Most municipalities and facility managers start their graffiti search the same way. They look for graffiti removal products, sprays, chemical strippers, pressure washing services, anything to get a wall clean fast. Initially, that search makes sense for a single incident. However, it becomes an expensive habit once graffiti keeps returning to the same wall, bridge, or underpass.
The Real Cost of Graffiti Removal Products
Chemical strippers and specialist sprays work well on a bare, unprotected surface. Consequently, they form the first line of defence for most facility teams. However, the problem shows up on the second incident, and the third, because an unprotected surface offers no resistance to the next tag. Furthermore, each removal cycle repeats the same chemical purchase, the same labour, and often the same surface damage.
Repeated pressure washing and solvent use also wear down concrete, brick, and masonry over time. As a result, municipalities pay twice, once for the removal product and again for eventual surface repair or repainting. Consequently, budget line items for graffiti removal rarely shrink. Instead, they simply repeat every time a new tag appears.
Why Permanent Coatings End the Cycle
A permanent, non-sacrificial coating changes this pattern entirely. Unlike a sacrificial coating, which washes away with the graffiti during removal and needs reapplication afterwards, a permanent coating remains bonded to the surface. Therefore, the same protective layer works through every future incident, not just the first one.
This distinction matters most for high-exposure sites. For instance, bridges, underpasses, transit stations, and municipal buildings face graffiti repeatedly, often within weeks of a clean-up. As a result, a sacrificial approach forces facility teams back into the same purchase cycle, while a permanent coating breaks it.
SI-COAT 528AG: The Permanent Alternative
SI-COAT 528AG is a single-component, room-temperature vulcanising silicone coating from CSL Silicones, an ISO 9001:2015 registered manufacturer. TSS distributes it exclusively across South Africa, Zambia, DRC, Tanzania, and Namibia as CSL’s Sub-Saharan Africa partner.
The coating bonds chemically to the host surface, so it needs no abrasive blasting and no primer on most substrates. It suits metal, concrete, brick, stone, wood, fiberglass, and pre-existing coatings, which covers most municipal infrastructure types. Application uses airless spray for large areas, or brush and roller for smaller sections.
Once cured, removing graffiti requires nothing more than a cold water pressure wash at 1,200 psi. No chemical solvents enter the process. If graffiti sits for more than 10 days, a warm water pressure wash usually clears it. In rare cases involving specialty paints cured for extended periods, a biodegradable surfactant with a cleaning pad lifts the remainder, followed by an immediate rinse.
The coating becomes tack-free in 80 minutes and reaches full physical characteristics within 7 days. Furthermore, every colour undergoes 5,000 hours of accelerated UV weathering testing, so appearance holds up over years, not months. In addition, low VOC content of 70 grams per litre meets California SCAQMD standards, a global benchmark for environmentally responsible coatings.
What Permanent Protection Means for South African Infrastructure
South African infrastructure carries real financial exposure to graffiti and vandalism. PRASA alone has absorbed over R7.64 billion in theft and vandalism losses across five years, with over 80 percent of stations damaged during COVID-19 lockdowns. As PRASA restores 40 rail corridors, every newly restored surface becomes immediately vulnerable again without protection.
Cape Town’s CCID manages graffiti removal as a permanent operational service, not an occasional task. Consequently, this confirms what facility managers already suspect: graffiti removal products are not a one-time purchase. Instead, they are a recurring cost line that never closes.
There is a secondary benefit worth noting for facility teams managing underpasses, stairwells, and station walls. SI-COAT 528AG’s hydrophobic, non-porous surface does not allow liquids to soak into the substrate underneath. In addition to blocking paint, this same property helps concrete and brick resist staining and odour absorption from other liquids that commonly affect high-traffic public areas.

Frequently Asked Questions
Are graffiti removal products still needed once a coating is applied?
No ongoing chemical products are needed once SI-COAT 528AG cures. Cold water pressure washing at 1,200 psi handles standard graffiti removal without solvents.
How is a permanent coating different from a sacrificial one?
A sacrificial coating washes away with the graffiti during removal and needs reapplication. A permanent coating like SI-COAT 528AG stays bonded to the surface through repeated cleaning cycles.
Does SI-COAT 528AG work on concrete and brick infrastructure?
Yes. The coating bonds to concrete, brick, stone, metal, wood, fiberglass, and most pre-existing coatings without abrasive blasting or a primer on most substrates.
How long does the coating take to cure?
The coating becomes tack-free in 80 minutes. Full physical characteristics develop over 7 days, though surfaces return to service well before that point.
Is SI-COAT 528AG suitable for municipal and transport infrastructure?
Yes. Its temperature stability, ranging from minus 60 to plus 200 degrees Celsius, and its UV-tested colour durability suit bridges, underpasses, stations, and other exposed municipal assets.
