Deck refinishing depends on the condition of the deck and the type of wood. Sanding and cleaning prepare the deck for stain penetration and adhesion to the wood. We refinish all types of wood from softer woods like cedar and redwood to hardwoods like Ipe, Brazilian Redwoods and Cambara.
Preparation , the start to a great finish:
Refinishing and maintaining your wood is our specialty and gives us the most satisfaction, when we take a weathered deck and turn the gray wood into a deck you envision.
Why you have to prepare:
Exterior wood surfaces are exposed to a variety of harsh elements including UV rays, moisture, and foot traffic. Damage to the three main components of wood (Lignin,Cellulose,Hemicellulose) depends on either cleaning or sanding or both will be needed for the proper preparation for your deck.
When cleaning is the correct alternative:
The first procedure is removing the dirt from the wood surface utilizing a cleaning agent followed by a low pressure rinse with water resulting in a clean surface. A wood brightener is applied to remove discoloration caused by tannin bleed,nail or screw rust stains and a neutralizer to restore a rich new wood look.
High pressure cleaning must be avoided the procedure will raise grain and increase the amount of damaged wood cells. A fungicide may be applied if mold or mildew is present. The wood must be completely dry before staining (moisture content below 18%).
When sanding is the correct alternative:
The first procedure is to check the countersinking of deck screws. Deck screws have a coating to protect from rusting if the protective coating is removed by sanding the screw is susceptible to rust. The correct grit of sandpaper is the next decision. When a new deck is to be finished the removal of a mill glaze is necessary before staining and lighter grit sand paper would be used. If your wood surface is older and is rough,uneven, splintered or raised grain a heavier grit would be used first followed by a lighter grit for a smooth surface.
Choosing the correct type of stain will depend on many factors. Stain must be water repellent, provide protection against UV ray deterioration, last against wear and tear,flexible for expansion and contraction of the wood, are microporous to allow moisture in the wood to escape and contain a fungicide. Depending on moisture, sun exposure and foot traffic the type of stain you decide on will dictate the frequency of finish maintenance. Each of the below listed stain types will meet variables of your needs.
Translucent or transparent stains-lightly pigmented stain with limited color selection results in a rich natural look highlighting your wood grains,meanwhile offering protection from moisture and UV rays. This stain will protect your horizontal wood 1-2 years and vertical wood for 2-3 years.
