This is a major cause of coating delaminating in moist, damp and poorly ventilated areas.
It can appear as green, black or brown/red.
The only way to remove it is to ensure that the fungal spores (roots) are killed.
- Dilute fungal wash as stated on the container and liberally apply solution to the affected areas, allow to soak for +/- 15-30 minutes and scrub with a nylon scrubbing brush.
- Repeat this process another two times to ensure all fungal spores are killed.
- Rinse thoroughly with clean water.
- Neutralize the affected area with a GP Liquid cleaner and water 1:10 solution and rinse off with clean water.
Note – It is important that both the fungal wash and the GP Liquid cleaner are rinsed off thoroughly
