A new anti-graffiti system now commercially available has been used to safely remove stubborn graffiti and apply a non sacrificial wateproofing/anti-graffiti coating from the landmark headquarters building of the National Audubon Society on Broadway in New York City.
The graffiti was removed from the Society building's exterior facade, which is classic (and porous) "New York Brownstone" and mixture of brick, sandstone, and terracotta using Wipe Out. The new coating applied to the building was Dumond Anti Graffitiant.
Dumond Anti Graffitiant is a graffiti inhibitor that has all the characteristics of a penetrating weather proofing material and is prepared by using Silicone Rubber which has a high perm rate which allows moisture vapor to escape while preventing liquids or graffiti to enter the substrate.
Dumond Anti Graffitiant has been on the Audubon Building for 5 years without needing recoating, even though the building has been hit by graffiti many times over the years.
