Copper Painting

In most instances Copper and Copper alloys
do not require painting. The inherent
properties of Copper resist corrosion and
biofouling. Painting of Copper is
occasionally done for aesthetic reasons. It
is also done to reduce the incidence of
metal to metal contact of bimetallic couples
where galvanic corrosion might be a
problem.
Before painting Copper, the surface of the
material should be roughened by grit or
sand blasting. Other specific procedures will
depend upon the type of paint being used.
Please consult the paint manufacturer for
details.
