Permaproof Waterproofer is an all-purpose waterproofer, mortar plasticiser and salt inhibitor specifically suited for use with sand/cement render mixes particularly after the insertion of a chemical DPC and in other waterproofing applications.
It is common for walls that have suffered from rising damp to be contaminated with high levels of salts. After the insertion of a new damp proof course the wall will start to dry out, as the wall does so these salts may be deposited on or near the surface and give rise to efflorescence. If the salts are hygroscopic, damp patches may also develop when the ambient humidity is high. It is essential that the re-plastering specification is strictly adhered to and that the plasterer carrying out the work is made aware of the importance of the re-plastering being carried out to specification in conjunction with the insertion of the Chemical DPC.
Permaproof Waterproofer is designed to minimise the passage of liquid water through the pore structure of cementitious renders, thereby preventing the passage of salts to the surface in the drying out period.
Re-plastering should be carried out as long as possible after the insertion of a remedial damp-proof course. Ideally the new plaster should be applied to surface-dry walls, but in any case a drying period of at least 14 days should be allowed between installation and re-plastering wherever possible.

Great valueThe Render Additive is great value for money, after having shopped around i found this to be the best priced product and after using it i wasn't dissapointed on the quality.
