Sacrificial Coating - Everything you need to know!
Sacrificial Coatings have an acrylic base.
The graffiti removal process with sacrificial coatings involves using heated high pressure water to remove the graffiti and the coating.
After graffiti removal, the coating must be patch repaired and applied again.
Sacrificial Coatings are best for parts of a building not likely to get targeted by graffiti vandalism regularly.
Sacrificial coatings are especially suitable for sandstone, wood, and heritage listed buildings, but not suited to any surface where the heated high pressure water will damage it, like painted walls.
