Once you have removed all the loose paint, you should apply an appropriate primer to some of the distressed areas, especially if your paint-removal system has exposed raw wood or bare metal. The kind of primer you use depends on the kind of paint you'll be using later. For latex paint, use latex primers; for solvent-thinned paints, use solvent-base primers; and for metals, use metal primers. Not only do these coatings provide extra protection against the elements, they also form a firm foundation for finishing paints. Also, priming is always required when you're working on new wood.
Paint will be your next-biggest cost, at anywhere from $20 to $70 or more per gallon, depending on the sheen, the grade you’ve chosen and any special features. Some paints, for instance, are mold resistant. Others suppress smells or require fewer coats. Some have a lifetime warranty. Paints with warranties, however, may not be worth a higher price. In Consumer Reports tests approximating nine years of wear, only a few exterior paints and stains with lifetime warranties held up well. But “you’ll grow tired of the color long before a good-quality paint wears out,” Bancroft says.
Painters will need several supplies for your home exterior project in addition to paint. Consider personally providing any materials that can be obtained without a license to reduce project costs. Painting supplies are also handy to have around for maintenance and touch-up jobs after the job is complete. The cost to invest in painting supplies will probably run you no more than $200 to $300, unless you buy really high-quality products from specialized paint shops. Consider purchasing the following:
“We hired Webfoot to paint our house in the Summer of 2009. He gave us a competitive bid, work started on the day he scheduled and concluded as per schedule. The workers and Gavin were very reliable, cleaned up their work space at the end of each day and were very trustworthy. The final project was exactly what the bid was and we wouldn't hesitate to call Webfoot for future projects. ”
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.
According to the EPA, professional painters must check for lead -- especially if a home was built before 1978. Many DIY painters forget to test for lead paint. Testing kits are available in home improvement stores for less than $40. You can also hire a lead testing and removal professional to do this work quickly and efficiently on your behalf. Lead paint can be dangerous; it's far better to find it before you put time and effort into painting your home than after the fact.
Historically, the painter was responsible for the mixing of the paint; keeping a ready supply of pigments, oils, thinners and driers. The painter would use his experience to determine a suitable mixture depending on the nature of the job. In modern times, the painter is primarily responsible for preparation of the surface to be painted, such as patching holes in drywall, using masking tape and other protection on surfaces not to be painted, applying the paint and then cleaning up.
The cost to paint the exterior of your home will vary depending on the size of your home, the condition of your siding, type of paint used and other factors. The average cost for labor and supplies ranges between $1,800-$3,800 and it may cost $6,500 or more for a large, custom project. In addition, you may need to pay more if there is damage to your siding or other challenging aspects of your job.
