I’m installing 1×4 quarter-sawn Douglas-fir T&G over 16″ spaced front porch floor joists. To get rid of the slick surface I plan to sand the deck with 120 grit to open the pours. Should I back-paint/seal the wood? The porch is covered and faces south. What sealer, stain or finish should I use?
What product should I use to stain and seal a new douglas fir T&G deck?
