The Deck Stain and Sealer Calculator computes the number of gallons of deck stain and sealer needed to cover a deck, porch or steps.
INSTRUCTIONS: Choose units and enter the following:
Deck Stain and Sealer (DS): The calculator returns the gallons of stain needed to coat the deck area. The calculator also returns the surface area (A) of the deck in square feet. However, these answers can be automatically converted to compatible units via the pull-down menu.
The surface area of a deck is based on the length and width. The surface conditions dictate the amount of stain needed. 400 ft2 to 500 ft2 of smooth surfaces can be covered with one gallon of stain. Only 200 ft2 to 300ft2 of rough surfaces can be covered with a gallon of stain.
Stain typically takes four to six hours to dry. Do not place furniture on newly stained deck for at least twenty four hours.
Stain only works if it can penetrate into the material. This means that the material should be free of loose fibers, oils and organic material such as mildew. Power washing, sanding or the use of a wire brush or scraper can often effectively remove unwanted material. However, be sure to sweep off removed material, and in the event of power washing, allow the material to thoroughly dry to make it permeable to the stain.
