Anti Graffiti Coatings are known for its durability and application ease. It doesn't allow paint, permanent markers, stickers, graffiti or any other markings to bond to the dry film. By re-spraying the surface you can repair the damage coating. Anti-Graffiti Coatings are generally non-stick coating and are UV stable. This coating is water-clear and has great chemical resistance. The frequently used paints are latex and acrylic paint and oil-based paint.
Anti graffiti coatings are perfect for preserving historic buildings as they are invisible to the naked eye. This coating has an excellent cleaning efficiency. Chemical composition of this coating is environmentally-friendly. They are of two types: sacrificial coating and permanent coating. A sacrificial coating helps in protecting the wall or surface. It creates a clear coat barrier over them. Use a high-pressure washer for removing the coating if the surface is damaged. The surface should be clean and dry before applying the new sacrificial coating The surface and air temperatures must be 40-90°F (4-32°C). You should not apply sacrificial coating during rain showers. Polymers like biopolymers, acrylates and waxes are used for making sacrificial coating. These polymers produce weak bonds so that it is easily removed.
Permanent coatings are effective and flexible. They are expensive when compared to sacrificial coatings. They are waterproof and will stretch and shrink with the substrate. It will bond to surfaces like wood, concrete, vinyl cladding, metal, stucco and both asphalt if applied and used appropriately. It is UV resistant and allows moisture to flee from the substrate. Fluorinated hydrocarbons, Polyurethanes, siloxanes, and nano-particles are kinds of permanent coating. Fluorinated hydrocarbons coatings are very durable and chemically inert. Polyurethane coatings resist corrosion and chemical exposure. They are useful because of their barrier properties. Silicon coatings are hydrophobic (water-repels) on surface. It helps in reducing the effects of photo-oxidation of surfaces.
