3 ways to clean render

Cleaning render is an important part of maintaining the aesthetic and condition of your building. The exterior of your building is always exposed to the elements, this can lead to dirt, grime and algae build-up on the render. Not only does this make your building look unsightly, but it can also lead to long-term damage if not cleaned on a regular basis.

Here are a few ways you can deal with the cleaning of your render:

Jet washing

Jet washing is a popular option as it is quick and effective. However, it’s important to be careful when using a jet washer as the high-pressure water can damage the render if it is not done correctly.

Before using a jet washer you need to consider the type of render you have. For example, if your render is finished with pebble-dash then you need to be careful not to blast the pebbles off.

Types of render safe for jet washing include:

  • Sand and cement render
  • Silicone render
  • Acrylic render

If jet washing isn’t suitable then cleaning by hand is another option. This is a slower process but it does mean that you can be more precise and avoid damaging the render.

Cleaning by hand

For smaller areas, you can clean the render by hand using a soft brush and some soapy water. This is a good option for cleaning areas that are dirty but not affected by too much staining. You may also opt to treat the area with a fungicide or biocide after the cleaning which will prevent future growth of algae.

It is recommended that you apply a fungicide once every year, especially in areas prone to fungi growth.

Doff cleaning

Another option for cleaning render is doff cleaning. This method uses a low-pressure, high-volume water jet to clean the render. It is a gentle but effective cleaning method that does not damage the render like jet washing can.

Whichever cleaning method you choose, it is important to be careful and take your time to avoid damaging the render. The best way to prevent damage is to use a professional render cleaning company who will have the experience and knowledge to clean your render safely and effectively.
