The floor of my deck is old and needs replacing/refinishing. It is 2X4 on 24in centers. It is 40ft by 12ft (3 to 8 feet off the ground) so replacement price is a consideration. I've considered dividing it into sections and removing 3 out of every 4 2x4s then putting regular 1x6 deck flooring on the 45 degree diagonal. I could always just replace with treated 2x4s but would like to change the look. Also, is it feasible to resurface (sand) the existing 20+ year old 2x4s to get a clean, uniform surface and restain (solid color)?
Any thoughts would be appreciated. Thanks.
