The beauty and function of a wood deck is well known to many homeowners. Unfortunately this beauty is somewhat short-lived before it is time for deck refinishing.
A maintenance schedule of 1-3 years is a good choice for most wood decks. The amount of longevity possible from a deck finish is dependant on initial preparation, choice of deck stain plus exposure to intense sunlight and weather. Preparation is 75% of the work.
Proper surface preparation prior to applying the finish is absolutely critical and can never be overlooked. If you choose to hire a deck-refinishing contractor make sure proper preparation is part of the contract.
Before any washing or sanding can take place all mold, mildew and other "infections" need to be dealt with. It makes no sense to apply any finish over this damaging nuisance; sanding mold will simply grind the fungus deeper into the wood and cause it to rot from the inside out.
To remove mold from any deck surface wood brightener or deck cleaners can be used. The choice depends on the amount of preparation you will be doing. Wood deck cleaners will be fine with additional sanding. Bleach and water can be used when small areas are affected.
Evaluate the condition and stability of the wood and stain. Many stains "burn off" and turn into powder after a short time and can be removed with water. Deck cleaning can also include the use of wood strippers or brighteners. These chemicals are an interesting addition to power washing, but not necessary.
When refinishing a deck, power washing is just one part of the preparation process. The most important part is sanding. Deck sanding is a labor-intensive job and should include the use of power sanders.
Sanding can occur before the washing if the deck is very rough and requires a lot of work. In this case washing is used to clean the surfaces of dust and open the pours in the wood, allowing deep penetration of the stain.
Wood decks that are in good shape can receive a light sanding after a thorough power washing.
After all surfaces are clean and sanded a penetrating deck sealer needs to be applied. There are two general types on the market: lightly tinted and solid color. Your choice depends on the needed longevity and overall desired look, a general rule is the more color the longer the lifespan.
The most popular methods for applying a wood deck stain are with a brush, roller, a paint pad or spraying. The best method depends on experience and the decks construction.
Refinishing a wood deck can be a difficult and exhausting task. Especially if the deck has been neglected for a while. Contact a deck specialist located in Kitchener/Waterloo on KW Contractor.com. When the deck is properly refinished a maintenance schedule can be established. A proper wood deck maintenance schedule will reduce the need for intense preparation in the future.
