  • Where to start! First spray paint is not formulated to "paint a house." Painting a house has many steps. Paint is manufactured in "formulas" for painting on specific surfaces, wood, plastic, metal, etc. Paint is also formulated for interior v. exterior as exterior also includes UV protection. These sites will explain how to paint a house.

    I don't think you should be using 'SPRAY PAINT FOR A HOUSE. You MIGHT WANT TO GO TO A PAINT STORE AND DISCUSS THIS WITH THEM!!

    Hundreds and hundreds. Your button pushing finger will never hold up. Add to it the paint is not made for this purpose and there is paint made specifically for a house exterior, using spray cans to paint the body of a house would be a fool's errand.
    BTW, "house" is not a standardized measure. Any answer would require that you specify number of square feet that need covered.

    Way, way, too expensive doing it this way. Plus more room for error.

    Do not use spray paint to paint a house!! You can rent or purchase a paint sprayer that will do a much better job.

    I think she is asking how many cans (gallons) of paint would she need to paint her house using a sprayer. Pretty sure she is savvy enough to know you can't use spray cans to paint a house. First you need to know how many square feet (surface) you have to paint, plus any trim (which would be a different color). Once you calculate that go to Home Depot, Lowes or a paint store and ask for advice on what paint to use and how best to use a sprayer (additives, etc.). You will pay less for paint in 5 gallon buckets than 1 gallon cans. Best of luck.

    Buy all of Rustoleum stock. Don't use spray paint. Not made for house painting. Never get the proper finish. Too much wasted paint from overspray. Would take forever to get proper coverage.

    Unless your name is Banksy, the famous graffiti artist, spray paint isn't for you to paint a house. Rent a commercial sprayer and buy 5 gal pails of paint, protect all windows and trim from overspray. You must also prep all surfaces for paint.
