How to Identify if a Wall Needs Re-Rendering or Repair Works?

Wall rendering is a process of covering an interior or exterior wall with a thin layer of cement, sand, and water to create a smooth surface. It helps protect the walls from external elements like rain and wind while also providing insulation against fire, heat, and sound. Depending on the type of material used, wall rendering can also be decorative in nature.

Different Types of Renderings

The most common type of wall rendering is traditional plastering. This involves applying several layers of plaster (lime-based cement) on the wall and then troweling it down to get a smooth finish before painting it with a chosen colour scheme or designs. However, there are other types such as acrylic and silicone renderings, which are more durable and capable of providing higher levels of protection.

Identifying If a Wall Needs Re-Rendering or Repair Works

Sometimes walls may need to be re-rendered due to wear and tear or damage caused by external elements. Here are some signs that will help you identify if your wall needs repair works or re-rendering:

Cracks on the Surface

Cracks in walls indicate that it has weakened and is no longer providing adequate protection against the elements. It is important to repair any cracks as soon as possible before they become bigger and cause further damage.

Bubbling Paint

When paint begins to bubble up on the wall, it usually indicates that the wall is not properly sealed or the rendering material has been damaged due to moisture. It is important to remove the bubbling paint and check if any further damage needs to be done before painting again.

Discolouration

Sometimes walls may start to discolour due to age or because of a poor quality of render or lack of maintenance. If the discolouration is severe, it could indicate that there may be structural damage that needs repair and re-rendering.

Deteriorating Texture

The texture of a wall should remain consistent for many years, however, if you notice that it is starting to deteriorate – especially around certain areas – this can indicate that there may be an issue with the wall that needs to be addressed. It is important to investigate further and make any necessary repairs or re-rendering as soon as possible.

Conclusion

Identifying if a wall needs re-rendering or repair works can sometimes be tricky, but by keeping an eye out for the signs mentioned above you should be able to tell if your wall needs some attention.

If you notice any of these issues, it’s best to call in a professional who will be able to inspect your wall and provide advice on the best course of action. With the right care, your walls should remain strong and beautiful for years to come!
