I'm putting up a plywood wall in my garage workshop and have some unsightly seams; 1/8" or less gaps except around floor where I plan on installing baseboard anyway. I've had to cut smaller segments of plywood to work around some workbenches installed by the previous owner so there's vertical and horizontal seams, if that matters. I plan on painting the wall when finished but wondering what would be best to use to fill in/cover the seams before painting.
The overwhelming consensus here seems to be standard painter's caulk so marking this as answered. Thanks to all that responded.
The most astheticaly(sp) pleasing way to cover gaps in a plywood wall with flush results is to glue up a veneer on the gaps. caulking, silicone, anything else will be ugly, dirty, and eventually fall out.
