RenderProof is a waterproofing and plasticising, cement render additive for use following the insertion of a damp proof course and other waterproofing applications. BBA approved.
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 in external render coats following the insertion of a damp proofing course, such as Ultracure or Siliconate K.
