Using an airless sprayer to place paint on the wall (using low pressure) will speed up the process because your not having to dip your brush or roller. spray about 3 or 4 sq. ft. and then back brush or roll spreading and evening the paint. Because your using low pressure, mask and cover is at a minimum once you are accustomed to handling the spray gun and the type of surface being painted. Overspray will be larger droplets they tend to fall, than float around.
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:
Once work begins, hold brief daily meetings to discuss the job and schedule and quash any misunderstandings. If there are surprises, seek middle ground. No contract can anticipate every possibility. Materials may be unavailable. Large chunks of rotten siding may crumble along with the old paint. Exterior jobs may be stopped cold by a week of steady rain. But know that you'll pay extra if you change your mind about a color after the trim is already painted or otherwise add tasks to the project.
O'Neil patches shallow holes and divots with Ready Patch because it dries fast, sands smooth, and stays flexible. Deep cracks and rotten spots are best repaired with two-step epoxies, such as those made by Advanced Repair Technology. (For a step-by-step instructions, see Repairing Rot with Epoxy.) The days of using polyester auto-body fillers on wood are over. "They cure too hard," says Portland, Oregon–based painting contractor Kathleen George. "They look good at first, but then they peel away."
To maintain a wet edge, start near a corner and run the roller up and down the full height of the wall, moving over slightly with each stroke. Move backward where necessary to even out thick spots or runs. Don’t let the roller become nearly dry; reload it often so that it’s always at least half loaded. Keep the open side of the roller frame facing the area that’s already painted. That puts less pressure on the open side of the roller, so you’re less likely to leave paint ridges
For interior jobs, make sure you've cleaned all of the awkward spots, including behind the toilet, and picked up any knickknacks that might get in the way (e.g., soap containers, loofahs, and kitchen organizers). Removing the switch plates and outlet covers from the walls also goes a long way toward speeding up painting time—and painters' time is (your) money.
The perfect roller would hold a roomful of paint, leave the right amount of texture, wouldn't spray or fuzz, and would be easy to clean. Until somebody invents the ideal one, follow these tips to choose the right roller. "The longer the nap, the more paint the roller will hold, but it will also create more texture." says Dixon. "A 1/2-inch nap lamb's-wool roller holds plenty of paint without too much texture," says Dixon. "Less expensive rollers can work," says Span. "Just wash them first in dishwashing liquid to remove any stray fibers." Most of the pros we spoke with prefer 9-inch rollers over 18-inch models -- they are lighter, cheaper, and easier to use. Despite these shortcomings, Maceyunas swears by the wider roller. "The roller can do a whole wall in a few up and down strokes instead of in several dozen W and M strokes," he says.
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.
