If you have a problem with rising damp on internal walls, you need to do something about it immediately. The first step to taking is removing the plaster and DPC on your internal walls and replacing them with fresh plaster and DPC. If you do not want to redecorate, then this is the time to get the damp proof membrane. This method is one of the quickest ways to solve your problem. However, it is important to remember that the treatment will not be perfect, so it is important to have the right kind of materials for the job.
How To Treat Rising Damp Patches On Internal Walls?
Rising damp affects the plaster on internal walls as the moisture in groundwater is absorbed by the plaster. The dissolved salts will cause a floury layer to appear on the wall. This is normal, as it doesn’t cause damage, but it will continue to attract moisture from the air. So, it’s crucial to take care of this problem as soon as you notice signs of it. There are two types of rising damp: penetrating damp and rising dripping.
The first type of rising damp is a problem where the groundwater contains water. This water contains salts that will erode plaster and cause mould to grow on the wall. These salts are visible as a floury crust on the wall. They are harmless and will not cause any damage to the plasterwork. However, if you can’t wait for the wall to dry completely, you may need to replaster the entire wall. Even if you can’t paint the wall because it is damp, you can seal it to prevent further problems with rising dripping.
