Whether you’re a homeowner or a commercial property owner, cracked render can be one of the most alarming issues. Not only does it make your property look unsightly, but it can also cause further damage if not addressed correctly. One of the most common worries associated with cracked render is whether or not it will lead to damp problems.
At Plymouth Plastering Pros, we know that cracked render may lead to damp walls. It is because damaged or cracked render allows rainwater to seep into the wall, which can cause dampness and mould growth.
Fortunately, our team of experts has years of experience in diagnosing and repairing crack render problems. We use only high-quality materials to ensure your rendering looks great and lasts for years. Our services include everything from minor repairs to full-scale re-rendering projects.
What is Damp?
Cracked render can indeed cause dampness in buildings. Render is the coating applied to exterior walls that protect against weathering and other damage. When it cracks, water can seep through the gaps and penetrate the interior of the building, causing dampness.
Dampness caused by cracked render can lead to problems such as mould growth, musty odours, peeling wallpaper or paint, and even structural damage if left untreated.
How Does Cracked Render Cause Damp?
Cracks in the render can lead to moisture penetration, dampening the walls. Moisture seeps into the wall through hairline cracks and gets trapped between the layers of render and masonry. Gaps in renders facilitate this process, allowing water to penetrate more easily.
The cracked render also compromises waterproofing, as it can no longer effectively protect exterior walls from water damage. In addition, broken or damaged rendering allows excess water to infiltrate behind the rendered surface, resulting in damp patches that are visible internally.
Rendering Techniques to Prevent Damp
Several rendering techniques can be used to prevent dampness. One of these is a waterproof render specifically designed to repel water and prevent it from penetrating the walls. Another method is applying a silicone-based sealant over existing render cracks, sealing them from further damage.
Finally, fixing any underlying issues, such as damaged guttering or roofing, is essential before rendering work occurs. Doing so reduces the risk of water penetrating your walls via any structural weaknesses outside your home. Overall these techniques will help protect your home against dampness caused by cracked rendering.
Any crack or imperfection in a building’s exterior can lead to moisture infiltration. For example, a cracked render may allow water to penetrate the surface of the building and seep into the underlying structure, which could ultimately result in dampness and other related issues.
Prevention is always better than cure when maintaining your home’s structural integrity. However, taking proactive steps towards addressing potential issues early on can avoid costly repairs and ensure your property remains safe and secure for years.
