One of the most effective strategies against illegal graffiti is to remove it as quickly as possible and to persist in removing it every time it occurs.
The three key steps in effective graffiti removal and prevention are:
Where practicable, graffiti is always more easily removed if done so as soon as possible after occurrence and before the paint has fully dried.
The most common surface types for graffiti vandalism are:
The most important thing to remember when removing graffiti from porous surfaces is to use the correct graffiti removal solution. Solutions vary, but typically the stronger the solution, such as a chemical solvent, the faster it will dissolve or remove paint. These solutions can be bought from local suppliers in your area. The strength of solution needed depends on the type of surface the graffiti is on. It is also important to take the proper safety precautions. It is a good idea to use face shields and rubber gloves when using graffiti removal solutions. To remove graffiti from porous surfaces:
For graffiti on non-porous or painted surfaces such as colorbond steel and sign-posts the only really effective removal technique is to actually repaint the defaced area.
This involves either repainting the whole wall, or targeting just the graffitied area itself.
This means that the paint has to be colour matched to the original wall’s paint colour.To colour match the paint you need to obtain a small paint sample from the graffitied site. Then just take the sample to your local hardware store where it can be colour-matched. It is good practice to label and store any unused paint so it is available to cover repeat graffiti at the same site. To paint out graffiti incidents on non-porous surfaces:
You will find that if the graffiti is very fresh and the paint has not yet dried the graffiti can be removed using the appropriate graffiti removal solution for non-porous surfaces and some steel wool.
Note: this can only be done in the first few days of the graffiti being applied. If a texta pen has been used, methylated spirits can be effective.
Applying preventative or anti-graffiti coatings are also an effective way to prevent graffiti vandalism.
There are two types of anti-graffiti coatings:
