Okon Graffiti Barrier Coat (GBC) is a water base, clear, low VOC coating that prevents aerosol paint and markers from penetrating and permanently staining a variety of architectural surfaces – concrete, brick, plaster, metal, painted surfaces. When used in combination with Okon Graffiti Remover, spray paint and markers can be removed quickly and completely from surfaces protected with GBC. Makes graffiti easy to remove. Goes on clear.

GBC is single-component, non-yellowing, acrylic micro-emulsion. It is a user friendly option to more expensive and dangerous two-component products. It appears milky-white when first applied but dries waterclear to a satin finish, depending on the texture of the substrate and number of coats applied.

A minimum of two-coats on non-porous and three-coats on porous substrates is recommended. The spread-rate of Okon Graffiti Barrier Coat will vary with the porosity and texture of the surface. Always apply material to test area to establish compatibility and spread rate.


Okon Graffiti Barrier Coat is a low-viscosity, ready-to-use product. It can be applied by brush, roller or garden-type sprayer but is best applied using HVLP or airless spray. Apply multiple thin coats at the recommended application rate to avoid runs. When rolling use a highquality, lint-free 3/8" nap cover (Purdy White Dove, Wooster Pro Classic or similar).

Spray Application:

When airless spraying, use a small tip (.011") at the lowest pressure possible to maintain an acceptable spray pattern. When using HVLP use settings intended for fine finish lacquers or varnishes. Apply a light tack coat and allow to flash off before applying a thin wet-coat using a cross hatch pattern. Immediately back brush or roll drips and runs. In hot weather, where possible, lightly spray surface with water to cool the surface to prevent flash drying. Do not stop or interrupt the application in the middle of the wall. Stop application only at expansion joints, walls or breaks defined with masking tape. Do not allow puddles, drips or runs to dry on the surface. Protect adjacent areas for overspray, drips or runs.


Clean hands and tools with soapy water.


While Okon Graffiti Barrier Coat is more durable than common sacrificial graffiti coatings, some cleaning methods may make it necessary to reapply GBC to prevent future staining. GBC may help prevent water penetration due to wind driven rain but by itself is not intended to be used for damp proofing or waterproofing. Okon Graffiti Barrier Coat (GBC) does not prevent graffiti from penetrating cracks or unsealed joints, or prevent damage caused by hydrostatic water pressure or efflorescence. A mock-up should always be performed and approved by property owner.
