Renderpel salt inhibitor and waterproofing render additive is designed to be added to cement/sand mixes used when replastering following the insertion of a remedial damp-proof course such as Dryzone silicone damp proof injection cream.
Correct replastering is of the utmost importance. Even though the damp-proof course is effective, hygroscopic salts introduced by rising damp may cause moisture to be attracted to the wall. This causes further dampness and decorative spoiling, giving the impression that the damp-proof course has not been successful. It is for this reason that replastering following the installation of a remedial damp-proof course must perform two functions:
- It must prevent the passage of residual moisture reaching the decorative surface during the drying process.
- It must prevent the passage of hygroscopic salts from the underlying masonry to the new decorative surface in order to prevent further spoiling.
- Coverage: 1 litre of concentrate is sufficient for 7 square metres of render at 12mm thickness.
