Plan the budget. Costs will vary greatly, depending on price and quality. Choosing mid to upper-grade paint, expect to pay in the area of $350.00 in paint alone for a 2000 sq. ft. house. Add another $100 to $200 in brushes, rollers, pans, tape, and other materials. Don't forget food, if you plan to feed your workforce. When it comes to materials, not all paints are equal. Some truly cover with one coat, some say they do but don't. Your costs will double if you have to apply two coats to everything, so buying the cheaper paint might cost more in the long run. Trust your paint professional salesman (to a certain degree) to tell you which paint to buy. You can generally go cheap on primer, expensive on top coats.
As a former professional painter, something that drives me crazy is when I see painters cut in around wall plates. First of all, the amount of time that it takes to cut in is usually much longer than the amount of time that it takes to simply remove the wall plate. Secondly it does not look nearly as clean as it does when the wall plate is removed and thirdly it can invariably leave paint on the wall plate itself which also looks sloppy. Make sure the painter takes them off and then reinstalls them. It's less time.
Ideally, you want as much paint on the brush as you can control without making drips or blobs. To do this, Doherty dips his brush about 1 1/2 inches into the paint, then taps (not wipes) each side of the brush against the side of the can. Tapping knocks off the drips and forces the paint into the bristles. "The brush releases the paint just like a fountain pen," he says. Weeks agrees, saying, "Just be sure to keep your brush moving, or it'll start to drip." For more delicate work, such as when you're painting trim or window sash, you'll want less paint on the brush. Doherty again dips and taps his brush, but this time he also scrapes the sides against his can. "The outside bristles are drier and easier to manage," he says, "but there's still plenty of paint on the brush."
Some contractors work on time and material others on a firm contract. I would never hire the former and am leary of the latter. A contractor may low-ball a bid to get the job planning to make a killing on change orders. If you say good morning to them, they charge you extra for that. If the contract is not very, very specific and extensively fleshed out or if they display their change order schedule prominently on top, show them the door.
A good paintbrush is key to a professional-looking finish. "A quality brush costs $15 to $25, but you'll discover that pros aren't as talented as you thought," says Doherty. "The equipment has a lot to do with their success." Most of our pros prefer natural-bristle brushes for oil-based paints, but they recommend synthetics for all-around use. When choosing a brush, pay attention to the bristles. Synthetic brushes are made of nylon or polyester, or a combination of the two. Poly bristles are stiffer, which makes them good for exterior or textured work, but for fine interior work, Doherty uses softer nylon brushes. Look also for tapered bristles, which can help you work to an edge, and flagged tips, which help spread the finish smoothly and evenly. Brushes are available in 1- to 4-inch widths. Most painters keep an arsenal on hand to match the job. "Use common sense," says Maceyunas. "A smaller brush gives you more control, but no one wants to paint a door with a 1-inch-wide brush." Doherty recommends starting with a 2- or 2-1/2-inch sash brush. The angled brush makes it easier to cut to a line and puts more bristles on the work than a square-tipped brush.
