There is a lot of talk online about damp proof paint - some claim it’s a fantastic product, while others say it’s a con!

In reality, damp proofing paint does have its uses but is not the solution to most damp problems. There is no substitute for products like DPM underlays and DPCs!

This article looks at potential uses for damp proofing paint and when you should stay clear away.

What is Damp Proofing Paint?

Damp proofing paint appears on the surface a lot like traditional wall paint. However, it is specially designed to help protect interior walls from problems with damp.

Damp proofing paint works thanks to an agent in the mixture, activated when it comes into contact with water. Essentially, it helps combat residual surface moisture on the wall, which can lead to problems such as discolouring.

When to Use Damp Proofing Paint

Damp proofing paint is an effective way of helping to combat issues relating specifically to internal damp. When applied properly, it provides an extra layer of protection and is easy to maintain.

Examples of situations where using damp proof paint could be a good option include:

  • To provide another layer of protection for painting against an already protected surface.
  • Covering up or protecting from damp stains after fixing the cause of damp.

To apply damp proofing paint, the wall needs to be cleared of any previous coatings, including paints. All surface water needs to be removed beforehand, also.

When Not to Use Damp Proofing Paint

As mentioned, damp proofing paint is designed to help prevent damp appearing against internal walls. This paint doesn’t provide a remedy to more significant damp issues and should never be considered on its own if the problem is more serious.

If there is an issue inside the wall or externally causing damp, this will need a dedicated fix. You can then use damp proofing paint to provide another layer of protection and assurance once the larger issue has been remedied.

How to Protect from Damp

There are many ways to protect a building from damp, and the most effective method of prevention is ensuring all walls and roofs are adequately protected when built.

Damp proof membranes and damp proof courses are two of the most effective materials for protecting buildings from rising damp. You should always consider including these and similar products in your build to help provide long-term structural protection from damp.
