One of the most important aspects of any painting
job, whether it be the painting of wood trim on a house or a
steel I-beam of a bridge, is proper surface preparation. Even
the best quality paint will fail over an improperly prepared
This section touches upon some of the issues
which are involved in the proper preparation of surfaces for
painting in industrial applications. Follow the links below
for important information on this topic.
Important to Prepare the Substrate
Preparation for Specific Substrates
and Standards for Surface Preparation
Any surface that is painted should have a
clean interface between the surface and the applied coating.
This is very important in order to realize the full performance
potential of the coating system. Contaminants (e.g., dirt, oil,
mildew, salts, etc) at the interface can interfere with both
the adhesion and barrier properties of the coating, and lower
the overall performance.
In industrial painting, the types of surfaces painted range
from steel and concrete, to diverse substrates such as plastic,
galvanized steel, aluminum, wood, cinder block walls, and even
road surfaces. Of course, when coating previously painted surfaces,
one must also consider the variety of weathered paints which
could be encountered, such as epoxies, urethanes, acrylics,
alkyds, and others.
