Use this 3-part specification template to specify graffiti-resistant coatings, often called anti-graffiti coatings, for wall surfaces.
What are Graffiti-resistant coatings?
These are specialized coatings applied to the exterior surfaces of buildings to protect them from graffiti. These coatings are designed to make graffiti hard to adhere to the surface, making it easy to remove without causing damage to the underlying surface. They are important for building owners because they can help to protect the building from vandalism and maintain its appearance. Additionally, graffiti-resistant coatings can save building owners money by reducing the need for frequent cleaning and repainting.
Types of graffiti-resistant coating:
- Sacrificial coatings are applied to the surface and are designed to be easily removed when graffiti is applied. They typically form a thin layer on the surface and are made of materials such as wax or silicone. When graffiti is applied, the coating is removed along with the graffiti, leaving the underlying surface undamaged. This type of coating must be reapplied regularly, usually once or twice a year, depending on the level of exposure to graffiti.
- Non-sacrificial coatings, also known as barrier coatings, form a barrier on the surface that prevents graffiti from adhering to the surface. They are typically made of polyurethane or epoxy and are applied in thick layers. These coatings do not need to be reapplied as frequently as sacrificial coatings and can last for several years. However, if graffiti is applied to the surface, it may require specialized cleaning products and techniques to remove it without causing damage to the underlying surface.
In summary, Sacrificial coatings are designed to be removed along with the graffiti, while non-sacrificial coatings forms a barrier on the surface that prevents graffiti from adhering to the surface.
