What are Graffiti Sealers?

Anti-graffiti sealer prevents graffiti paint from adhering to surfaces. To protect your building from graffiti vandalism, it is applied on top. Protective coatings protect against spray paint, markers, and other products that are used for graffiti and tagging.

Anti-graffiti paints work by preventing inks, aerosols and other markings from adhering to the surface. These anti-graffiti paints are sometimes called anti-vandal sprays. They can be used both internally and externally on many surfaces including bare and smooth surfaces, metal and plastic surfaces, and porous surfaces such as brick and stonework.

Graffiti sealers can be used to protect parks, schools and garages from vandalism. Spray graffiti vandals are protected by a protective film that is applied to any surface. Protective films can be applied to any surface. This will prevent permanent damage and save you time in the event of an attack.

Anti-Graffiti blocks the pores of the surface by applying a thin, clear coating. This prevents graffiti adhering to the substrate and penetrating it. It makes removal simple and complete, without leaving any graffiti shadow. This protects the substrate from graffiti and allows it to be removed with minimal damage. Some substrates are more porous than others and may absorb more product. This is why a third coat, such as sandstone, is necessary. Safety Shield can either be applied with a brush or sprayed.

Vandalism is prevented by Graffiti Sealers

Anti-graffiti coatings may be invisible to the naked eyes. These coatings are made up of solvents which keep the mixture moist throughout the application. However, once the wall has been coated, they evaporate leaving behind the bond. Paints will not stick to walls or faces once they have dried due to their nature.

There are three types of anti-graffiti sealers.

Sacrificial Coatings

A sacrificial coat is a method of controlling corrosion by using thin metal layers with lower electrode potential values and/or higher electrochemical series levels. It creates a protective barrier or coat on the protected surface.

Clear coats that are sacrificially anti-graffiti serve as a barrier to the wall or other surface being protected. The coating can be “sacrificed” if the surface is damaged or vandalized using a high pressure washer. The coating will remove graffiti. Reapply the coating again. The materials used for sacrificial coatings include inexpensive, transparent polymers (such acrylates and biopolymers) that are often low-cost. These polymers can be easily removed because they form weak bonds to the substrate. These polymers are often used to protect against corrosion or other types of environmental damage.

Semi Sacrificial Coatings

Protective coatings are applied to the surfaces using a penetrating sealer (permanent protective component). This prevents paints and varnishes leaking into the substrate. The temporary (sacrificial layer) is then applied, and the graffiti is removed. It is necessary to apply a new coat. You can clean semi-permanent protective surfaces using hot water and high pressure. Chemical graffiti removal is not usually necessary. Semi-permanent paint is best for natural stone walls. It is also used frequently for historic listed buildings.

This coating works in the same way as the sacrificial one: it protects the paint but is easily removed when it is cleaned. After removing graffiti, this coating must be reapplied.

Permanent coatings

Epoxies and polyurethanes are the most common permanent or “non-sacrificial”, coatings. They can withstand cleaning solvents. The cleaner can break down paint dyes but not enough to damage the permanent coating. Permanent coatings can be more costly to install, but they are easier to maintain. An in-house janitor will be able to clean up the permanent coating. It is necessary to scrub the sacrificial coats with hot water pressure washing. This is beyond the scope of regular maintenance.

Although permanent anti-graffiti coatings can be more costly than sacrificial ones, they are only required to be applied once. They are often more cost-effective than sacrificial coatings in terms of maintenance, upkeep, and reapplication. The permanent anti-graffiti coatings create a protective layer that paints cannot adhere to. After the surface has been vandalized, solvents or manufacturer-supplied cleaners are used to remove the graffiti. Cleaning up graffiti is usually as simple as regular maintenance.

Last Thoughts

Graffiti can be beautiful, but it can still attract street criminals. It isn’t an easy task to remove graffiti. You can remove graffiti in different ways depending on how it is placed. Because every substrate reacts differently with paint, this is why you might need to use different methods. Repainting graffiti is the easiest. It is also the easiest to do to the substrate.
