Rust stains on your render can be unsightly and may even reduce the value of your property. But with the right cleaning methods, you can make rust stains a thing of the past. Before we explain how we remove rust stains from commercial exteriors let’s delve into what causes this unsightly mess.

What is Rust?

Rust is a type of stain that can be difficult to remove from surfaces and is recognisable by its ready brown hue. It’s caused by the corrosion of iron-containing compounds, and usually takes years to form. Stains can appear when an iron-containing metal is regularly exposed to oxygen and water.

What causes rust stains on render?

One common cause of rust stains on commercial exteriors is metal ventilation grates. When these grates rust, the reddish flakes of oxidation appear on the render below. This is the same for any metal underneath the surface of the render, such as iron bars. If the metal is exposed to damp or wet conditions, it will gradually start to corrode and rust.

Other causes of rust on render can include;

Damp – If there is a lot of moisture in the air, this can cause condensation, which is likely to lead to staining.

Pollution – Areas that are prone to high levels of pollution, such as near a busy road, are more likely to develop rust stains, harmful chemicals in the air can speed up the corrosion process.

Wet conditions – If the render is constantly exposed to damp or wet conditions, this can also cause rust to form.

What are the effects of rust stains on render?

Rust stains on render will generally not cause any major complications to a property’s structural integrity. This doesn’t mean there is no impact at all, rust stains are ugly and can give your building an old, damaged appearance.

If you have clients visiting this doesn’t give a very good impression of your company and may even lose you business.
