Stain never covers as much as the label claims on real deck boards. Enter your deck size, wood condition, and number of coats to get the gallons to buy — plus the cost.
Bare, rough, or thirsty wood drinks more stain — the calculator adds a realistic factor per condition.
Most solid stains need two coats. Buy for all coats in one go, no mid-project store runs.
Estimate the stain budget before the project starts so there are no surprises at checkout.
All calculations run locally in your browser.
Finish the project right.
