Step One

All damaged plaster will be chopped away and removed to bare brick. (The height of plaster to be removed will be determined by the height of rising damp +/- 300 mm above the contaminated plaster).

Step Two

Holes will be drilled 180mm deep and 120mm apart into existing mortar between external floor level brick work, where required.

Step Three

The holes are then injected with either Dry Zone cream or Microsilon creating a new chemical dampproof course (d.p.c) the holes are then plugged.

Step Four

Treat all exposed brick work in accordance with safeguard tanking specifications (SWS slurry mixed with Bondaid plus, a waterproofing additive and bonding agent 1:4) utilizing a two coat brush application, horizontally and vertically. This will create a damproof barrier and at the same time extracting the moisture from the brick work, protecting it from any further lateral damp.

Step Five

Re-plaster areas in accordance with safeguard specification using Rendergold Gold (Salt retardant and waterproofing agent) using a mixture 3:1 by volume, sand and cement plaster mix creating further protection. Plaster work will be matched as best as possible.

Step Six

Re-painting should follow +/- 6 weeks after completion or as soon as plaster work has sufficiently dried. (To be tested with moisture meter).

Step Seven

It is always recommended to use a high grade exterior coating system (e.g. Wondercoat) that will be able to withstand the high alkalinity of such a plaster and in addition be tolerant of the moisture and chemical present in the interface.
