So you have seen some black, red or green stains appearing on your render? Should you paint it over it? The answer is definitely no. This is a biological growth that needs treatment and killing before any other options. At DSgo we can offer a Long term treatment that kills and removes the growth allowing the surface to be clean again. If you paint over this, it will only reappear in time, so let us provide a free sample test to show you what our products can do.
