Surface Materials - Render

 

Render Cleaning

Render usually becomes discoloured by environmental and organic pollutants. Care must be taken when cleaning to ensure the surface is not broken or compromised. Pressurised steam cleans render gently; using steam at 150°C also kills surface-based spores, helping prohibit regrowth.

Where is Render used

Render is often applied to external walls to achieve a smooth or textured finish. Traditional render is cement based and can be tinted or painted after application. Cement render can also be modified to incorporate acrylic – a mixture of plastic polymers and petroleum, to create a more water resistant and resilient surface.

The primary cause of the discoloration of render are biofilms such as moss, algae and lichens. Many factors influence the growth of biofilms including, the building’s orientation in relation to the sun, the pH of the surface, moisture levels and temperature.

Cleaning Render - the method

We usually follow a three-step cleaning process for render cleaning. We start by cleaning the surface using pressurised steam at 150°C, with pressures as low as 40 Bar. This delivers an impressive yet gentle clean and ensures that all the surface based dirt and algae deposits have been effectively removed.

We then treat the surface with a special render wash which kills any biofilms that have become ingrained into the render. The wash also contains a fungicide which helps ensure eradication of spores. A final clean, leaves the surface looking as good as new.

Steam cleaning render uses less water than pressure washing and moisture is not driven deep into the render so the surface can dry more quickly. If water penetrates render it can become trapped. It can then freeze and expand during the winter months causing cracking or blowing resulting in costly repair work.

Steam cleans gently and does not cause the scarring and damage that is frequently associated with traditional jet washing methods. Also, using steam at 150°C kills surface-based spores, helping prohibit regrowth.
