TECHNICAL DATA BULLETIN
DESCRIPTION
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.
Prevents permanent stains caused by spray paints and markers
Protects painted and unpainted surfaces
Interior/Exterior - Waterbase – Low VOC – Non-yellowing
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 water-clear to a satin finish, depending on the texture of the substrate and number of coats
applied.
RECOMMENDED USES:
Concrete block
Brick
Stone
Metal
Wood
Fiberglass
Aggregate panels
Cast concrete
EIFS
Cement plaster & stucco

Allow paint to completely cure before topcoating with GBC –14 days minimum.
Do not apply if rain or freezing temperatures are forecast in 12 hours after application.
SURFACE PREPARATION
OKON Graffiti Barrier Coat can be applied to surfaces that are clean (free of dirt and oils),
dry and sound. (Surface can be slightly damp, but must be internally dry.). Do not apply if ambient air or surface temperatures are below 50º or over 90º
F. Concrete: New concrete must cure for 28 days prior to coating. Where specified, water-repellents and water-proofing membranes should be applied
a minimum of fourteen days prior to applying GBC. Clean exterior surfaces by power washing to remove dust, mildew, form releases or other foreign
matter. The surface of concrete and mortar joints must be hard and firm - not loose or sandy. Remove efflorescence with suflamic or dilute muriatic
acid. Spot cleaning with acid may cause uneven porosity and blotchy appearance. Rinse the surface thoroughly after chemical cleaning. Un-rinsed acid
salts may cause whitish-blotches to appear. Allow washed surfaces to dry three days prior to coating. Painted Surfaces: Paint must cure a minimum
of 14 days prior to coating with GBC. Clean painted surfaces to remove dirt, chalk, mold and algae. Glossy surfaces should be sanded to ensure
adhesion. A test is always recommended.
COVERAGE
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
