Anti-Graffiti Coating: What Strata and Facility Managers Should Know Before a Repaint

Graffiti is one of the fastest ways for a well kept building to look neglected, and it rarely turns up just once. If your building has ground level walls, roller doors, fences or car park entries that keep getting tagged, an anti-graffiti coating applied as part of your next repaint can make each clean up quicker and cheaper. This guide explains how anti-graffiti coating works, the main types available, which surfaces to include in the scope and how to plan it so the protection lasts until the next repaint cycle.

How an anti-graffiti coating works

An anti-graffiti coating is a clear or tinted protective layer applied over a sound paint system or a bare substrate such as brick or concrete. It stops spray paint and marker ink from soaking into the surface, so the graffiti sits on top where it can be removed without damaging the finish underneath.

Without protection, graffiti on porous surfaces often has to be painted over. That leaves patches that do not quite match the surrounding wall, and over time a facade can end up covered in mismatched squares that look worse than the original tag.

Sacrificial coatings

A sacrificial coating is designed to come off with the graffiti. The tag is usually removed with a pressure washer, taking the coating with it, and that area is then recoated. Sacrificial systems tend to suit masonry, brick and heritage surfaces where a breathable, low sheen finish matters, but each removal means reapplying the coating.

Permanent coatings

A permanent or non-sacrificial coating stays on the wall when graffiti is cleaned off with a suitable remover. These systems suit areas that are tagged often, because the protection does not need to be reapplied after every clean. They can change the sheen or appearance of a surface, so a test area is worth doing before the whole elevation is coated.

Semi-sacrificial coatings

Semi-sacrificial systems sit between the two. Light graffiti can often be cleaned off while the coating survives, while heavier attacks may remove some of the coating and need a touch up. They can be a practical middle ground for mixed use sites.

Which surfaces should get an anti-graffiti coating

You rarely need to coat a whole building. The most cost effective approach is to target the surfaces people can reach and see.

Ground level walls and entries

Street facing walls, building entries, laneways and side walls up to around head height are the usual targets. Look at where graffiti has appeared over the past few years and use that pattern to decide the extent of the coating.

Doors, fences and services

Roller doors, fire doors, bin store enclosures, fences, electrical kiosks and service cupboards are often tagged because they are flat, accessible and out of sight from the street. Metal surfaces need a compatible paint system underneath, so confirm the substrate before choosing a coating.

Car parks and loading areas

Car park entries, stairwell doors and loading docks are common problem areas for both strata buildings and commercial sites. These areas also take knocks from vehicles and trolleys, so the coating needs to cope with cleaning and wear as well as graffiti.

Planning anti-graffiti coating as part of a repaint

The best time to add an anti-graffiti coating is during a planned repaint. The surfaces are already being cleaned, repaired and painted, so the coating can go on over a fresh, compatible system rather than over old and failing paint.

Write it into the repaint scope

Include the coating as a separate line item so it can be priced and compared properly. List the elevations and heights to be coated, the type of coating, the paint system it will sit over and the finish you expect. Our article on understanding the scope of work in a commercial painting estimate explains how a clear scope helps you compare quotes on equal terms.

Check compatibility with the paint system

Not every anti-graffiti product works over every paint. The coating and the topcoat should come from a compatible system, and the manufacturer's application and recoat requirements need to be followed. As a Dulux, Taubmans and Haymes accredited applicator, ATD Paint can advise on systems from each of these manufacturers.

Consider colours and finish

Permanent coatings can deepen colours or add sheen. If you are also changing colours, test the coating over your chosen colours first. Our guide to choosing an exterior colour scheme for a building repaint covers sample patches and approvals.

Removing graffiti once the coating is on

Fast removal matters. Graffiti that is cleaned off quickly is less likely to attract more, and it gives the coating its best chance of performing as intended.

Set up a removal process

Agree who will remove graffiti, how quickly and with what method. Sacrificial coatings are usually cleaned with a pressure washer and then recoated, while permanent coatings need a remover that suits that product. Using the wrong cleaner or too much pressure can damage the coating or the paint underneath.

Keep records

Keep a record of the coating type, product, colours and areas treated. This makes touch ups easier and helps the next contractor match the system. If you run a planned maintenance programme, add graffiti removal and coating touch ups to the schedule so they are handled before they become a bigger job.

Is an anti-graffiti coating worth it for your building?

An anti-graffiti coating is worth considering when the same areas are tagged repeatedly, when repainting over graffiti has left patchy walls, or when the building's appearance is important to residents, tenants or customers. For buildings that are rarely targeted, it may make more sense to coat only the one or two problem areas.

ATD Paint has been delivering commercial repaints since 2003, with more than 90 painters working across Australia and New Zealand. We work with strata managers and facility managers on commercial painting projects of every size, and we can include anti-graffiti protection in the scope for your next repaint.

Frequently asked questions

What is an anti-graffiti coating?

It is a protective coating applied over paint or bare masonry that stops graffiti from bonding with the surface, so it can be cleaned off without repainting the wall.

What is the difference between sacrificial and permanent anti-graffiti coatings?

A sacrificial coating is removed along with the graffiti and must be reapplied afterwards. A permanent coating stays on the surface while the graffiti is cleaned off with a suitable remover.

Can an anti-graffiti coating go over existing paint?

Often it can, provided the existing paint is sound and compatible with the coating. Failing or flaking paint should be repaired first, which is why a repaint is the ideal time to apply it.

Will an anti-graffiti coating change how my building looks?

Some coatings, particularly permanent types, can add sheen or slightly deepen colours. A test area on the actual surface is the best way to check the result before the full area is coated.

How do I get anti-graffiti coating included in a repaint quote?

List the areas and heights you want protected, along with any surfaces that are tagged often, and include them in your repaint scope. You can then request a quote from ATD Paint and we will inspect the site and recommend a suitable system.
