Do you have unsightly biofilm on your rendering, walls or other exterior surfaces?
Biofilm presents its self on exterior surfaces sometimes visible as black, red, green or yellow marks.
You also may have black spots and lichen that can also be treated using the same methods.
1st Treatment
When treating rendering and other fragile surfaces it is important to treat using chemicals rather than any physical cleaning to avoid damage.
The first treatment used is a hypochlorite mixture that quickly breaks down the biofilms and leaves you with a clean finish.
2nd Treatment
After the hypochlorite das been left to dwell and then rinsed off, A biocide mix is then applied.
The biocide works into the surface and continues to clean the area of applications as well as preventing the biofilm from spawning up to a year guaranteed.
Future growths
If any marks begin to appear in the future it is important to get them treated right away as you will only need touching up with the second treatment to avoid a more costly job!
