Render walls can look quite stunning when they are coated in a smooth layer of velvety soft paint. Even though render walls can last many years, they might show some signs of wear after some time. It is always best to get render issues restored or they can become a lot worse over time.
Let’s take a look at some of the most common render problems your walls might present and the best ways to get these issues restored.
Small Cracks
Small cracks on your smooth wall might not seem like much of an issue but it is best to get these tiny cracks patched up as soon as you can. These small openings can allow moisture to saturate through. When moisture accumulates between the rendering and the wall, mould can start to grow and the surrounding materials can weaken. Over time, this can cause the crack to widen or chunks of render can start breaking away from the wall.
The best way to deal with hairline or small cracks in your wall is by filling them out with an acrylic-based sealant or a suitable render repair mix. The filled-out portions are then sanded down until the wall surface is perfectly smooth and the wall can be re-painted to conceal the area.
Cluster Cracks
Over time, more and more cracks may show up on your walls. A grouping of small cracks can be caused by moisture buildup, thermal expansion, and contraction, or by the general decay of the materials.
These types of cracks can be a bit difficult to restore because simply filling them out with a render repair mix can leave behind some markings. The best way to restore cluster cracks in a wall area is by filling out all the gaps and adding a layer of render repair mixture over the entire area. When you smooth out the edging around the patched area, the entire surface will be perfectly smooth.
Large Cracks
Large render cracks can be concerning. If these cracks go through the wall and also appear in the brick-and-mortar wall you are likely dealing with a structural issue. Cracks that only reach through the rendering while leaving the brick wall intact can be caused by moisture issues, impact, or material decay.
These types of render issues are repaired by filling out the deep and wide cracks with some render repair mixture. The gaps are usually over-filled a little bit and need to be sanded down once dried. Overfilling and sanding down the excess will provide a smooth and silky finish that can easily be concealed with a coat of paint.
Discoloration on Render
Stains or discoloured patches on the rendering tend to be the easiest to restore. In most cases, the wall can simply be washed and treated with a fresh coat of paint.
However, if the discolouration is caused by water damage, you could have a more severe issue on hand.
If there is moisture trapped within the wall, mould can start to grow on the surface. This type of scenario won’t just cause discolouration on the render surface, the moisture can also damage the wall.
If the wall has moisture inside it then you will first need to identify the root cause of the issue. Most moisture-related rendering issues can occur when there is a leak inside the wall. This will first need to be restored after which the wall will need to be filled out again before sealing it with a layer of paint.
