Wood Stain Coverage Area Calculator

gallons = area · coats / coverage_per_gallon.

Compute the gallons (and quarts) of wood stain needed for a deck or fence. Wood absorbs more stain than paint; typical coverage is 200 sq ft/gal for smooth wood and 150 sq ft/gal for rough/weathered. Adjust the coverage field per the stain manufacturer's spec sheet.
