4 Factors that Affect How Much Exterior Paint Usage

How To Figure Out How Much Exterior Paint You Need

Know How Much Exterior Paint to Use

Painting is one of the least expensive ways to dramatically update the look of a home, but it is still important for homeowners to stick to a budget when tackling any home renovations. Although it can seem helpful to have an extra gallon or two of paint in storage for future touch-ups, paint does not have an unlimited shelf life. Some professional painters will recommend purchasing 80% of the paint you think you will need to avoid overbuying, and different factors will affect how much exterior paint to use.

Calculate the Surface Area

Generally, one gallon of high-quality paint will cover between 350-400 square feet of primed surfaces. When figuring out how much exterior paint to use, the first number we need to figure out is the surface area of your house. That’s right, get ready for some math!

Start by measuring the height and width of one side of your home. Multiple the height and width together to get the surface area of that side, and follow this same formula for the rest of your house. If your home has triangular areas, multiple the height and width of those areas and divide by two.

Next, calculate the surface areas of your doors and windows, these are areas of your home that won’t need paint. Multiply the height and width of each door and window and subtract those numbers from the total surface area of your home. If you are painting your trim and gutters a different color, you can also measure those and subtract them from your total surface area as well.

Consider the Surface

Surfaces that are unpainted, porous, rough, or textured will require more paint than a completely flat and smooth exterior. If you are painting over brick, stucco, wood siding, or shingles, you will need at least 1.5 times more paint to cover those areas. The first coat of paint should be enough to cover over or absorb into any porous surfaces. A light second coat will help touch up your paint job for smooth and even results.

Are You Changing Color?

If your paint job involves a dramatic color change, such as going from a dark color to a light color, you will need at least two or three coats of paint per surface. This ensures the previous color does not show through the new paint and that your finished exterior is truly the color you chose.

Use Quality Paint

It’s important to consider the quality of your materials in any paint job, including when figuring out how much exterior paint to use. You will find that quality paint, although it comes with a slightly higher price tag, will go a longer way than the cheapest paint. It can be tempting to spend less, but buying low-quality paint can ultimately cost you more. Cheap paint may require you to paint more coats, or it may wear down faster and require you to repaint sooner.
