Applying damp proof plaster to wall

Damp Proof Plaster

We have all been affected by damp at one point or another but what happens after the damp problem has been identified and suitable damp proofing has been implemented? You definitely want to make sure that your property is not affected by damp again.

There are a number of measures that you can carry out to ensure that damp does not occur again and using damp proof plaster is one of them. In this guide, we will outline how to treat damp plaster, the benefits of damp proof plaster and how technicians apply damp proof plaster.

How to Treat Damp Plaster?

Just like with any damp problem identifying the source of the problem is the key to dealing with damp plaster. Damp plaster can occur for a number of reasons: condensation, penetrating damp or rising damp. Once you have dealt with the source of moisture then it is then when replastering will need to be undertaken.

It is important to note that underneath the damp plaster there could be further problems caused by damp such as wood rot which are undetectable on the plaster surface. This is why we would recommend having a highly qualified surveyor carry out a survey to make there are no underlying problems.

If rising damp is causing the issue, then the surveyor will instruct that a damp proof course is installed prior to the replastering of the walls to protect against damp. This is where damp proof plaster can help.

The Benefits of Using Damp Proof Plaster?

The most common reason for damp proof plaster to be used is for the protection against salt contamination. Once you have had a damp proof course installed and the wall is protected from rising damp then it is important that the right type of plaster is used to prevent salts from migrating onto the wall.

Traditional plasters are not good at preventing salt contamination from appearing on the surface of the wall which is why it might be worthwhile considering using a damp proof plaster to provide extra protection against rising dampness in future. Using the correct type of damp proof plaster can also reduce the chances of mould growth and condensation as a result of raising the temperature of the wall.

If the temperature of the wall is raised to a substantial level warm moist air cannot condense onto a cold surface. Damp resistant plaster is specifically designed to be more breathable and porous which means it is can dry much faster than regular plaster.

How Damp Proof Plaster Is Applied?

Applying damp proof plaster is a 2 step process and should be carried out by a highly skilled technician. The technician will first have to remove any existing plaster that may have been contaminated as well as remove any dust from the surface.

The technician will then apply the damp proof plaster onto the walls making sure that the thickness of the coating is correct.

Should Damp Proof Plaster Be Applied at Your Property?

You might think that if your property has suffered from damp issues previously then having damp proof plaster is the best answer to stopping damp from occurring again in the future. Having damp proof plaster does not stop rising damp from causing damage to your property but it is an extra form of protection.

For example, if the damp problem occurred from a leak at the property then having damp proof plaster applied isn’t going to treat the problem on its own but fixing the leak will do this.

Damp Proof plaster should be used when you have been affected by rising damp and where it has been treated by having a damp proof course installed. We would recommend that if replastering needs to be carried out then you should always consider using a damp proof plaster.
