NO MORE DAMP Renderproof is an additive based on an alkaline soap mixed with fatty acids, designed for use in sand/ cement, external render coats following the insertion of a chemical DPC. Efflorescent salts are
often left behind in the wall after a chemical DPC, which are harmful to the plaster finish, leaving the appearance of damp patches. A suitable replastering specification must therefore be used, including a salt inhibiting
and waterproofing product such as NO MORE DAMP Renderproof.
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.
