Rising damp on internal walls

When you notice a problem with rising damp on internal walls, you should take action as soon as possible. In many cases, the damp is caused by moisture that seeps in from groundwater and rises up the wall. During a rising cycle, the damp levels rise and the groundwater evaporates, leaving behind dissolved salts. These salts then appear on the wall in the form of a floury crust. These salts do no harm to the wall, but they draw moisture from the air. Check out – https://advanceddamp.co.uk/blog/rising-damp-patches-on-internal-walls/

What Causes Damp Walls?

If you notice rising damp on internal walls, you need to act fast. If you leave it untreated, it could lead to mould and staining of the plasterwork. Once it has dried out, it can take several months before you can paint the wall. In the worst cases, replastering the whole wall is the only option. If you do not wish to spend the money on this, then you should consider sealing the wall so that future damp does not penetrate it.

If you detect rising damp on internal walls, you will need to remove skirting boards and plaster. Remove any plaster and/or substrate that has been damaged by the rising damp. You will need to cut off any exposed bricks along the failed mortar course, and then install a physical damp-proof membrane. Once this is complete, the treatment will be effective. But you should take care when performing this procedure. You should consult a specialist to ensure that the work is done correctly.
