This is common in colder climates where you see
ice and snow accumulate by doors and entrances.
After the winter we had (35 yr record snowfall and
cold temperatures), moisture and ice can cause
considerable damage that goes beyond warranty
considerations. Remember, an average coating film
thickness is thinner than a human fingernail and is
expected to elongate and contract as much as 180%
during its lifetime.

We stand behind our preparation techniques and application
skill and knowledge of how wood and steel reacts to exterior climate
conditions, we always recommend the best product for the
project, however we cannot control a 5 year envelope
of weather conditions. Repaint cycles on exteriors in Canada
averages anywhere from 24 to 36 months as we do have
the most aggressive temperature variations in the Northern
Hemisphere. 40 below in winter and almost 40C in summer...!

You have to look at exterior coatings as sacrificial in nature, they
protect the underlying substrate and will eventually fail themselves,
however they have succeeded in protecting that surface in decaying
or aging prematurely. Doesn't matter if your spraying a tank farm
with high end epoxy/polyurethane topcoats for a 10 year duty
cycle or you are spraying exterior window sills and jambs...the
fact is the COATING is providing protection to the substrate
and that is its core function.
