Damp patches on walls are a common problem in homes across the country. In many instances, it may seem like the best course of action, is to simply hide the problem and it will go away.
Unfortunately, this is rarely the case. If you just cover damp patches to hide them, you will likely see them reappearing later. Also, when they do resurface, the problem is likely to be worse.
It is possible to hide stains created by damp patches on walls. One of the most popular ways to do this, is with a good damp proof paint. However, you should try to eliminate the cause of the damp patches, rather than just painting over and hiding the problem.
5 steps to hide damp patches
- Identify the problem – Whenever you are dealing with damp, the most important thing to do, is identify the root cause of the problem. You need to find out how the damp patches are forming, so you can stop them from getting worse.
- Fix the underlying defect causing damp – This will require some detective work to identify the actual cause of the problem. Once you find the issue, it should be completely fixed before you carry out any cosmetic repairs internally.
- Dry the affected area – Once you find the cause of internal damp patches and fix the problem, you will still probably have some damp and stains on internal walls. This is because there will still be moisture trapped in the building materials, such as the bricks, mortar, and plaster.
To ensure that the damp patches don’t return, you will need to dry the area sufficiently. To do this, you can use a combination of heat and proper ventilation. A good way to speed the process up is by using a dehumidifier. Click here to learn how a dehumidifier can help
- Treat any mould and mildew – One of the most common side effects of damp is mould. If you had damp patches on your walls, there is a good chance that mould will have developed.
It is extremely important that you ensure all mould is cleaned up. It should be fully removed before you redecorate.
- Use damp proof paint – It is important to point out, damp proof paint is not a solution on its own. Even if your damp problem is small, you should always aim to fix the underlying issue causing the damp patches.
If all you do is paint over the damp, it will more than likely return later, and it could develop into a bigger problem over the long term.
By following these simple steps, you can cover up damp patches and be confident that the problem will not be returning.
After you have completed the 5 steps laid out above, you can redecorate, by applying standard emulsion or wallpaper over the damp proof paint.
