Rendertite is a liquid admixture designed for use in reducing water absorption and makes cement mixes less permeable. Due to its strong air entraining plasticiser, the water cement ratio is much lower for a similar workability.
Rendertite is suitable for use in rendering finishes and pointing mortars.
It is also used in reconstructed stone and non-structural concrete members – particularly valuable in
Rendertite is ready for use and is added to the mix at the selected dosage rate.
Mix designs will depend on factors such as location and sand gradeing.
Refer to local standards and codes of practice for guidance.
0.5 to 1.0 litre per 50 kg cement
Rendertite contains a highly hydrophobic material which is dispersed throughout the mix and thus repels moisture. Rendertite also entrains air and this reduces capillary and water channel development, thus ensuring greatly increased water resistance and resistance to frost attack. In addition, due to its plasticising action, a significant reduction in water content is achievable.
Rendertite slightly retards the mix, e.g. a 3:1 sand/cement mix will be retarded by about 15 minutes.
