Mapei WallGard Graffiti Barrier is recommended for protecting marble, granite or natural stone facings against graffiti drawn with spray-paint, crayons, markers, etc.

Best Uses

Mapei WallGard Barrier is a reversible graffiti-resistant protective barrier for all surfaces. WallGard Graffiti Barrier is also recommended for protecting cement-based facings. WallGard Graffiti Barrier does not alter the appearance of the surface. WallGard Graffiti Barrier forms a film that covers surface pores without affecting vapour permeability, creating a repellent barrier against oils and water that prevents graffiti from penetrating deeply.

Ideal for all surfaces that are potential targets for graffiti, such as:

• All types of natural stone facings
• Brick or concrete block facings
• Concrete facings
• Renders resistant to high pressure cleaning with hot water
• Pre-painted wood and iron structures.

Also available from Promain is Mapei WallGard Graffiti Remover Gel, recommended for all surfaces not previously treated with graffiti-repellent protection against conventional spray-paints.

Application

Preparing the substrate
The surface to be treated with WallGard Graffiti Barrier must be perfectly clean and solid. Completely remove dirt, dust, grease, oil, and saline efflorescence by sanding, sandblasting or high-pressure cleaning. Wait some hours before applying WallGard Graffiti Barrier, which can be applied even when the substrate is slightly damp.

Preparing the product
WallGard Graffiti Barrier is ready to use and should not be diluted with water or solvents.

Application procedure
WallGard Graffiti Barrier can be applied with brush, roller, spray or airless gun. The latter are preferable for rough or irregular surfaces. For thorough impregnation WallGard Graffiti Barrier should be applied to saturation in a single coat. On very porous surfaces, apply a second coat, if needed, 20 minutes later at +20°C.

Graffiti removal
Graffiti can be removed from surfaces treated with WallGard Graffiti Barrier using hot water (about +80°C) in a high pressure cleaner. Traces of graffiti that have penetrated into the surface may be removed with Mapei WallGard Graffiti Remover Gel,, a special detergent gel. (see Technical Data Sheet). After removing the graffiti with high-pressure cleaning, renew the protection with a new application of WallGard Graffiti Barrier even if the surface is slightly damp.
