May 12, 2010 | The easiest way to renew your pressure treated wood deck is to thoroughly clean it of dirt and debris. Also, make sure all the lumber fasteners are countersunk into the surface. Scrub rust marks and stains from the surface, then sand down any visible imperfections in the wood deck surface with a portable walk behind sander. These deck sanders make quick work when sanding wood decks and can be rented from your local equipment rental outlet.
If a board’s appearance can’t be revived, consider flipping the board and using the other face. If rot has set in or a plank is split, then you should replace the treated lumber deck board to ensure safety. Stain and seal the entire wood deck surface to protect it from the elements. By staining and sealing the wood surface you’ll help restore your deck’s appearance. And hopefully, for a few bucks and a little elbow grease, you’ll be able to squeeze a few more summers out of your pressure treated wood deck.
