Product Description
Integral Waterproofer No. 2 is an additive based on an alkaline soap mixed fatty acids, designed for use in sand/cement mixes following the insertion of a chemical DPC and in other waterproofing applications. It is common in a wall suffering from rising damp for salts carried in the water to concentrate in the wall. As the wall dries out following insertion of a dampproof 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. It is essential, therefore, that a suitable re-plastering schedule is adopted following the insertion of a damp-proof course.
Integral Waterproofer No. 2, a vapour permeable replastering additive, 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 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.
Coverage
Approx. 1 litre per 25 litre gauging water (based on dry sand).
If using wet sand increase the strength of the gauging solution to ensure an addition rate of at least 1 litre No.2 per 50kg cement (approx yield 0.14m³).
