If your home was built before 1978, there is a good chance that lead paint was used in its construction. Scraping, sanding, or removing old paint can release toxic lead dust which can cause serious illness in children and pregnant women. Special handling is required when working with lead-based paints. If lead paint is present in your home, you will need to hire a lead-certified painting contractor or lead abatement contractor. Before getting started with your exterior painting project, consult your local building authority or visit www.epa.gov for more information.
The cost to paint metal siding -- most commonly aluminum and galvanized steel -- will depend on a variety of factors. In some instances, a simple cleaning will suffice to prepare metal siding for painting. In worst cases, painting professionals will need to repair metal that is rusted, damaged or missing pieces due to climate conditions. In the case of severe damage, a professional will have to remove the old finish and paint to get to the original layer, which will add on to the final price. When you add the actual painting of the metal siding, you might be looking at a final bill between $400 (~250 sq. ft.) and $1,500 (~1,000 sq. ft.).
As you scrape, you may find that the wood has turned gray or black in some areas. Check for rot by probing these areas with a nail. Spots that are discolored but firm are simply weathered. Weathered wood doesn’t hold paint very well, so sand away the gray surface. If you find soft areas, you’ve got rot. Small, shallow soft spots can be dug out and repaired with a two-part filler such as Minwax High Performance Wood Filler. But when rot is deep and widespread, it’s best to replace the entire piece of wood.
Every painting job develops a unique choreography as ladders go up and come down and tarps are unrolled and folded up. But two basic principles remain: 1) Start at the top and work down. 2) Work in the shade, out of the sun's glare. As the dance proceeds, keep an eye on the weather. Rain can wash freshly applied latex right off the wall, and a temperature dip below 50 degrees F two days after application can interfere with adhesion and curing and dull the sheen of glossy paints. (Latexes like Sherwin-Williams's Duration and Benjamin Moore's MoorGard Low Lustre are formulated to tolerate temps as low as 35 and 40 degrees, respectively.)
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.
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.
All colors have a base tone which might not be as apparent on a small swatch, but when the color is painted over an entire wall or room – the base color will stand out. Brown colors will sometimes appear to have a pink hue to them, and greys very often have some purple or blue to them. To avoid being surprised by a base color, take some time to look at the color fan deck for the selected paint color to see where the color comes from.
