What render type do you use?

Before you start cleaning your exterior render, you must first know what kind it is. There are many modern renders available, some of which can be mixed with polymers to provide protection.

Others renders may require different tools and treatments. Some are resistant to jet washing, but others are not strong enough to withstand water. If you’re unsure about the type of surface that you have, contact the manufacturer for more information or to arrange for a cleaning service to examine it.

Next, determine the kind of dirt, grime, or stains that your rendered wall has. Many things can affect the exterior wall of a house, including dirt, mould and algae.

You can identify the type of issue that is related to your render so you can address it appropriately.
Jet/Pressure Washing

Many modern render manufacturers recommend that you use a jet or power washer to remove any algae growth. Pressure washing can clear render surfaces of discolouration due to metalwork, weathering, or algae. Power washing can restore the building’s glory as long the stain has not become deeply embedded.

Pressure/jet washing isn’t suitable for all render types. Modern renders may be more durable than older ones. They can be easily damaged or eroded with the water jet.

Ask the manufacturer or a render maintenance professional if you are unsure if your building can be cleaned.
Detergents

You will need detergent to achieve the best results when cleaning render. The detergent is used to clean the render surface of algae and other blemishes. It makes it look brand new.

Most cases, small discolourations can be easily removed using a sponge and detergent. For stubborn stains, detergent and a gentle spray wash will be required.

A render cleaning Cardiff service will provide you with the best render care, so that your investment doesn’t go to waste.
Fungicide

Fungus growth is often responsible for discolouration and staining. Buildings that are exposed to the elements often have fungi. It is often found near windows, balconies, or under rooflines.

The fungi can not only discolour the property’s exterior but also cause render damage if they aren’t cleaned up. If not cleaned, it can cause further damage and even require re-rendering.

Regular fungicide application will not just remove existing growth, but it will also prevent future growth. This is particularly true when the fungicide application is made after the property has been power washed.
Biocide

The exterior of a building can also lead to algae growth, much like fungi. Algae growth on exposed surfaces can be just as destructive as fungi and can result in serious render damage.

The application of biocide after and during cleaning will reduce potential regrowth and remove any algae. It is important to apply biocide at least once a year to your property. This will help prevent algae growth.
Re-Rendering

If a patch of render becomes discoloured or severely damaged, it is possible to re-render it. Render manufacturers recommend that damaged render be removed and rere-rendered.

However, it is unlikely that the property will have the same appearance as the others. A re-render should not be performed to an entire panel, or in situations where cleaning is not possible.
Custom Solutions

Some companies even have their own process of cleaning render. They employ their own cleaning methods and solutions to remove dirt, stains and organisms from render surfaces.

This is the best method to clean exterior renders. Each surface has different needs. Exterior renders are no different from people. Each person has their own set needs.

There is no one-size-fits all solution for render cleaning. The best approach to the problem is to create a plan that addresses each render individually. One solution might work for one property but not another.

If you want to achieve the best results possible, it is important that you use professional and customizable render cleaning solutions.
