Anti Graffiti Coating Types Anti Graffiti Coatings is a sort of coating that is on top of existing paint or on the facades of the building. These coatings prevent graffiti anti graffiti paint stuck on the wall surfaces. This saves a lot of money for building owners that graffiti removal costs thousands of dollars each year. While there are plenty of programs to fight against graffiti all over the world, vandalism is something that continues to be big problem. World over different companies trying to develop a solution for developing anti graffiti coating that keeps the buildings vandalized by graffiti. These coatings are in the form of a paint is applied on top of existing paint on the walls of the building.
There are different types of anti graffiti coatings that are available on the market, based on the amount of graffiti on buildings or severity of each type have various advantages and disadvantages as well. The types of anti graffiti coatings:
Coatings sacrificial
This kind of anti graffiti coatings are a type of barrier on the wall or surface on which it is applied, protecting it from being vandalized by graffiti. In this case, if the walls or surfaces are affected by graffiti, these sacrificial coatings, as its name suggests, are removed using a pressure washer. When the sacrificial coating is removed, it takes the graffiti with it. Once it is removed from the coating must be applied to walls or surface. sacrificial anti graffiti coatings are generally inexpensive because they use clear polymer materials such as wax, acrylates and Biopolymers. These types of polymers form weak bonds that facilitates easy removal.
Semi sacrificial coatings:
Semi sacrificial coatings are quite similar to sacrificial coatings, they act A as a shield for walls or surfaces on which they are applied after which the pores of the surface is well protected. When the surface gets vandalized by graffiti anti graffiti coatings these can be removed using a combination of solvent that will remove graffiti and a high pressure washer. The major difference in semi sacrificial coating of sacrificial coatings is the fact that the coating should be reapplied every alternate graffiti attacks all attacks instead. The reason for the solvent used with the pressure washer is to prevent erosion of the surface may be possible except that the washer is used.
Permanent Coatings:
permanent anti graffiti coatings are the most costly type of coatings, but having said that, if implemented in right away that they are required to be applied only once. These coatings create a sort of permanent protective surface that ensures that the spray paint can not bind to it. Once the surface is vandalized by graffiti, you will need a solvent that is a very simple and some on the job. The walls or the floor of the building and anti graffiti coating will not be damaged.
