Professional® Water Sealant & Anti-Graffitiant is a “Dual Purpose” silicone rubber water repellent which provides invisible protection from graffiti as well as water intrusion.
As an inorganic water repellent, it is easily applied and bonds naturally to a wide variety of porous building surfaces, adding years of weather-proofing protection to new or existing structures.
By applying the Anti-Graffitant prior to vandalism, it establishes a long-lasting, non-sacrificial barrier which prevents paint penetration. This allows for the repeated cycles of graffiti removal when Professional Phase II Cleaner is used.
Graffiti Protection requires a two-coat application
PWS-15 Super
Used as the first coat for all vertical surfaces. Used as the second coat for split face, fluted, expanded shale and most other concrete block.
PWS-8 Extra
Used as the second coat for brick and concrete, stucco, sandstone and limestone.
The following photos show the step by step process of testing Professional Water Sealant & Anti-Graffitiant on a mock up area:
Tape off two 2′ X 2′ areas. On left graffiti protection. On right water repellent protection
On left: First coat PWS-15, then when dry to the touch, second coat of PWS-8 applied. Allow 10 days of cure time before tagging. PWS-8 will be applied in one coat to the right side, to test for aesthetics and water repellent performance.
After 10 days, graffiti applied and RILEM II.4 performed on right panel testing for water repellent protection
Graffiti paint allowed to cure for two days
Spray Phase II Cleaner and let dwell for 5-10 minutes. Use a soft bristle brush if necessary to get paint out of bug holes or mortar. Brush may not be necessary.
Rinse with water from a garden hose or a pressure washer (no more than 1500 psi)
