Deck Stain Calculator
This deck stain calculator is meant to give you a general idea of how much deck stain and deck prep products to buy. There are various factors that will affect coverage including, the age and type of the wood, the porosity of the wood, as well as which deck stain you use. Keep in mind that the recommendations below are estimates.
Note: The amount of product recommended has been rounded up to ensure you have enough to complete your project. As far as this calculator goes, if a stain covers 100 sq. ft., and your deck square footage is anywhere between 101-199 sq. ft., it will recommend you buy 2 gallons. This is just a safeguard so you don’t run out of product mid-project. Keep this in mind when using this calculator.
