Wood Stain Coverage Calculator
Stain/Finish Coverage
Calculate amount of stain or finish needed
Formula
Quarts Needed = (Surface Area x Coats) / (Coverage Rate / Porosity Factor)
Frequently Asked Questions
How many coats of stain should I apply?
One coat is usually sufficient for stain. Additional coats deepen the color but increase drying time. For topcoats like polyurethane, 2-3 coats are standard.
Does wood species affect coverage?
Yes. Porous woods like oak absorb more finish per coat than dense woods like maple. The calculator adjusts coverage rate based on wood porosity.
