It is also ideal for UFH systems as it can be applied at just 30mm cover and commissioning can take place after just 24 hours with a 60% improvement in conductivity over traditional screed systems. Heavy Duty versions are available but even the standard version achieves compressive strengths of up to 50N/mm².
