Removing
graffiti from the surface of masonry building materials could
be a difficult task because mineral masonry surfaces are rough,
allowing easy adhesion of graffiti paints. A powerful (but
generally toxic) solvent or solvent mixture must be used to
remove the graffiti. Tech-Dry Biodegradable Graffiti Remover
(BGR) is a unique blend of completely biodegradable, low odour
and low toxic materials, which effortlessly removes graffiti
from most surfaces.
To
avoid using solvents or graffiti removers to remove the graffiti,
the masonry surface can be pre-coated with a sacrificial graffiti
coating No More Graffiti (NMG). The graffiti can be removed
by using hot water.
