28000Re: Plywood checking on Brucesboat
- Jun 22, 2013The air temperature in the shade (garage) is not the same as what the
surface temperature of something might be getting up to in bright direct
summer sun. Depends on how dark the surface is of course, but it can get
up to twice as high as the air temperature in the shade and can soften
or even wipe out epoxy as Chris mentions. Plus the UV affect and the
temperature fluctuation over night if you live at higher altitude or in
a semi-arid climate. And the wetting and drying cycle when it rains can
all add up to significant accelerated weathering of plywood. And pine is
the most affected as it has alternating soft and hard rings.
A good cover is really worthwhile for a wooden boat and not just the
open designs. And a good cover takes some effort and money to construct
and fit. Blue polytarp secured with a few bungie cords just won't do it.
I badly damaged 2 boats that way.

my garage here in Aurora, CO. Day temps in the summer are well over 100
in the garage. Heat I don't think effected anything other that I had to
use slow hardener and still needed to have the game plan down as soon as
it was mixed. I had pots start heating up on me within 12 minutes a few
times. Anyways the boat turned out great as a matter of fact the wife
and I are heading to the lake in about an hour or so. Heat...not a
concern...everything else you mentioned does need protection especially
direct UV exposure.
