Hey guys about to start finishing a wood slab (Eastern White Pine) that is 2" thick and is a length 8 feet as a bartop. The bar will be in a detached garage, so it really fluctuates in temps and conditions depending on the time of year up here in upstate NY. My question would be this, I am concerned about wood movement, I have slotted screw holes in the frame to allow for movement during the year. I was thinking of sealing and flood coating the top and edges with a self leveling two part epoxy, and possibly an oil based Spar Urethane on the bottom of the wood slab. My concern is if the epoxy will restrict thewoods movement.Possibly over thinkingthis, but also wanna be sure before I proceed forward.If epoxy is not the way to go, what would youall suggest is the best way to proceed.
