I guess I really don't know why my shop would have more moisture probles, I
have floor drains,cement floor and vapor barrier between the insulation and
the tin siding.

There is a board for moist areas. Any drywall or home supply outlet
will
have it. As for the plywood, it may not meet building code unless
there
is
drywall under it. In a shop, plywood is nice in that you have one
very
large tool board.

A good thickness of drywall will also let you hang "stuff". Good
forbid
but if there is a fire, the wall board will definitely keep in one one
side
or the other for a hour.


Do you recall what this board is called and an approx. price per sheet ?
Also what do I have to cover it with to keep it from absorbing and liquid
that gets on it ? Do I have to paint it or seal it ?
Thanks,

There's "greenboard", which is your basic drywall with a water resistant
paper.
Better than regular drywall for the occasional splash, but will break down
under
continuous wet just like standard drywall.

There is also concrete board (Durock / Wonderboard). It'll handle water
a lot
better than greenboard or regular drywall (it's the backing material of
choice
in tiled showers and such).

What sort of water problems do you anticipate? Shoot, most garages are
just
done up with 3/4" drywall. Why would this "shop" have larger moisture
problems
than a garden-variety garage?
