Pressure washing: It is to keep exterior surfaces
free of mildew and moss etc. Airborn spores stick to any porous surfaces
and begin to cause damage to paint and masonary as their roots develop
and become embedded.
The first step is to apply a mild bleaching agent and
T.S.P. to the surface affected prior to pressure washing. Next step,
after allowing the solution to penetrate for at least 1 hour pressure
washing can be started.
Equipment: We use a 13 h.p. Honda pressure
washer, which can provide 4,000 P.S.I. This is more than adequate for
our industry to insure that all contaminants are removed from the
surface.
