Traditional graffiti removal methods like chemicals and soda-blasting are not safe for the environment, killing surrounding vegetation.
Pressure washing, chemical stripping, soda blasting, and sandblasting can destroy brick and remove mortar from walls. These methods also have poor production rates. This coupled with the damage to the sub-surface make these methods ineffective.
Vapour Blast systems were built with a wide range of pressures to be utilised on gentler surfaces like brick, so paint can be stripped while protecting the sub-surface. Vapour Blasting can also remove paint layer by layer, so you can remove graffiti effectively even from painted surfaces like metal or wood signs.
