It's never a good sign if you discover moisture stains or mould on your interior walls. Peeling wallpaper can also be a sign of damp interior walls. That's not only detrimental to your home, it's also unhealthy. That’s why it’s important to treat a damp interior wall. And you don’t necessarily need to call in a professional. So how do you treat a damp interior wall? Read on to find out.

Treating rising damp on interior walls

Rising damp is a common cause of damp interior walls. Moisture in the ground can enter your home through an ageing foundation. This type of damp is most noticeable near the bottom of the wall, where you may see moisture stains or wallpaper starting to come loose. So how do you treat rising damp on interior walls? There are two effective ways to tackle the problem.

Injecting damp interior walls

A relatively simple way to tackle rising damp is to inject the wall with a gel or liquid. Aquaplan's Wall Protect Inject Liquid and Wall Protect Inject Cream allow you to create a horizontal moisture barrier in the wall. To do this, you drill holes in the wall at regular intervals, allowing the product to penetrate and spread through the masonry.

Treating rising damp on interior walls with DPC Waterproof Membrane

You can also use Aquaplan's DPC Waterproof Membrane. This waterproof membrane is installed between layers of masonry. Naturally, this solution involves quite a bit of cutting and chiselling. A damp-proof layer is normally installed when a new house is built, so using a DPC Waterproof Membrane to treat rising damp in an existing building is not an easy job. For an existing building, it is usually easier to inject the wall. However, if you are planning a major renovation, installing a DPC Waterproof Membrane is a good way to prevent rising damp from becoming a problem in the first place.

Treating a damp interior wall caused by condensation

In addition to rising or penetrating damp, you may also suffer from damp interior walls caused by condensation. This happens when the walls in a damp room feel cold. Moisture in the air condenses on the cold wall, leaving it clammy and damp. This creates an unpleasant indoor environment. Damp rooms such as bathrooms are particularly prone to condensation. So how do you treat a damp interior wall if the problem is caused by condensation? It’s simple: apply Wall Protect Condensation Stop (previously: Wall Protect Condens Stop). This wall and ceiling coating has an insulating effect, helping to make the wall feel less cold. Moisture is less likely to condense on the surface, helping you tackle damp and mould caused by condensation. Treating a damp interior wall doesn't have to be difficult.
