Brunopel IWP is a BBA Approved additive based on an alkaline soap of mixed fatty acids, designed for use in sand/cement mixes following the insertion of a chemical DPC.
It is common in a wall suffering from rising damp for salts carried in water to concentrate in the wall. As the wall dries out following insertion of a damp-proof course these salts may be deposited on or near the surface and can give rise to efflorescence.
If the salts are hygroscopic, damp patches may also develop when the ambient humidity is high unless steps are taken to ameliorate the problems. Failure to do so may allow or give rise to other dampness problems of a more persistent nature. It is essential, therefore that a suitable re-plastering schedule if adopted following the insertion of a damp-proof course.
Brunopel IWP is designed to minimise the passage of liquid water through the pore structure of cement renders, thereby preventing the transfer of salts to the surface. Re-plastering should be carried out as long as possible after the insertion of the remedial damp-proof course, but in any case a drying period of at least 14 days should be allowed between installation and re-plastering wherever possible.
