REPLASTERING

Where plaster has to be renewed because of contamination with hygroscopic salts, it is vital that a special salt retardant additive is used to hold back any residual salts while still allowing the passage of water vapour.

Standard plasters such as Carlite should not be used as many have hygroscopic content and failure to follow this instruction is the most common cause of continuing wall dampness after a remedial dpc has been installed.

The recommended method is illustrated below:

Where necessary, we can either undertake the re-plastering as part of the remedial damp proofing contract or supply our special DryWall Salt Retardant additive for the client’s plasterer to use in a sand and cement render.

Where there are steps in floor level, we recommend applying a waterproof slurry coat to prevent moisture ingress through masonry below the level of the remedial damp proof course.

Arrange a Replastering Survey

I'm sure that businesses come and go in your trade but your Company has been in existence for a long time. My recent experience demonstrates why this is the case.

Our 30 year guarantee had almost expired when we recently discovered woodworm infestation in the previously treated roofing joists. I understood why you wanted to charge the refundable fee for the survey and took the risk in requesting it. However, I anticipated that you would attempt to "wriggle" out of the guarantee and was ready for an argument with your surveyor. My cynicism was totally unfounded. Your surveyor efficiently identified the problem and confirmed that the area would be re-treated - I didn't have to say anything. Your operative subsequently did the treatment work efficiently and with a high standard of housekeeping. In both cases, they were friendly and courteous.

In effect, I'm impressed with the professional and ethical characteristics of your Company and I'm extremely pleased that I engaged you.

Why do I have to have the plaster removed when you install a new damp proof course ? It looks sound enough.

I have recently had a dpc installed by your company. I gave the information on replastering to a recommend plasterer, but the plaster covers the holes were the dpc was inserted with a gap between the plaster and the wood floor. Is this correct ?

Recently when I had work done on my damp problem, after taking the plaster off the walls, no time was allowed for the bricks to dry out before putting the new plaster on, then inject the chemicals.Should bricks have dried out before adding new plaster.

I've recently had a damp proof course, as well as re-plastering with the salt-retardant plaster (by yourselves). I was advised that I can paint the walls with a paint that allows moisture to evaporate from the brick, can you advise on a brand?

I had a dpc course done in 2004, the plaster was replaced but mould has now started to come back through how do i make sure this is a fault in the dpc and not a fault with the re-plastering
