Renderguard Gold
Renderguard Gold is a high-specification plaster additive that forms an integral part of the Safeguard Damp-proofing System (BBA Certificate Number 97/3363).
Following the installation of a remedial DPC (using Dryzone Damp-Proofing Cream or Dryrod Damp-Proofing Rods) correct re-plastering is of the utmost importance. Even though the DPC is effective, hygroscopic salts introduced by the rising damp may cause moisture to be attracted to the wall. This causes further dampness and decorative spoiling, giving the impression that the DPC has not been successful. It is for this reason that re-plastering following the installation of a remedial DPC 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.
When used as an additive to a 3:1 sand-cement render, Renderguard Gold will fulfil these requirements provided that the specification is strictly adhered to.
Where the use of a hard sand/cement render is not desirable, the Dryzone System fast-track replastering system should be considered. In many situations this system can allow rising damp treatment and redecoration to take place the same day.
The use of Vandex Refurbishment Plaster should also be considered.
