… And why can’t damp plaster be left to simply dry out? These are questions that get asked a lot by our customers who need a damp plaster treatment on their wall. That is because of the amount of mess it creates at the offset whilst treating damp plaster. This one thing can be enough to put a customer off dealing with the problem.
Surely you simply inject the wall with damp proofing fluid and then the water will just dry up, right?… WRONG!
Here Cannon Contractors will explain why it is key to remove the damp plaster whilst also treating the damp brickwork underneath to gain only the best results for a damp free home.
The damp plaster will need to be removed to eradicate any trapped moisture within the substrate. The damp plaster requires hacking off to a height of 1.2 metres because water can rise to this level. The best solution is to chemically inject the walls with a dryzone injection fluid. Then the internal side of the wall is ready to be tanked. This works like a swimming pool effect, holding any water out of the internal plaster finish. Before hacking off damp plaster an experienced damp proof surveyor will first find out how far the moisture has travelled up the wall. The surveyor will probe the wall in an upward fashion and may well find 1 metre is an adequate level to remove plaster. This height will most likely vary in some areas and will not uniformed in its pattern.
Next, the new plaster work is fitted and left to thoroughly dry for the recommended period. Then the walls are ready to be redecorated with no chance of the damp reappearing. After years of experience using this method Cannon Contractors know that (if installed correctly!) this is the best, and only way to keep damp at bay. So, as for the damp plastering, yes it is the key element, and MUST be removed if your damp proof treatment is to be successful. Without this the Damp Proof course is an absolute waste of time.
We hope we have answered this common question as to why new plaster is a must with damp courses. If you pick the company wisely and the work is done correctly, then you can rest at ease in the knowledge that you will be damp free and with a guarantee from a reputable company.
