The Importance of Replastering After Damp Proofing

A very common question that we get asked is – why is replastering necessary after damp proofing? The answer is that replastering is fundamental because of the salt contamination in the old plaster. Many people believe that once a new damp proof course has been installed, all of your damp problems will have been dealt with, and once the wall is dried out, all signs of damp will disappear. 

However, unfortunately, this is not the case – especially if there are hygroscopic salts trapped in your wall and plaster. Hygroscopic salts will prevent your existing wall plaster from properly drying out. As a result, it’ll be necessary to replace it with a salt retardant render, in order to achieve a dry internal finish. 

In this post, we take a closer look at replastering after damp proofing, outlining why it’s important and what you need to know about the process. Keep reading to learn more about this, and if you need to replaster your walls – get in touch with Kenwood PLC today to find out how we can assist you.

Why Hygroscopic Salts Can’t Be Left in Your Plaster

Hygroscopic salts cannot be allowed to stay in your plaster. Simply put, they’re a problem for plaster as they absorb moisture from the air, and as a result, this can create damp patches on your walls – even when you have a damp proof course installed. 

This process is widely known as hygroscopic dampness, which is a different type of damp issue compared with rising damp. It can lead to the growth of mould and mildew, which can cause health problems and structural damage to a building. 

In order to prevent this from happening, it is essential that you do not leave hygroscopic salts in your plaster after the damp proof course has been installed. Replacement with a salt retardant render like Kenwood Waterproof Rendering System is vital for providing a dry internal finish.

What Does Replastering Involve?

We provide specialist plastering after damp proofing; this is an integral part of rising dampness treatment. Our specialists are experts in replastering damp walls and we can ensure your property is left damp proof and suitably rendered. 

During the replastering process, we use our Kenwood Premix Waterproof Rendering System, which is factory produced and consists of specially blended dried sands, cement, lime, aggregates and high performance waterproofing additives, along with polypropylene fibres for decreasing shrinkage.

We weigh and mix these materials using a computer controlled system with rigorous quality control procedures. Our technical and advanced method means that we can deliver the most optimal plastering solution for every single client; it sets us apart from our competitors.

How Much Does Replastering Cost?

At Kenwood PLC, we offer a fixed price for waterproof rendering and replastering services, which is unlike any other company. This means that no matter how thick the plaster is, the price remains the same even after it is taken off. We never charge extra for thicker plaster.

When you’re comparing quotations, it is important to note that the majority of companies offer an estimated cost for replastering damp walls – usually made on the assumption that the plaster is not thicker than a certain thickness such as 18-25mm. These companies will make an additional charge if the plaster is found to exceed this thickness when it’s taken off the wall.
