Chemical Render Wash
We use an effective chemical composition designed for use on external surfaces that kills algae, mould and other organic material instantly for our exterior cleans
of render, sandstone, tiles/paths and much more.
We then treat the clean area with biocide which prevents organic growth for up to 5 years. Much longer than pressure, steaming, or painting alone.
It has been tested and proven not to cause concern for health and meets all safety regulations. It will not harm surrounding vegetation in a garden or other sensitive surface because of our preparation and application.
