Prevent unwanted graffiti and tagging with anti graffiti paint
Graffiti decreases the value of buildings and may create an unpleasant environment. Qatar’s Ministry of Municipality and Environment (MME) launched a video in 2017 stating: “You mar your country, you mar yourself.” The government wants to discourage Qatar residents from marking up walls and other property without permission. There are also options you can undertake yourself. For example: unwanted graffiti should be removed as soon as it is noticed to prevent other culprits from making it their “Graffiti spot”. but graffiti cleaning is not an easy job, nor is it cheap. Fortunately, anti graffiti paint makes removing graffiti easier and more affordable.
In this article we will provide you with all information about anti graffiti paint for different substrates.
The two main types of anti graffiti coating you can choose from
Anti graffiti coating is purposed to make graffiti or tagging easy to wash off with high pressure, hot water and soap. They form a protective layer on a substrate where graffiti is likely to appear. Thanks to the coating, the graffiti never reaches the substrate but remains on the coating layer instead. Anti graffiti coating comes in two forms which are suitable for almost any substrate. Which form you choose depends upon the likelihood of your property suffering from graffiti vandalism and the amount of money and maintenance you want to invest.
1. Permanent anti graffiti coating
Recommended for: surfaces that are likely to experience graffiti frequently (public buildings, schools, alleyways, bridges and railway walls)
Permanent anti graffiti coatings (non-sacrificial) make use of nanotechnology, which allows the coating to become one with the substrate. These coatings form a water repellent surface where the graffiti spray paint, permanent markers, or ink cannot properly adhere. The permanent anti graffiti paint remains functional for 5 to 8 years and endures some 70 graffiti removals.
2. Sacrificial anti graffiti paint
Recommended for: surfaces at low to middle risk of graffiti (houses, public benches, garage doors and so on)
Sacrificial or temporary anti graffiti paint is usually a silicone wax which washes off together with the graffiti. It forms a protective film to which the graffiti can adhere without reaching the underlying substrate. As the coating is sacrificial, it needs to be reapplied after removing graffiti.
Guidelines for choosing the anti graffiti paint based on the substrate
For graffiti artists, there is no difference between substrates. Therefor graffiti prevention coatings have been developed for multiple materials. There are transparent systems, but you can also opt for colour. Suitability for substrates varies per coating – always check the specific instructions from the manufacturer.
There are waxes and permanent systems for hard and soft wood. If you want the natural appearance of the wood to stay visible, opt for a clear system. However, anti graffiti paint does not prevent natural greying of the wood. When you do not want discoloration to show an opaque system is a better choice.
Surfaces: doors, facades, street furniture, fences and gates
Metal surfaces are most often coated with a permanent opaque or transparent nano coating system. Some waxes are also possible, but often not convenient because they do not adhere that good.
Surfaces: exteriors of trains, tubes and buses as well as metal doors and sidings
- Concrete (masonry, stucco, bricks etc.)
The most common choice of anti graffiti paint for concrete is clear permanent system. However, clear and sacrificial systems are also applicable.
Surfaces: bridges, facades, walls, fences and underground tunnels and stations
Products and services for Anti Graffiti in Qatar
Protecting small surfaces from graffiti is often a DIY-job, but as the surface area gets larger, the application requires more expertise. Here are a few products for applying anti graffiti coating yourself. Keep in mind that you should always follow the manufacturer’s advice when it comes to the compatibility of the substrate and the coating.
