Then scrub, sand, waterblast or sandblast the graffiti. Try using detergents and softly scrub. If this is not successful, seek professional advice. Protected surfaces Graffiti protection coatings are painted on top of natural or painted surfaces to form a protective shield. Graffiti will stick to the protective coat instead of the normal surface.
Many different products are available and are usually either clear or sacrificial coats.
Clear coat is a long-life, hardened cover similar to a clear varnish or paint, from which the graffiti can be wiped. Sacrificial coats are totally or partially removed with the graffiti. Before purchasing a graffiti protection coating, we suggest you consider the cost and what product best suits your situation. You may require professional advice. The manufacturers directions should be observed when working with solvents, chemicals or machinery.
