If you treat your deck annually, you probably won’t be asking yourself this question. But if you’ve been lax on upkeep or perhaps have bought a home with an existing deck, there are ways to bring it back to life. Often times, you can rejuvenate life into an old deck. Some decks can get badly discolored. If you wait too long to treat the wood, it can become damaged beyond repair and you will have to live with what you have or rebuilt your deck from scratch.
Before treating your old deck, take some time to clear the surface from all loose dirt and debris. Using a broom and a pressure washer, remove as much dirt as possible.
There are two different types of deck treatments. There is a water repellent preservative that adds a clear finish and protection to the wood. These are often a wax or silicon base. These products seal the wood surface but don’t soak into the wood as deeply as an oil stain. This type of deck treatment should be reapplied every year. Be sure that the label says their product will protect your deck from mildew, water, and UV rays.
Then there is a semi-transparent oil stain. This one also lets the beauty of the grain show through but adds a hint of color in the stain. This type of finish usually lasts longer than the transparent treatment but how often you need to reapply will depend on the area you live in and the conditions the deck is exposed to.
