“Last Chance” Coatings for Outdoor Decks


If your outdoor deck is on its very last legs, there may still be a way you can save it: by applying one of the super-thick coatings that help restore, as well as refinish, weather-beaten decks. Made to help rescue endangered surfaces of all kinds, these special coatings actually fill in and help conceal cracks and crevices up to ¼-inch deep. They come in a wide range of attractive colors, and they create a slip-resistant finish that resists future cracking and peeling. They are all designed to give downtrodden surfaces new life.


Assuming that your deck is made of wood, start your project by carefully inspecting its condition. Replace any boards that are rotting or unstable, and sand any surface where the wood is splintered. Next, thoroughly clean the entire deck, making sure to remove dirt, mildew, and any stains that may be present. You can do this either by power-washing the deck or by using a commercial deck cleaner.


As you might expect, super-thick deck coatings cover fewer square feet of surface than deck stains – often, only about 75 square feet or so per gallon. For that reason, it’s wise to mix together several gallons of product in a large paint container. That way, you’ll be sure to have consistent color on your entire deck.

Begin your application by using a synthetic-bristle brush to spot-fill nail holes and cracks in the wood. If the openings are deep, this may take two applications. Also use the brush to apply the coating between boards, in tight corners, and on the edges of your deck.


For the bulk of the surface, use a long-handled roller to apply a generous, even coat of the product. If your wood has hairline cracks, or if you just want to give your deck added protection, use a ½”-nap roller to apply an extra-thick coat. Otherwise, a ¼” roller may be sufficient.


If you are also applying the coating to vertical surfaces, use a brush or roller and apply a slightly thinner coat. This will help prevent a gravity-induced “sagging” effect in the appearance of the coating.


For optimum performance, it’s always wise to apply a second coat to every surface. In ideal weather conditions, some super-thick deck coatings may dry in as little as six hours, but it’s best to wait at least 24 hours before applying the second coat. Be sure to check the label for dry time and other instructions.


What if your deteriorated surface is something other than a wooden deck? Many super-thick coatings can be successfully used on not just wood but also composite surfaces and concrete too for everything from porches and patios to pool decks and boat docks.


The quality of the product you choose is not something you want to compromise on for your deck coating. Acrylic coatings have several advantages over oil-based coatings, so take that into consideration when choosing your product. Also, higher quality products should last longer and save you money in the long run since you won’t have to repeat the project as soon as you would after using lower quality products.


Save your deck with a super-thick deck coating. Choose the right product for you taking quality and color into consideration. With the proper preparation and application, you should be able to enjoy your deck for years to come!
