As a point of note you should be aware
that to epoxy is 100% ok on any (old)
wood surface...
however (yes there is always a but)

The other side of the wood/planking/ply
should NOT have any epoxy/poly material
applied other than the usual painting to
allow the wood "to breath", thereby in
most (not all) cases preventing that
nasty old boogy called ROT to set its
ugly feed in!

Well....in an ideal world, or a laboratory.
Any exposed wood will absorb the humidity in the air, so at best the wood
will be around 12 % moisture content. Whether you paint,varnish, epoxy or
heavily oil on all sides you will (especially on the end grain) be
effectively sealing in the moisture content. As long as you are at 12% or
less this does not pose a problem. Some species of wood will respond
differently of course. Sealing all surfaces stops the uptake of moisture
during wet winter weather. I do agree with you that sealing in a high
moisture content is excercising poor judgement.

I know some folks do it that way (seal one side), but it disagrees with what
the epoxy manufactures say, what Gougeon Brothers say, and others. The
existing moisture in the wood will get trapped on 'surface states' in
between the wood and epoxy. Rot organisms will then have all that they need
....food (wood), oxygen (unsealed wood 'breathes' as you say), and water
(trapped at the epoxy/wood boundary). Not on my boat...

I don't think a teak deck will rot. Period. But I could be wrong, of
course.

Teak is a great wood .... but it is wood.
I have an all teak house I built in North Thailand 16 years ago. Where the
wood is protected or fully exposed it is as good as the day it was cut.
Where the porch meets the walls and where water collects with less air
drainage it has become rotten.
Still....one of the best, rot resistant light hardwoods.

Well, I still don't think a teak boat deck will rot, even if it were
fully encapsulated in epoxy, unless it is just utterly neglected and
poorly designed to begin with.

But your point is taken. All materials have their limits. ;-)
