.DESCRIPTION AND USES .

OKON

Graffiti Barrier Coat (GBC) is a clear, single

component, water-based, non-yellowing, low VOC acrylic

micro-emulsion coating that prevents aerosol paint and

markers from penetrating and permanently staining a

variety of architectural surfaces including concrete, brick,

plaster, metal and painted surfaces. When used in

combination with OKON Graffiti Remover, spray paint and

markers can be removed quickly and completely from

surfaces protected with Graffiti Barrier Coat.

GBC is recommended for use on concrete block, stone,

wood, aggregate panels, EIFS, new paint

, brick, metal,

fiberglass, cast concrete, cement, plaster, stucco and

previously painted surfaces.

Allow paint to completely cure before topcoating with

Graffiti Barrier Coat – 14 days.

.FEATURES .

 Prevents permanent stains caused by spray paints and

markers

 Protects painted and unpainted surfaces

PRODUCT APPLICATION .

SURFACE PREPARATION

OKON Graffiti Barrier Coat can be applied to surfaces that

are clean (free of dirt and oils), dry and sound. Surfaces

can be slightly damp, but must be internally dry.

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 sulfamic 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.

PRODUCT APPLICATION .

SURFACE PREPARATION (cont.)

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.

WARNING! If you scrape, sand, or remove old paint, you

my release lead dust. LEAD IS TOXIC. EXPOSURE TO

LEAD DUST CAN CAUSE SERIOUS ILLNESS SUCH AS

BRAIN DAMAGE, ESPECIALLY IN CHILDREN.

PREGNANT WOMEN SHOULD ALSO AVOID

EXPOSURE. Wear a NIOSH-approved respirator to

control lead exposure. Clean up carefully with a HEPA

vacuum and a wet mop. Before you start, find out how to

protect yourself and your family by contacting the National

Lead Information Hotline at 1-800-424-LEAD or log on to

www.epa.gov/lead.

APPLICATION

Graffiti Barrier Coat is a low viscosity, ready-to-use

product. Stir, do not shake. Apply when air and surface

temperatures are between 50-90°F (10-32°C) and the

relative humidity is below 85%. 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 high quality, lint-free ⅜” nap roller cover. 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.

Spray Application – When using airless spray, use a small

tip (0.011) at the lowest possible pressure 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 it 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 by masking

tape. Do not allow puddles, drips or runs to dry on the

surface. Protect adjacent areas from overspray.

DO NOT APPLY if rain or freezing temperatures are

forecast in 12 hours after application.

COVERAGE LIMITATIONS A minimum of two coats on non-porous and three coats on porous surfaces is recommended. The spread rate of GBC will vary with the porosity and texture of the surface. Always apply material to a test area to establish compatibility and spread rate. Some cleaning methods may make it necessary to reapply GBC to prevent future staining.
