For modern buildings acrylic rendering is a popular choice, as it is a cost-effective and versatile solution for providing a smooth, best finish to exterior walls. Acrylic rendering combines cement, sand, and acrylic polymers to create a protective coating on the wall surface. Also, like any construction material, acrylic rendering can go wrong, leading to a range of issues that can affect the quality and durability of the render.

In this article, we will explore what can go wrong in acrylic rendering and how to avoid these problems.

Improper mixing

Acrylic rendering is a precise mix of cement, sand, and acrylic polymers. Cement, sand, and acrylic polymers are blended to create an acrylic render. The render may dry out too rapidly if the mix is off, leaving a soft, fragile finish prone to cracking. To create a uniform, usable mix, following the manufacturer instructions and utilizing the right amount of water and mixing time is crucial.

Or it is better to hand it over to the professionals of JR rendering to get the best result. The final quality can be impacted by the mix being too thick or thin, so it should be constantly examined to be sure.

Insufficient Curing Time

Letting the render dry completely is a further common mistake. Acrylic rendering and cement rendering need time to dry and firm; if the render is not given enough time to cure, the finish may be fragile, brittle, and prone to cracking. The drying time will vary according to the surrounding area temperature and humidity. Still, generally speaking, the render needs to cure for at least seven days before painting or decorating.

Insufficient Surface Preparation

Poor surface preparation is one of the most common reasons for acrylic rendering problems. The wall surface must be dry, clean, and free of loose or flaking material before the render is applied.

Inadequate surface preparation can cause adhesion issues, which can cause the render to flake or peel off the wall. With a pressure washer or scraper, removing any dirt, debris, or loose material from the surface is imperative. Before applying the render, any cracks or holes in the wall should be sealed with the proper filler and given time to dry.

Poor Surface Preparation

Poor surface preparation is one of the most frequent reasons for acrylic rendering problems. The wall surface must be dry, clean, and free of loose or flaking material before the render is applied.

If the surface is not properly prepared it will cause may problems? It is very important to clean the surface before anything started. Any gaps or cracks in the wall should be filled with the right filler and allowed time to dry before the render is applied.

Using bad-quality materials you can get problems with acrylic rendering and texture rendering

Acrylic render should be applied uniformly. If the render is too thin, it may not provide enough protection, and the wall may be susceptible to damage from weather, moisture, and other factors.

Conversely, if the render is too thick, it may crack or shrink as it dries, resulting in a better- quality finish.
