Stain Coverage Calculator
Tell it the area and the product, and it sizes the job from that product's real label coverage - not a rule of thumb.
How to use it
Choose inside or out, enter the square footage, and pick your stain. On a water-based system, say whether it's bare wood or a maintenance re-coat.
What you'll get
Gallons for the stain and its top coat, the cheapest way to buy them, any additive quantities, and the recoat cycle that product's label calls for.
Label rates, not guesses. Wood porosity still matters — every label gives a range, and we're happy to sanity-check by phone.
