how much square footage can a gallon of paint cover
Once you know the total square footage you need to cover, you need to find the coverage ratio of your paint. Most professionals use the formula of 350 square feet of wall coverage per gallon of paint and 200 square feet of wall coverage per gallon of primer. Itâs important to note that different types and manufacturers may cover more or less area, and different application methods, eg. spraying vs. rolling vs. brushing, will cover differently.
