How to apply anti-graffiti paint to a facade? In this article, we take a closer look at the topic of graffiti protection. What is anti-graffiti protection? And how is an anti-graffiti coating applied with an airless spray gun? Using the example of the facade of an ice cream parlour in a popular Berlin beer garden on the banks of the local river, we will show you how easily an anti-graffiti coating can be sprayed on with an airless pump.

 

We have compiled detailed information on the application of graffiti protection with airless pumps in this article under the following points:

  • What is anti-graffiti paint?
  • Anti-graffiti protection on the facade of a glacier
  • Information on the anti-graffiti protection used
  • How is airless anti-graffiti paint applied?

What is anti-graffiti paint?

Coatings that protect surfaces from unwanted graffiti or dirt are called anti-graffiti protection or anti-graffiti paint. The anti-graffiti coating is applied to the surface and protects it. These coatings are mainly used on the outside, for example on the facades of residential, public or commercial buildings. If graffiti is applied, the anti-graffiti coating can be easily removed using a high-pressure cleaner with hot water. The unwanted coating is then also cleaned with the protective layer.

Anti-graffiti protection on the façade of a glacier

This project concerns a small facade that is part of a popular Berlin ice cream shop located directly on the Spree. The facade was visually designed with glacier motifs and then covered with a graffiti protection. In the meantime, graffiti has appeared. In order to remove the unwanted graffiti, the graffiti protection layer was already removed with a high-pressure cleaner and hot water. The facade has dried and now needs to be re-coated with a graffiti protection.

Information on the anti-graffiti protection used

The anti-graffiti coating used provides temporary protection against graffiti as well as volatile elements such as dust or soot. The anti-graffiti protection is especially suitable for application on vertical building surfaces, such as facades. The anti-graffiti paint can be applied to almost all water-resistant porous and non-porous surfaces. The material is not suitable for surfaces pre-treated with water repellents. Protective coating of plastic and metal surfaces is also possible with this material, but requires prior priming if necessary.

The graffiti protection coating used is based on natural polysaccharides and water and is harmless to people, animals or the environment. The material is transparent and no longer visible after application. The appearance of the surface or facade is therefore fully preserved.

How is airless anti-graffiti paint applied?

The manufacturer recommends applying the coating with an airless device. Before applying the anti-graffiti paint, the surface must be clean, dry, free of dust and grease. Porous surfaces must be moistened to prevent the graffiti protection from penetrating deep into the surface structure. The material must be thoroughly mixed before application. It is then sprayed onto the surface in two cross-coats. The manufacturer of the graffiti protection recommends airless nozzles of size 217 or 319.

Which airless pump was used to spray the graffiti protection?

The original plan was to use a Graco Ultra Max II 695 Procontractor to spray graffiti protection. This model is ideally suited for medium to large facade areas. However, since only a small amount had to be sprayed on a few square meters, we finally opted for the Graco GX FF Cordless with battery. The spray was done with a 0.019″ nozzle, which applied enough product.

Why use an airless gun to apply anti-graffiti paint?

The airless spray technique offers some advantages when applying graffiti protection. The protective coating is quite viscous and can be sprayed evenly and over a large area using an airless device. The material is applied in cross strokes, i.e. from top to bottom and then from right to left, so that it is evenly distributed in a sufficiently thick layer. This ensures a durable protection of the entire surface.

In addition, uniform spraying with the airless avoids optical disturbances on the surface due to uneven application of the material. However, the use of an airless spray gun also increases the speed of work, as large surfaces of facades or walls can be treated quickly and time-savingly. Structured surfaces such as plaster, bricks or ornaments can be coated evenly over the entire surface in a single pass by spraying.
