Male Speaker: Is your deck looking worn and weathered? Don't replace it, rescue it with wood resurfacer.
Before applying the wood resurfacer be sure to take the proper steps to prepare the deck. There should be no threat of rain for at least 24 to 48 hours, and both daytime and nighttime air and surface temperature are between 50 and 90 degrees.
Secure any loose boards, thoroughly wash with a deck cleaner, and then pressure-wash in a low-to-moderate setting.
Allow the deck to dry completely at least 24 hours, then sand any loose wood fibers, remove sanding dust and crock any cracks deeper than a quarter inch. Cover and tape off any areas such as exterior walls to protect from drips. It's a good idea to start with vertical surfaces such as the rails and posts, so that the drips will not land on previously finished areas.
You can use a wood resurfacer or a stain. Once vertical surfaces are complete, start on the deck boards. Thoroughly stir the resurfacer than pore a generous amount into a roller tray. Use a brush to apply the resurfacer between decking boards. Dab into any quarter-inch deep cracks, nails or screw holes or nuts until the hole or crack is filled, and cutting around the edges of the entire deck surface using short dabbing strokes. Be sure to treat all areas of the wood including the joints, edges and ends of the boards.
Then fully saturate a half-inch nap roller by rolling back and forth in the tray. A fully loaded roller will ensure cracks are filled. By using slight and even pressure apply the resurfacer to a few boards at a time. Keeping a wet edge to avoid lap marks, some decking boards will be warped or cupped.
To ensure the coating is driven into the cracks, roll across the narrow width of the board as well as the length of the board in these areas. Lightly brush any product that drips between the decking boards. You can also back-brush after rolling on the coating for a smoother appearance.
Allow a minimum of six hours for the first coat to dry. To apply the second coat, cut in with a light dabbing stroke around the edges of the entire deck surface. Dab the product into any of the cracks, nailers, screw holes, and nuts that will need to be filled. Then repeat the same steps from the first coat.
Allow the final coat to dry at least 72 hours before replacing furniture or heavy objects such as potted plants, then sit back and enjoy your newly resurfaced deck.
