Wall Rendering 101: The Common Mistakes You Should Avoid

Living room wall

The walls in your home are crucial as they protect you from the outside elements and help maintain the temperature. With that said, the walls should be strong enough to support the entire structure of the house, and as the homeowner, you should do your best to maintain them in good condition. After all, a damaged wall could lead to the collapse of the entire house.

The best way to keep your walls in good condition is to ensure they’re well-rendered. Wall rendering is one of the most common practises that plasterers use in the building industry as it provides cohesion and strength to the walls. It also makes the walls look more aesthetic, improving the house’s overall appearance.

What Is Wall Rendering?

Wall rendering is a technique professional plasterers use to make walls more durable. The process involves applying a thick layer of plaster to the wall’s surface. The plaster can be applied with a trowel or a spray and is usually made from cement, lime, or gypsum.

The process of wall rendering starts with the preparation of the wall surface. The professionals will remove any existing paint or plaster on the wall. Once the wall surface is clean, the professionals will apply a layer of primer before applying the plaster. After the plaster has been applied, it will be left to dry for a few hours. Once it dries, the professionals will use the paint on top of it.

What Mistakes Are Most Frequently Made When Rendering Walls?

1. An Insufficient Ratio of Cement Rendering Material

There are instances where there’s excessive or insufficient use of rendering cement, which can cause several issues during the application. After all, cement renders must be applied with force or else they won’t adhere to the surface properly. If there’s too much water used, the render will become runny and difficult to apply. Conversely, if not enough water is used, the render will be too stiff and difficult to spread evenly.

2. Lack of Surface Preparation

If there’s something you should know about wall rendering, it’s that it always takes patience and time. This is because the plaster has to dry completely before you can start painting or wallpapering. However, some homeowners don’t heed the advice of their builders and painters, which can cause issues with the render. For example, if the render doesn’t dry properly, it can cause cracks on the surface.

3. Overuse of Sealer With Materials for Rendering

Some professional plasterers often advise that using too much sealer with a thick paste can cause cracks in the render. Sometimes, this can cause the render to peel off the wall. To avoid this, you should only use a small amount of sealer in your render.

How Expensive Are Wall Rendering Errors?

The severity of the issue will tell the response to this question. Sometimes, it can be as simple as reapplying a new coat of render to the wall. However, the damage can be so severe in other cases that you may need to replace the entire wall.

If your wall has suffered from any of the abovementioned problems, you should contact a professional rendering company to repair the damage.
