What Causes Rising Damp in Internal Walls?

Not all homes are created equal. Old buildings are designed in such a way that they must be allowed to breathe while new buildings work on a system of defensive barriers that keep moisture out. Whichever one you live in, you might have come face to face with damp at some point in your life. Below are the primary causes for rising damp inside your home.

  1. Damp Course Broken or Absent

A damp proof course is a waterproof layer that prevents water and moisture from travelling up your wall and typically absent in older buildings.

  1. Plumbing Problems

Plumbing is an important aspect of the quality of your home. Any tiny drips can cause large and even intense damp patches no matter how small. if it is regular and concentrated on the same spot, it can result in intense damp patches, that are hard to fix.

  1. Roof and Gutter Leaks

Roof leaks and leaks in the gutter will result in water flowing directly into the roof space causing damp or even worse, major damage.

  1. Condensation

Condensation is one of the most common causes of damp on internal walls. Condensation forms when warm moist air inside a room gets in contact with a cold surface like an internal wall. The warm moist air cools down and condenses back into the water. The condensation will remain on the internal wall, and create damp patches all over it.

How to Treat Damp Walls Before Painting

If you’re a homeowner you are bound to come across damp at least once in your life. And you probably know that leaving damp untreated is a big mistake and will make the situation much worse. But simply painting over the damp to hide the evidence won’t do any good either which is why you should consider damp proofing.

There are many signs that damp could be present in your walls such as peeling paint, brown stains as well as mold growth. Not only is damp an eyesore, but mould growth can also be harmful to your health. Here’s how you can damp proof your walls before painting them:

  1. Find the Damp Source

Inspect the affected and surrounding area thoroughly to determine where the damp is coming from. If damp is lower than one metre off the ground, the source might be a leaking pipe. If the damp is closer to the ceiling, you are probably faced with a roof leak.

  1. Prepare the Wall

You might have to scrape some of the paint off the wall right down to the plaster. A dark grey tinged plaster suggests an extremely wet wall. The next step is to drill holes in the wall for the moisture to escape. Give your wall enough time to dry completely. Once the wall is dry, fill the holes with exterior crack filler.

  1. Apply Damp-Proof Course

The final step is to apply the damp-proof course. This step will be repeated every 24 hours for the next few days to allow it to dry and cure. It is vital to stick to prescribed drying and curing times for maximum results.
