DURASHIELD AC PRIMER

Durashield AC Primer is a water-based penetrative primer used to seal both interior and exterior weathered asbestos or non-asbestos (Nutec) fibre cement roof sheets by penetrating through existing fungus, lichen and degraded asbestos to a suitable surface and by binding all of these unstable elements.

The primer also has anti-fungal and algae additives to eliminate regrowth of lichen and moss. It forms part of the OPTIMA COATINGS DURASHIELD ASBESTOS
ENCAPSULATION SYSTEM when used in conjunction with Durashield 850 HB for external weather exposed environments.
