Hello, I am finishing up my shop walls tommorrow and I plan on using
3/8 inch plywood (already on hand). Do I but them up on each other or
should I leave some space between sheets for expansion? I'm not sure
how much plywood expands/contracts but I'm thinking that since I am
screwing the ply to studs spacing shouldn't matter since the screws
will inhibit movement anyhow. My ceilings are 8 feet and change so I
plan on using them vertically and trimming the edges so I can center
the edges on studs. Insulation is already up and I have the ceiling in
( 1/4 inch ply). Once all is in I am painting the whole thing white.
Any opinions, comments? Thanks in advance, Guy

Because the grain in the layers of plywood are laminated in a cross grain
pattern it is fairly stable and does not expand or contract much. I'd
butt the seams tight.

If you leave a gap between the sheets it will become a dust trap,
there will be enough flex in the timber to account for any expansion.

I know you said you have the ply on hand, but if it's just being used
as lining I'd be inclined to save it for something worthwhile - any
brackets and mounts you put up will go in to the studs, so I'd be
getting some 1/8 ply just for wall lining.
Cheers

It'll move, but you'll never notice the tiny bulge between the studs. Do
yourself a favor and run some fire-break type support between the studs at a
couple of levels. Note the centerline from some constant position for
future reference. Makes it easier to hang heavy stuff in the future when
you know where they are.

Butt them together, then a coat of primer and a coat or two of bright
white and the inside will look like National Lampoons Christmas. Only
diff between yours and mine is I used 7/16 OSB - before the prices
skyrocketed!

When you go for paint, lighting people recommend either flat or
eggshell, they say that gloss causes glare.

Sheet rock is cheaper, and doesn't burn nearly as easily as the
plywood.

Moot point if the whole shop is full of wood and shavings.

Hi Guy

I have 3/8" plywood as inside walls in my workshop, they are but
together, and that's just fine, make sure you have some extra electrical
outlets and like George said have some horizontal bracing in so you are
able to hang/attach some stuff to your wall when necessary.
As for the painting, mine is only sealed and left wood grain, if you
want to paint, high gloss is the strongest paint, and easiest to clean
and keep clean if needed.

Have fun and take care

But one wrong move and you have a hole in it, plus its not good for
mounting tools and other things in a pinch.
