Product Description Renderproof is a waterproofing and plasticising cement render additive, designed for use in internal and external render coats following the insertion of a damp-proof course, such as Ultracure Dampproofing Cream. Wykamol RenderProof minimises the passage of liquid water through the pore structure of cement renders, thereby preventing the transfer of salts to the surface. Ideally the replastering should be undertaken to surface-dry walls, and a drying period of at least 14 days should be allowed between installation and re-plastering wherever possible. Renderproof is designed for use after an application of a DPC such as Ultracure Damp-proofing Cream, and areas where efflorescent salts are present and must be prevented from harming the plaster finish. Special Features Easy application Can be used on all types of masonry Reduces pore size in render to prevent the passage of water Can cover large areas in a single working application Highly concentrated: 1 part Renderproof to 24 parts water Prevents the passage of residual ground salts, which are harmful to plaster finishes Vapour permeable, allowing the walls to breathe Apply to surface-dry walls Specification Colour Pink Cure Time (2 coats or less) 24 hours Cure Time (more than 2 coats) 7-14 days before additional coats Mixing 120 litres of gauging water in dry sand per 250 Kg of cement Ready to re-plaster 14 days Application Temperature Range 5°c and 25°c Ready to Receive Finish Breathable – 14 days Non-breathable – 12 months Packaging and Size 5-litre PCR Jerry Can Storage Store off the ground and in dry, frost free conditions Shelf Life 12 months when unopened, undamaged and stored correctly Other Available Sizes Wykamol Renderproof Cement Render Additive – 25 litre
