Renderproof is a BBA Approved waterproofing and plasticising additive designed for use in internal and external render/plaster coats to damp proof and salt protect the plaster finish. Ideal for use following the insertion of a damp proofing course, such as Ultracure or Triton. 
 
Wykamol Renderproof minimises the passage of liquid water through the pore structure of plasters and 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.
