This story takes you through the process of preparing your deck for a clear finish and applying the finish.
Home centers offer a wide array of deck cleaners, sealers, and finishes. Check with deck owners in your area to see which products work best and how often they need to be applied. If the deck is exposed to hot sun for extended periods, you may need to apply a fresh coat of sealer every year.
A deck that has turned gray can usually be made to look like new if you wash it and apply a protective finish. Even grayish-green pressure-treated wood can be stained to resemble cedar or redwood.
It may be worth the cost to hire a professional to finish or refinish your deck. Look through your phone directory for companies that restore, finish, and maintain a deck's appearance. Check out their prices and examine some of the decks they have worked on. Compare the cost with the time and expense it will take you to do it yourself.
