3 Reasons to Use an Acrylic Render on Exterior Walls

Posted on: 26 August 2020

If the outside of your building's walls need sprucing up, then you may have decided to have them coated with a render. This gives your walls a long-lasting new finish that both protects them and makes them look better.

While concrete renders are popular, there are advantages to looking at other products. For example, an acrylic render has some benefits that you shouldn't ignore. What are they?

1. Get a Ready-Mixed Solution

If you use a cement render, then you mix the material on site. In the right hands, this is a simple job, and an experienced tradie should know how to put together the right proportions of cement, lime and sand.

However, it is easy to get this mix wrong. Even a slight imbalance in the mix can affect how well the render goes on the walls and how well it lasts in the future.

Acrylic renders come ready-mixed. As well as ensuring that you get the right surface for your wall, this also speeds up the application process.

2. Get More Surface Options

A cement render works well on certain surfaces. It is generally a good option for rough substrates like cement, brick and stone, for example. However, this kind of render doesn't work as well on smoother surfaces. So, it may not be the right coating for all parts of your external walls.

Acrylic renders work effectively on more surfaces. Like cement-based products, they do fine on cement, brick and stone. However, you can also apply them to painted substrates, fibre cement and some cladding materials. This might be a better option if any of your walls or your building's exterior doesn't suit a cement mix.

3. Get Flexible Protection

A cement render sets hard. It creates a protective shell on a wall. However, cement's strength can also be a problem.

This material doesn't have any flexibility. So, if external conditions or weather affect the cement, it is more likely to crack or split. Once this happens, it loses some of its closed structure and stops protecting the walls under it.

An acrylic render has some flex in it. Its acrylic content can expand and contract more without cracking. This kind of render should last for longer without needing repair work or replacement.
