Using a sealer for waterproofing deck or staining a deck will greatly expand the lifespan of any hardwood deck. The finish keeps the wood from experiencing wetting and drying cycles. If left unstained, precipitation enters your deck and expand. Once the wood starts to dry, it contracts. This process of contraction and expansion results into the degrading of your deck. Sealing will prevent the water from getting in and thereby greatly cutting down the drying and wetting cycles.


Benefits of applying a deck finish

Periodically using an ultraviolet graded deck finish prevents you deck from the so-called 'graying' of the wood.

Applying a deck with periodical coatings of a deck finish will also prevent the deck from checking, splintering, warping and degrading.


When to apply a finish

Late reports by the Forest Products Laboratory (FPL) of the USDA show that deck and lumber in general can be coated shortly after construction. Always assure yourself from the instructions on the can since some deck finish products may urge some time to wait before applying.


Periodical coating of a deck finish is essential to protect your deck from degrading. The length between coatings varies upon the type of finish and the way your deck is exposed to the elements such rain, shade or full sun. Most decks are better be cleaned, sealed and finished between every 1-5 years.


deck sealing drying time

Be sure the wood deck is dry for several days prior to applying a deck sealer. If you are not sure, check the wood moisture content with a special meter. Apply the finish only the moisture content of your deck wood is beneath 20%.


To apply the deck finish you should wait for dry weather. Once applied the deck finish, most deck sealers require 24 to 48 hours of drying. A humid day will extend the drying time and rain can cause finishing defects of your recently sealed deck. So your weather forecast will interfere with your plans when to seal your deck.
