The average cost to paint a house exterior is $2,500 for a 2,400 sq. ft. two-story home, with most homeowners paying between $1,800 and $3,200. The final cost comes out to around $0.60 to $1.60 per square foot. With so many variables in pricing, you need to take them all into account before coming to your own estimate on how much your painting project will end up costing.
An example of the wall measurement would be: 40 linear feet of bedroom space, x 8 wall height, = 320, x 2 = 640. Minus 1 door (60) and 2 windows (80) = 500 sq feet being painted. Then divide the 500 by 400 (sq feet per gallon), and you get 1.25 gallons (4.73 L) needed for that room. For this, you'd need 1 gallon (3.8 L) and 1 US-quart (950 ml). If the amount it comes out to is over 1.3, we recommend just getting 2 gallons (7.6 L) so that you have leftovers if needed, since 2 US quarts (2,000 ml) costs essentially the same as a gallon in most stores.

Priming - $30–$40/hour for labor. Many of the materials above need to be primed, but not all do. If you’re changing paint colors from dark to light or light to dark, use a color similar to the top coat. That way you’re less likely to need extra coats over the standard two. Prime with a flat or eggshell paint. You can ask your paint store to add tint to the primer to match it with the top coat color. Hammer in exposed nails and spray them with a metal primer to prevent rust. House Painters Louisville
