Application of Anti-Graffiti Coating:
Coverage: Apply materials at rate per square foot recommended by the material manufacturer.
Application Sequence: Apply two coats of the material "Graffitibase" followed by one coat of "Graffiticatcher" in compliance with manufacturer's specifications and recommendations.
A minimum drying time of two hours should be allowed between the first and second coats of "Graffitibase".
A minimum drying time of 4 hours should be allowed between the "Graffitibase" and the "Graffiticatcher".
Anti-graffiti coating process should achieve a non-yellowing, durable, clear film completely protecting the substrate from penetration of paint, ink, crayons, dirt, air pollutants, grime and similar materials and help maintain and protect the original appearance of the surface.
"Graffitibase" material should be applied with a "crosshatch" method of several horizontal passes followed immediately by vertical passes to build up a heavy wet film to insure sufficient uniformity. This is considered one coat and the same method is repeated for the second coat to build a minimum dry film thickness of 3 mils. Spray large areas in sections so overlap occurs before previously coated areas have dried. Start application at top of wall and work down surface. Schedule work so that the stopping point each day falls at an opening, column or corner.
"Graffiticatcher" should be applied with a "crosshatch" method of several horizontal passes followed immediately by vertical passes to build up a film to insure sufficient uniformity. This is considered one coat.
