Interior painting and how to calculate materials

Few things are more annoying than running out of paint in the middle of repainting a wall. Have your home interior painting redone is a great way to spruce up your living space. However, it does require some proper planning if you are going to do the job right. Before beginning any painting project, it is important to figure out how much paint you’ll need, as the only thing more frustrating than running out of paint halfway through is completing your task only to find you have lots of leftover paint and nothing to do with it. It’s important to buy your paint all at once to ensure a uniform color through out the project. Even with the exact same color from the exact same company, tones and pigments vary from batch to batch!

Interior paint guidelines

Calculating how much paint you’ll need is a fairly simple task. First, you have to determine what type of surface you’ll be painting on. A smooth, even surface will require a lot less paint than a rough or very porous surface, which will soak up paint and require extra coats. Most paint contractors provide guidelines regarding how much paint is needed to cover a certain amount of square footage, but for most paints, you can assume that one can of paint will cover at the most about four hundred square feet, assuming you are putting on one coat. For rougher surfaces, you can assume a coverage of about one-hundred fifty to two hundred square feet. That said, two coats is always best to ensure a true color and a beautiful, long lasting finish whether you’re considering interior or exterior painting.

Once you have figured out how much a gallon of paint covers you need to calculate how much square footage you are trying to cover. This requires some simple calculations. For blank walls, without windows, measure the width of the wall by the height. Multiply the two numbers – this is your square footage. For example, if a blank, windowless wall is fifteen feet wide by ten feet high, you would multiply fifteen by ten, for a total of one hundred fifty square feet. If the surface is smooth, you should need less than a half gallon of paint for that particular wall; if textured, about a gallon. Of course, you need to do this for all of the walls that you are painting, and then add up the total square footage before deciding how much paint to buy. In addition, you’ll need to allow for painting ceilings, doors, and trim as well if you’re including those. All too much for you? We’re here to help.
