Once you have the interior square footage calculated, experts say you’ll want to divide by 350. 350 square feet is the average coverage of a gallon of paint (though some say 250-400 square feet). The average coverage for a gallon of primer is 200 square feet. Your square footage divided by 350 square feet gets you the number of gallons of paint you’ll need. Square footage divided by 200 gets you the number of gallons of primer you’ll need. You can save money by ensuring you don’t buy too much paint.
Once you’ve got a small area covered, you’re ready for step two, laying off the paint (Photo 3). First use your brush to spread the paint evenly over the surface and then finish up with long, continuous brush strokes. The goal is to completely cover (but not necessarily hide) the previous layer of paint or primer with a smooth, even layer of paint. This step must be done immediately after the paint is laid on and before the paint starts to dry. Home Painters Louisville CO

Painting siding that has never been painted before, whether it is newly installed wood siding or vinyl siding being painted for the first time, will require a primer. Paint should not be applied directly to bare wood, while some materials like vinyl need a primer to bond the paint to the surface. A few materials, such as fiber cement and some engineered woods, may arrive pre-primed and ready for painting, which can save time and money on the project.


Each type of siding will need to be treated differently when it comes to primer and paint at different price points. Exterior paint costs between $35–$80 per gallon depending on the quality you choose. It’s not always true that the more you pay for your paint, the longer-lasting your paint job will be, but you do need to be careful when researching exterior paints to make sure it can weather the local elements well.

The goal of the first step, called “laying on” the paint, is to get the paint onto the surface in the quickest, most efficient way possible. Don’t worry about smoothing it out yet (Photo 2). Use a brush, roller or sprayer for this step and apply enough paint to cover the surface without creating runs. Cover an area just large enough to allow you to go back and smooth it before the paint starts to dry. Since heat, humidity and the type of paint you’re using all influence drying time, you’ll have to experiment as you start to paint to get a feel for how large an area you can safely cover before returning to smooth it out. The most common mistake beginning painters make is spending too much time and effort laying on the paint. A few quick strokes is all that’s needed. Then reload the brush and cover the next area.

Supplies and Equipment – Scraping, sanding, and stripping tools and supplies; patching compound; power washer rental; primer; caulk; masking supplies; painters’ tape; ladders and scaffolding; paint pans; brushes, sprayers, and roller brushes all cost money, even if you do it yourself. Consider all of those tools and equipment sitting in your garage for the rest of your life vs. paying an experienced painter to do it all for you at a price that saves you weeks of time. Expect to pay $5–$6 per 100 sq. ft. for supplies and materials. Louisville House Painting
Painting exterior windows depend on the size of the window and the number of panes. To calculate the price for windows larger than 15 sq. ft., add 1’ to each side of the window and then multiply width x length. Add two sq. ft. for each window pane for painting the mullions, muntins, and sash and then multiply your total sq. ft. by $84/100 sq. ft. So a 4’ x 4’ window with 4 panes will come to a total of 44 sq. ft. x $84/100 sq. ft. = $37. Home Painters Louisville CO

Turn the brush to paint the adjacent edge of the same inside corner and repeat the process. Reload the brush and remove excess paint from the bristles by laying on the paint close to, but not against, the edge you’re cutting in. Without reloading the brush, go back and paint close to the edge. Fan the bristles slightly and use a slow, steady stroke while concentrating on the line you’re painting. Complete the exterior house painting job by smoothing the paint in the center of the panel with long, sweeping strokes, keeping well away from the completed edge. House Painting Louisville Colorado
