Protecting Buildings and Monuments from Graffiti

While some may feel graffiti is a form of artistic expression, others view it as a nuisance and an eyesore costing businesses and industries billions of dollars every year worldwide. The application of this type of vandalism can take mere seconds while the clean up can take days. Graffiti has become a widespread problem to both personal and business property as well as historical monuments. Manufacturers have been working hard to come up with various paints and coatings that can help to alleviate this problem and provide protection from taggers.

Businesses and homes have had to deal with vandalism for years. Taggers cruise the streets nightly looking for another place to leave their mark. It can be quite frustrating and disheartening for home and business owners to have to deal with this type of destruction each and every day. Paint manufacturers have worked tirelessly to come up with an anti-graffiti paint to help solve this problem. They came up with two types of paint that can be used in this situation. Sacrificial coatings are a paint type that is applied and then easily removed along with the graffiti. Whereas permanent coatings actually have a chemical make-up that creates a protective surface and prevents graffiti from adhering. New anti-graffiti coatings have charged polymeric materials which form a gel on the surface, adhere without damage to the substrates, are water repellent, environmentally friendly, UV resistant, and can be efficiently cleaned.

One of the biggest issues when it comes to graffiti is the impact it has on historical monuments and buildings. While commercial buildings and walls can usually be painted over or scrubbed down when they are defaced by vandals, a historical landmark cannot. Using caustic solutions to remove paint from these can be extremely harmful to its underlying surface. Anti-graffiti polymer coatings were created which provides a hydrophobic seal. This closes off the pores and prevents the paint from adhering to the inner surface. While this may sound like a good idea in theory, it actually has some problems. Completely closing off all pores can inhibit air flow which could lead to problems such as mold. A scientific research group headed by Professor Andre Laschewsky came up with a solution to this problem by creating a polymer coating that seals the pores in the substrate while its micro-porous structure creates a barrier which enables the pores to breathe properly. The coating can also be removed easily when needed using a diluted brine solution.

Through the innovation and determination of researchers and manufacturers it is now possible for homeowners and businesses to easily protect their investment from graffiti and tagging vandalism. Not only this but the integrity of historical landmarks, monuments, and buildings can be maintained and upheld to last through the test of time. Through the use and application of sacrificial, semi-sacrificial, permanent, and polymer coatings graffiti defacing is no longer the burden that it once was. These coatings can provide important and valuable surfaces with all year protection against graffiti and taggers.
