Pro Roc Aq


Preventive product for limestone and soft stones. PELICOAT PRO ROC AQ is a mixture that once applied on a friable mineral material hardens its surface as well as weatherproofs it. The treatment crystallizes soft stone surfaces and provides them with a protection against natural degradation caused by water infiltration, freeze and thaw cycles. It reduces moss, lichen and algae growth as well as saltpeter. PRO ROC AQ is an aqueous product which allows the treated material to breathe.
