Description
RonaScreed SBR
RonaScreed SBR Admixture screeds and toppings may be laid bonded as thin as 10mm. The cured mortar bonds securely to suitably prepared and primed surfaces and is water resistant. Bonded screeds are primed with a mixture of RonaScreed SBR and cement, which achieves monolithic adhesion to correctly prepared concrete or screeds of adequate strength for adhesion of a high strength topping.
The mix design for each is SBR admixture, cement, medium grade sharp sand, aggregate as determined by the mix design, plus water. The components are measured by weight or by volume (batch boxes only) on site and mixed using forced action mixer.
Using the Surface
SBR screeds and toppings can typically receive foot traffic after 24 hours and heavy traffic after 3-5 days at 20°C. Allow more time in cold conditions.
