Most siding material needs at least some sort of scraping, sanding or stripping before repainting. Chipped or bubbled paint not firmly adhered to a surface creates a weak area that leaves fresh paint more vulnerable to damage. Scraping removes large loose pieces. Sanding then smooths the edges of whatever paint remains. Keep in mind the process varies based on the type of siding. House Painting Westminster CO

The last big decision is how to apply the paint. Most pros use paint sprayers because they're fast, but in inexperienced hands a high-powered sprayer can leave drips, thin coats, and a mist that may land on many things other than your siding. If you do hire a painter who uses a sprayer, make sure he is meticulous about removing, covering, or masking off everything in the area that might get hit with overspray: gutters, roofs, windows, shrubbery, walkways, cars—you name it.
Painters often tint primer close to the color of the top coat, but Wallis thinks that's a recipe for "holidays," or missed spots. Instead, he tints his primer a contrasting color. "If I can see the color coming through, I know I need to apply more paint," he says. On the cottage shown in this story, he chose a gray-blue primer to go under a peach top coat.
A thorough scrubbing is a must before painting any exterior surface. It removes the dirt and broken-down paint residues that keep fresh coats from adhering and gets rid of mildew that grows on paint in all but the most arid climates. Most contractors clean with pressure washers, but in the hands of someone unfamiliar with the equipment, these can gouge wood, shatter glass, and drive water behind siding and trim. Using a hose, a pump sprayer, and a scrub brush is slower but safer, and just as effective. House Painting Westminster CO
How much paint will you need? It takes about 8 gallons per coat to cover a 2500 square-foot house with wood or metal siding. Two coats are usually recommended, making the cost of paint $640 – $1440 depending on the per-gallon cost. Textured or porous siding, such as stucco or concrete, have a greater surface area and require up to twice as much paint for full coverage. House Painting Westminster
