There are extensive drawbacks associated with vandalism through graffiti paint on commercial and residential buildings. The markings created on the walls will destroy the aesthetic value of the structure and cause a significant decline in the property value. There are also high costs in terms of the cleaning material and labour linked to frequent graffiti removal. In addition, the frequent manipulation of the surfaces can weaken the walls. If you own or lease a building which is constantly targeted by vandals, you should consider purchasing and applying anti-graffiti products.
These are coatings which are designed to prevent the graffiti paint from bonding to the wall surfaces. Ideally, a good anti-graffiti product should be water-repellent and have good cleaning efficiency. The coating should also adhere to the wall effectively without causing damage to the wall. Companies like Allcool Window Tinting offer graffiti coatings specifically for windows.
Moreover, ensure that your chosen product displays have no toxic components and are treated against UV degradation before purchase. Here are the main types of anti-graffiti coatings available in the market.
Sacrificial anti-graffiti coatings are designed for easy removal after destructive vandalism. Basically, the product is a clear protective coating which is applied on the target surface or wall. The material is made from polymers like waxes, biopolymers and acrylates which form a relatively weak bond to the substrate. This means that the coat can be removed along with the graffiti paint using cleaning methods such as high pressure washers. In simple terms, the anti-graffiti coating is sacrificed and reapplied after washing.
The semi-sacrificial coating is a protective layer which is somewhat similar to a penetrating sealer. The material is designed to act as a surface shield by infiltrating the pores on the substrate or wall structure. The coating acts as an anti-graffiti layer because it allows easy cleaning of the damage without eroding the building. Basically, when the surface is vandalised, you will be able to use a solvent for graffiti removal and a high pressure washer to clean it. You will not need to reapply the product after every wash. You should check the manufacturer's recommendation on the frequency of the task. Additionally, do not rely on pressure washing only for graffiti removal because it accelerates damage of the coating.
Permanent coatings are typically more expensive than the sacrificial alternatives. However, their durability and expediency will offset the initial costs. These products are made from compounds such as polyurethanes, siloxanes and nano-particles. The coatings resist bonding with the graffiti paint; therefore, you can eliminate the damage with a solvent.
