Admixture for thin bonded, floating & unbonded screeds


Ronafix SBR is an admixture that increases the physical properties of site batched sand and cement screeds. Screeds containing Ronafix SBR will have enhanced strengths which allow for thin section application and early access. The mix design for each is Ronafix SBR, 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 to form the screed.


Bonded screeds are used with a primer of Ronafix SBR and cement which achieves monolithic adhesion to correctly prepared concrete.


Ronafix SBR screeds are used to lay new screeds and toppings as thin as 10mm bonded or 35mm unbonded and floating. The cured mortar bonds securely to suitably prepared surfaces and is water resistant.
