What is the difference between long life and sacrificial anti graffiti coatings?
A long life anti graffiti coating provides graffiti protection for a ten year period. It leaves the wall with a full gloss look and enables graffiti to be removed from it hundreds of times. These coatings offer the best solution in areas of frequent attack (ie monthly). Sacrificial anti graffiti coatings are cheaper and safer to apply and are almost unnoticeable on the substrate, however they only work once.
Once you remove graffiti from them, you need to reapply the coating over the effected section. These coatings are designed to protect a substrate in case of an occasional attack (ie. six monthly).
What is the advantage of anti graffiti coatings?
Anti graffiti coatings have their place, but they are not the solution to solving your graffiti problems. They are ideal if you have your own cleaners and want to make the task of removing graffiti easy for them. A common application is coating the inside of toilet blocks and cubical partitions. Coatings are a significant investment initially and they require care with cleaning and periodic maintenance.
The graffiti still has to be cleaned from the substrate which involves a labour cost. On masonry surfaces like brickwork and concrete, it is quicker and cheaper for our team to remove graffiti from uncoated substrates.
Can you remove graffiti from masonry surfaces like brickwork and concrete?
Yes - without a trace!
Isn't sand blasting a cheaper, easier method?
Sand blasting is no longer an accepted method of removing graffiti. While it is quicker and cheaper, it causes irreversible damage to substrates and can lead to concrete cancer, problems with rising damp and brick degradation. It opens up the pores of brickwork exposing it to the elements, which causes significant problems with staining and future graffiti attack.
Are the chemicals dangerous?
All the chemical formulations used by our team are biodegradable and safe to both our Technicians and the general public. They do, like any chemical (petrol, dishwashing liquid, nail polish remover) require care when handling and should only be used by suitably qualified people.
They will not harm your garden life, and when broken down with water actually become good fertilizer for your garden.
What procedure do you use to remove graffiti?
The procedures developed by our team are all chemically based. We rely on chemically breaking the molecular bonds within the graffiti, drawing it to the surface and rinsing with water under pressure. This procedure ensures no substrate damage takes place. It works superbly on masonry surfaces like brickwork and concrete.
Should I remove the graffiti I have now, or wait and see if I get hit with more?
The fresher graffiti is, the easier it is to remove. Graffiti can get baked onto substrates via the suns ultraviolet rays making it more difficult to break down.
To deter graffiti vandals from hitting your wall further, and to ensure the greatest removal success, you are best to remove the graffiti as early as possible (48 hrs).
