Deck Maintenance

Once your deck is finished and is starting to be exposed to the elements, there are several things you should be on the look out to ensure the wood continues to be properly protected. It's always a good idea to check for protruding nails and loose boards regularly. Over time you may see sap that has crystallized, commonly around knots in the wood--it can easily be removed by scraping or with a little turpentine. Try to keep the deck swept clear of leaves, which when they get wet could stain the deck surface. Before winter, remove items like potted plants and metal patio furniture to help prevent staining.

Generally, try to prevent rain from standing on the deck surface for long periods, which can lead to mildew and will compromise the finish over time. If you notice water sitting on the surface several days after it has rained, brush it off with a broom. If you live in an area that receives a lot of snow, use a plastic shovel or stiff push broom to clear the snow off the deck while it's freshly fallen.

Even if the finish is still in good shape and protecting the wood, clean your deck every year with a mild solution of Benjamin Moore's “Clean,” or a non-abrasive cleaner, to remove any dirt or mildew.

Arborcoat

If you have used the Arborcoat system (stain followed by the clear coat), check to see if the clear coat is still intact or another coat needs to be applied. Depending on the exposure, the clear coat may need to be applied every 1-2 years to keep your stain intact and deck surfaces protected. Every 6 to 12 months make it a habit to look for places where the stain may have been worn or damaged--commonly under chairs and on steps. These areas need to be touched up so moisture cannot get under the film.

that needs to be refinished. The bottom half illustrates water beading on the surface,
indicating wood that is still protected.

the thing that hurts the deck mostly is - water, but there are ways to avoid it like putting some "Laka" above the deck.
