Features and Benefits
RonaScreed SBR is an SBR screed admixture for site batched screeding mortars and fine concretes. The mix design for each is RonaScreed SBR screed admixture, cement, medium grade sharp sand, aggregate as determined by the mix design, plus water. The components are measured by weight or by volume on-site and mixed using forced action mixer to form the screed.
A mixture of RonaScreed SBR and cement achieves monolithic adhesion to correctly prepared concrete or screeds.
RonaScreed SBR screeds are used to lay new screeds and toppings as thin as 10mm bonded. The cured mortar bonds securely to suitably prepared surfaces and are water-resistant.
RonaScreed 8 Day Overlay Fast Drying Screed (formerly Uniscreed Standard) is so called because it is a fast-drying screed additive which enables a 50mm thickness of 3:1 sand/ cement screed to be overl ...Read more
Aggregate is usually 0–4 mm and is mixed with cement in the ratio of 1:3 or 1:4 cement to sand, depending on strength requirements and drying requirements. For total screed thicknesses in excess of 50 ...Read more
