Why Replastering is Key to Effective Damp Proofing
When it comes to damp proofing your home, many homeowners focus on installing a damp proof course to prevent moisture from rising through the walls. However, a crucial but often overlooked part of the damp proofing process is replastering. Replastering is essential to ensure that the treatment is successful and that your walls are left dry and protected from future moisture related issues. Without this step, even a well installed damp proof course may not provide the long term results you expect. In this post we share all you need to know about replastering; why it’s important, what it does, and more about our replastering process at Kenwood PLC.
What Is Replastering?
Replastering is the process of removing old, moisture damaged plaster and applying a new layer that is specifically designed to resist moisture. This is a key step after a damp proof course has been installed, as rising damp often brings soluble salts into the walls. These salts become embedded in the existing plaster, which can then prevent the walls from drying out properly. If left untreated, the salts can continue to attract moisture, causing ongoing damp problems.
The new plaster used during replastering is typically a specialist salt retardant render that helps prevent moisture from penetrating the wall. This type of plaster ensures that the wall can dry out fully, free from any salts or contaminants. By removing the old plaster and applying a fresh, protective layer, the wall is not only restored in appearance but also protected from future moisture issues.
Why Is Replastering Important?
Replastering plays a key role in ensuring the long term success of any damp proofing system. When rising damp brings hygroscopic salts into the plaster, it can cause the wall to continue absorbing moisture even after the damp proof course has been installed. Without replacing the old plaster, you risk recurring damp problems, including discolouration, crumbling plaster, and damage to internal finishes.
The application of a salt retardant render during replastering creates a barrier that prevents moisture from being drawn back into the wall. This protective layer is vital for ensuring that the damp proof course can work effectively, allowing the wall to remain dry and structurally sound. Without proper replastering, even the best damp proofing systems may not provide the long lasting protection your home needs.
Our Replastering Process
We pride ourselves on offering a highly technical and reliable replastering service through our Premix Waterproof Rendering System. This system is factory produced and consists of a carefully blended mixture of dried sands, cement, lime, aggregates, and high performance waterproofing additives. These materials are combined with polypropylene fibres to reduce shrinkage, ensuring a durable and long lasting finish.
What sets us apart from other companies is our rigorous computer controlled system, which guarantees that every batch of render is perfectly mixed to ensure consistency. This method is far superior to traditional hand mixed renders, which are often measured by volume rather than weight, leading to variability in quality. Our pre-mixed rendering solution ensures that each application is of the highest standard, designed to complement our damp proofing systems and prevent future moisture issues.
Many traditional renders used in damp proofing are hand mixed on site, which can lead to inconsistencies in the quality of the plaster. This process, often done by eye and measured by volume, increases the risk of poorly batched renders that may not effectively protect your walls. These substandard renders are one of the primary reasons for the failure of damp treatments, leaving homeowners with recurring problems.
Our Premix Waterproof Rendering System eliminates this risk by providing perfectly batched renders every time. Since our system is specifically designed for use on damp walls, it significantly reduces the chances of future problems, such as flaking or crumbling plaster. Our rendering system is also applied by our own skilled operatives, ensuring complete quality control at every stage of the process. This attention to detail ensures that your damp proofing solution remains effective for years to come, providing you with peace of mind.
