Introduction Part 1: Identifying
Substrates - One of the most important tasks for
a painter is to be able to correctly identify
surfaces and substrates. Without proper
knowledge of surface and substrate types, it
would be difficult to choose compatible coating
systems. This course covers failures of paint on
interior and exterior substrates and their
remedies. You'll learn about the special
characteristics of the substrate, for example,
painted, hardwood, softwood, alkaline and
non-alkaline, how to prepare the surface, and
which primer's and topcoats are appropriate for
the surface/substrate and it's environment.
Paint is only as good as the surface to which it
is
applied. A properly prepared surface, paint
selection and application will provide a
professional paint job!
Part 2: Paint Failures & Remedies—As a member of
the painting trade, you will often be called
upon to correct finish problems. It is important
that you be able to determine what caused a
problem so that you can both correct it and
prevent it from recurring. If you are not able
to do these things, your work will suffer. You
may also find yourself in a situation where you
take the blame for a failed finish when the
problem was caused by something outside your
control. This module will cover problems related
to adhesion on interior and exterior surfaces.
Knowledge is a powerful tool and if you
understand how a problem occurs then it is much
easier to determine the solution.
Description Covers how to identify
types of surfaces used in construction
including wood, metal, masonry/concrete,
plaster/
drywall and synthetic substrates. Also discussed
how to
identify new, aged, or previously coated surface
conditions
of substrates. Also covers failures of
paints/coatings
on exterior and interior substrates, causes of
these
failures, and their remedies. Focuses special
attention
on the nature of the substrates, application
procedures,
and surface preparation.
