Can moss and algae killer be used before painting the surface?
If you wish to remove moss and algae on surfaces such as walls before coating, then you can apply Baticlean CR
. It is a systemic surface biocide and will not affect the paint.
Dilute Baticlean CR
in water as per the label instructions, spray on the surface and leave to act without rinsing. It will take a few days and then you can, optionally, clean down the surface with a brush and/or rinse. You can then apply another treatment of Baticlean CR
if you wish to leave protection under the paint.
