Deciding which paint to use has gotten much easier now that acrylic latexes have pushed oil-based paints almost to extinction. The acrylics offer superior performance (they don't harden with age, the way oils do, so they move and breathe without blistering), they don't mildew as readily, and they emit fewer VOCs, so they comply with new air-quality regulations. They also work over both oil- and water-based primers.
When the primer is dry, caulk all small joints (less than ¼-inch-wide) in the siding and trim. Most pros use siliconized acrylics—paint won't stick to straight silicones—but Guertin and O'Neil like the new, more expensive urethane acrylics for their greater flexibility and longevity. O'Neil stresses that it's shortsighted to skimp on caulk. "If the joint fails, you're back to square one." Guertin uses the lifetime rating as his quality guide. "I don't expect 35-year caulk will last 35 years, but it should last longer than a 15-year caulk."
Repaint — exteriors especially — before visible signs of wear appear, Bancroft says. Don’t wait until you see peeling or flaking paint. “If I have to spend 40 hours preparing the surface before we can paint, that time is going to result in a lot of extra costs. But if I can spend 10 hours preparing the surfaces to be painted, you’re going to save money,” Freeman says.
Use a wire brush and a wide-blade putty knife to remove small areas of defective paint. Scrub under the laps of clapboard siding as well as on downspouts and gutters. For speedier work on metal, a wire brush attachment on an electric drill will remove rust and paint with less effort. For more extensive paint removal, invest in a sharp pull scraper -- a tool with a replaceable blade that's capable of stripping old paint all the way down to bare wood with a single scrape. Hold the scraper so the blade is perpendicular to the wood, apply moderate to firm pressure, and drag it along the surface. Keep the blade flat against the wood so it doesn't gouge the surface.
His team is very meticulous, very careful, very clean, and very courteous! They're also very accommodating. For instance, I mentioned a couple spots under some angled siding where I thought a little extra filling was needed, and they obliged without question. Same thing with a request for a stain-proof primer under a balcony. Doing these kinds of little things without question or extra charges is really nice!
A number of details will affect the cost of painting the exterior of your house, such as its size, accessibility and siding type. In many cases though, preparation often has the biggest impact on the bottom line.Your local exterior painting contractor will take a look at the project to determine how extensive repairs and preparation will be and if special equipment, materials or paints are needed to get the job done right.
A number of factors help determine when you should paint your home’s exterior. These include your local climate and weather conditions, the age of your home, and the type of siding used. A high-quality finish in ideal conditions could last 10 years. But if your home takes a beating from the elements, you may need to repaint as often as every three years. Most homes can be on a 5-8 year interval. If you’re not sure if your house is due for a refresher, watch out for signs of deteriorating paint, such as fading and chipping.
