It’ll cost you between $500 and $1,000 to paint the exterior yourself. Not including paint, it’ll cost you no more than $200 to $300 at a home improvement store like Home Depot, Lowes or Menards. You may end up spending more if you buy high-quality products from specialized shops. Professionals can get the same supplies for about half what you’ll pay.
Wood is probably the most time-consuming when it comes to preparing it for paint. It has to be scraped and sanded until there isn’t a single chip or bit of loose paint in sight. Any wood siding or trim with wood rot will need to be replaced, and all cracks and holes need to be filled with epoxy filler. Brush painting and roll painting wood siding costs $43 per 100 sq. ft., and spray painting costs $34 per 100 sq. ft. Home Painters Louisville CO
Stripping – $54–$151/100 sq. ft.. “The principle of paint strippers is penetration of the paint film by the molecules of the active ingredient, causing its swelling; this volume increase causes internal strains, which, together with the weakening of the layer's adhesion to the underlying surface, leads to separation of the layer of the paint from the substrate.”— Wikipedia. All the stripper will do is soften the paint. You’ll still have to scrub or scrape it off. House Painting Louisville Colorado
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. Louisville Home Painting
