Coval Anti-Graffiti Coat

Coval Anti-Graffiti Coat may be used to apply a non-porous, super hard, chemical resistant coating, to almost any surface as a protection from spray paint, marker pens, and other unwanted products. Once the Anti-Graffiti Coat is dry and hard, it will be unaffected by chemicals, solvents and cleaners. Once protected – graffiti, spray paint etc., will have difficulty bonding with surfaces, due to the super hard surface formed by the nanotechnology, which creates a covalent and ionic bond with the substrate, and itself. Graffiti of all kinds becomes easy to remove; sometimes, with only soap and water. (We recommend using Coval Graffiti Remover).

This is a non-sacrificial protection system. (The coating is unaffected by solvents or cleaners, and is not removed with the graffiti.)

Application

We recommend applying the coating with a HVLP (high-volume-low-pressure) spray system. (1.0 size tip @ 25 to 30 psi.) Prepare surfaces with Coval Step#1 Cleaner as per instructions. Surfaces should be clean, dry and free of dust or wax, prior to application of Anti-Graffiti coat. Mask off all areas not to be painted. For porous surfaces, first apply one coat of Coval Quick Seal & Enhance to build up the surface.

Caution: A professional spray mask should be used with this product; as well as eye protection, rubber gloves and coveralls.

Note: In some cases it may be necessary to apply Anti-Graffiti coat with brushes or rollers; carefully test materials and surface before proceeding, as many surfaces and plastics may temporarily soften when in contact with Anti-Graffiti Coat. Clean up with acetone while the product is still soft.

When applying the coating outdoors, it is important to avoid humidity and rain while the coat is drying. (Allow 5 hours minimum)

Note: As Anti-Graffiti Coat dries almost completely transparent, it can be difficult to detect areas that are not properly covered, even during application. Care should be taken to methodically cover full sections and surfaces.

Maintenance

To remove graffiti, after the Anti-Graffiti Coat has been applied, use Coval Step #3 Graffiti Remover as per instructions, then rinse with fresh water. Avoid using abrasives, which should be unnecessary. For surfaces that are uneven, work the cleaner into cracks and pot marks with a new, soft, hair brush.
