Technique can make all the difference when removing graffiti from a surface. Whether it be brick, wood, metal or plastic the end result can depend on how you approach it.
Simple Method: Porous Surfaces (Such as concrete, bricks, blocks):

- Scrub surface with a nylon hard bristle or wire brush, to break the seal.
- Apply graffiti removing product, with sprayer or paint brush.
- Wait a minimum of 3 minutes.
- Scrub surface again with a nylon hard bristle or scourer. NOTE: different scrubbing tools work better than others, try using various tools to find what works best on your surface.
- Repeat steps 2 to 5, keep area wet with graffiti removal product, until all graffiti is loose.
- Remove chemicals with a hose or high pressure water blaster (preferable), working slowly back facing
the wind at a 45ยบ angle, approx 20 cm away from the surface up to 3000 psi. - If shadow exist repeat process.
- Coat surface with a semi sacrificial surface graffiti protection, to make it easier for future graffiti removal.
Method for Sensitive Surfaces (Such as colour bond):
- Dry surface (most graffiti removal products work best on dry surfaces)
- Clean surface with a white rag.
