How much Bora-Care you need depends more on the size of the wood you are treating than just square footage. Also, it's the lineal footage of the wood more than square footage. Here is a link to a worksheet that you can fill out and it should give you the correct amount needed based on the size of wood you have and how much you need to treat. Typically, each gallon of Bora-Care, after mixed 1:1 with water, will treat about 1000 square feet of space, but if you have larger sized wood (for example: 2 x 8 instead of 2 x 4), then one gallon of Bora-Care may only treat 800 square feet. The worksheet should be able to get you an exact estimate.
