- Spray or brush application
- Surface Preparation and Application
- Prior to application all surfaces shall be structurally sound, clean, and dry, free from oils, dirt, debris, or minerals such as efflorescence, lime, and calcium.
- To ensure the surface is as clean as possible, wash with soap and water, rinse thoroughly, then allow to dry completely. This is especially important when applying over painted, stained, or wood surfaces. Mix thoroughly before application.
- Avoid aggressive agitation that may produce excessive air generation or foaming. Apply using a low-pressure airless spray equipment at a rate of approximately 250 sq ft per gallon. If using a brush, use enough material to create a sufficient film build to achieve a wet film thickness of 5 - 6 mils. When spraying, apply in a cross hatched pattern to ensure complete coverage of the surface.
- Clean equipment with soap and water when finished.
- Application Temperature: 40°F - 100°F
- Relative Humidity: 90% maximum
- Graffiti resistance is fully developed after a cure time of 7-14 days.
- Graffiti Removal
Remove graffiti with a power washer (1300-2175 psi) and cold water. For difficult removal, use warm to hot water while power washing.
For delicate surfaces, use a soft bristle brush, soap, and water. Gently scrub the area until the tagging is removed. Rinse the surface with water afterwards.
For more difficult graffiti, a commercially available graffiti cleaner may be required.Property Value Unit of measure Test Method Graffiti removal Cleanability 1 Graffiti completely removed with high-pressure cold-water wash ASTM D7089 Graffiti removal Cleanable with dry rag Permanent marker ASTM D6578 Graffiti removal Cleanable with Isopropyl alcohol Acrylic spray paint ASTM D6578 Graffiti removal Cleanable with Isopropyl alcohol Alkyd spray paint ASTM D6578 Graffiti removal Cleanable with dry rag Wax crayon ASTM D6578 Graffiti removal Cleanable with detergent Ballpoint pen ASTM D6578 Graffiti removal Cleanable with dry rag Water-based marker ASTM D6578 - Precautions
Use material in a well-ventilated area. Protect all other areas not to be coated from overspray.
PerformaSilTM 200 Anti-Graffiti Coating should not be applied:- When there is a threat of rain within the next 48 hours, or the relative humidity is in excess of 90% (such conditions would not permit complete drying)
- In temperatures below 40°F or above 100°F
- On asphaltic materials, or on tar-contaminated masonry
- On newly applied or green cementitious materials - industry guidelines recommend at least 28 days cure before painting or coating such substrates
