After the injection of a Chemical DPC (Cream or Fluid), re-plastering with an appropriate salt resistant product, such as a sand / cement mix containing a suitable Render Additive, is essential to prevent further damage to the plaster finish.
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 re-plastering specification must therefore be used, including a salt inhibiting and waterproofing product such as RenderProof.
