14 December 2020

We have all at one point or another been faced with the effects of damp. Most properties in the UK are suffering from damp problems of some description and many homeowners are looking for a long term fix. Damp proof paint is a type of preventive measure that stops the resurgence of damp returning and we have been asked the question many times by customers “does damp proof paint actually work? This is a difficult question to answer which we will explain later in this article.

This article will explain what damp proof paint is, how it works and if it is actually a good solution to solving damp problems.

What is a Damp Proof Paint and How Does it Work?

So, what is a damp proof paint? Basically, It is a water reactive agent that that stops damp resurfacing onto your walls. Damp proof paint is a strong resistant paint which can be ideal when property owners live in homes where there tends to be a lot of moisture.

This type of paint is easier to maintain than normal paint as it can be washed and wiped. Costs can also be saved by the property owner due to the long term protection of the damp proof paint as it contains a powerful polymer (it can be longer lasting when compared to ordinary paint).

The main benefit of using a damp proof paint is that it will make your home more appealing if you are looking to sell or rent out your property.

If the rooms in your house are suffering from dampness then using a damp proof paint will ensure that they will appear fresher, brighter and more importantly damp free. If a potential buyer or tenant sees any damp in the house, then this will instantly put them off from buying or renting.

Problems with Damp Proof Paint?

It is important to note that while damp proof paint has its advantages, there are some issues you need to be aware of regarding the use of damp proof paint. Firstly, if damp is coming through your walls as a result of water penetration caused by structural defects then damp-proof paint will not stop the damp problem but only mask it.

Damp-proof paint only stops moisture on the surface meaning that fixing the structural fault would be the only way of sorting out the damp issue for good.

The other issue people tend to have with damp proof paint are as a result of when it is not applied onto the walls properly. Before applying the paint, the surface must be free from any previous coating of paint.

For the damp proof paint to work effectively you should also make sure that any dirt and debris is removed from the surface. One other point to note is that there should not be any surface water on the wall during the applying paint process.

So, Does Using a Damp Proof Paint Actually Work?

We have explained the advantages and disadvantages of using damp proof paint to stop against damp and if applied correctly then yes it does work but there are cautions to be aware of.

If the damp remerges then it is likely that the cause of the damp problem has originated outside of the property e.g. problems with guttering or a damaged damp proof course. If these issues are not fixed first, then the damp proof paint will not work and will only mask the issue for a short period of time.

If you are struggling to find the root cause of the damp problem, then contacting a damp proofing specialist should be the first port of call to examine where the damp problem is coming from and determine what type of damp problem it is.
