What is Render?

Render is a protective and decorative coating applied to the exterior walls of buildings. It serves multiple purposes, including enhancing aesthetics, providing insulation, and protecting the underlying structure from weather damage. However, if not applied correctly or maintained, render can develop defects that may lead to damp problems.

Cracks in the render can occur due to settling, temperature fluctuations, or poor application. These cracks create openings for moisture to penetrate, allowing water to seep behind the render and into the walls, leading to damp and mold growth.

Blistering occurs when moisture gets trapped under the render. As pressure builds, the render may start to bubble or peel away from the wall. This not only compromises the appearance but also allows further moisture ingress, exacerbating damp issues.

If the render does not adhere properly to the underlying surface, it can begin to detach over time. This can create gaps that allow water to enter, leading to damp spots and potential structural damage.

Certain types of render may not be breathable, trapping moisture within the wall. This trapped moisture can promote the growth of mold and mildew, leading to health issues and damage to the building materials.

Improperly sealed joints between render and other materials, such as windows and doors, can allow water to penetrate. This can create damp areas inside the walls, especially during heavy rainfall.

Over time, render can deteriorate due to exposure to the elements. This weathering can create weak spots that are vulnerable to moisture penetration, increasing the risk of damp.

Regular inspection and maintenance of your render can help identify and address defects before they lead to serious damp issues. Keeping an eye out for cracks, peeling, and discoloration can save you from costly repairs in the long run.

Defects in render can significantly impact the integrity of your home and lead to damp issues that affect both your property and your health. By understanding how these defects occur and the importance of proper maintenance, you can protect your home from the detrimental effects of damp.
