2. General Preparation

Masonry joints should be raked out and all surfaces thoroughly cleaned to remove dust or other friable material. All traces of previous gypsum plaster must be removed. Any organic matter (including timber fixings) must be removed and, where appropriate fixing points which necessitate cutting into the background prepared. High suction surfaces should be thoroughly wetted or 'Techno' SBR primer used (details available on request). Smooth dense surfaces must be hacked to provide a mechanical key or SBR bonding primer used.

Cement-based plastering systems should not be applied to painted surfaces or those coated with bituminous products. Replastering following the insertion of a d.p.c. should be deferred for at least 14 days and any salt efflorescence removed before proceeding as above.

After the insertion of a d.p.c. the residual water in the wall must evaporate before normal dry conditions are achieved. The time will vary according to the amount of water present and the thickness of the wall but one month per 25 mm thickness of wall is quoted as a guideline.

Finishing – Redecoration: After allowing the backing coat to set and dry (minimum 24 hours, preferably longer, especially under adverse curing conditions) the finishing plaster should be applied at 1.5-3 mm thickness. Suitable finishes include Thistle Multi-finish, Limelite Finishing etc. Where scratch coats are left as a finish a high quality wood float finish may be used.

All replacement skirtings etc. should be either pre-treated or treated with a suitable preservative, and primed on the back before being fitted, using rust proof screws and plastic plugs, or a suitable adhesive. Redecoration should be regarded as being temporary until the wall has dried out. A thin application of matt emulsion paint is
recommended as a temporary measure.

It needs an initial source of moisture but it can then spread to attack adjacent dry wood and can travel through masonry.   RegencyHDT
