This is an image of a render that we cleaned in Ormskirk Lancashire. However our job yesterday was in Preston. Rendered surfaces can become infected with green or red algae and the temptation is to paint over it. Do not do that until the infection has been killed and treated. This should be done gently and thoroughly. Very often this is all that is needed and painting becomes unnecessary as the colour returns to its original form.
A good professional use biocide will do the trick and luckily enough we provide the service required!
Should I paint my render? How do I treat algae in my render? Why is my render green? Why is my render red?
