Question: how many square feet does a 5 gallon bucket of stain cover?
Answer: Divide the total square feet of fence to be stained by the coverage listed on the can. For example, if you have 1,000 square feet of fence and the stain says that 1 gallon covers 200 square feet, you would divide 1,000 by 200, which equals 5 gallons to cover the fence.
