Paint gets more expensive as you go from flat to gloss. The difference is usually around $1 per gallon per sheen upgrade. Flat is the cheapest, then matte flat or eggshell, satin, semigloss then gloss. Paint also gets much more expensive the darker it gets. A white or neutral paint color can be as much as $20 less expensive than a deep base red or blue.
Climate is another factor to consider. Sunlight, wind, rain and salty weather can all wear out exterior paint. Oil-based paint is durable against wind, rain and temperature changes, but sunlight tends to degrade it. Alkyd paint chalks and sheds very thin layers when it begins to wear. Latex paint is the more durable option for very sun-drenched and relatively dry climate areas. Latex paint with high vinyl content should be avoided, however. Acrylic resin is by far the more durable binder for outdoor latex paint.
The speed with which a painter can complete the job will determine its final cost, but time is difficult to estimate. Some painters have more experience and cover a wall faster, but some are more methodical and take more time. Most painters should be able to cover about 100 to 120 square feet of flat surface in an hour, unless they are working on a very large wall. Wood or plaster might reduce that amount to 80 to 100 square feet. You should also consider the time required for a first coat to dry before a second coat may be applied. This will add time as well -- anywhere from one to 48 hours depending on the paint.

Even if you think you'll probably do the job yourself, it's good preparation to seek estimates from professional home painters, whether your painting the exterior or interior of your home. Then you'll have a financial point of comparison and you may benefit from what a home painting contractor has to say about the condition of your home, color choices and types of paint available. Let the painter make his pitch for a professional job before you decide what to do. You can still opt to do it yourself while having learned something worthwhile.

The only time it's acceptable to mix water in the paint is when you're using a deep or ultra deep base paint to reduce its stickiness, which is rare with new paint technology. Dark primary colors are composed almost entirely of tint that makes it very hard to work with without adding water. (You never use a sprayer and need to thin paint.?) If i was still in the industry I'd take the time to make a better article than this. Take this for a grain of slat. Use a reputable painter or someone you know you can trust or has been referred to you by someone you trust. I wouldn't hire anyone I had to watch like a hawk to make sure they're not screwing me.
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.
Did you even read the article? It was specifying UNSCRUPULOUS painters! And, by the way, the photo at the top was not identified at all. How would anyone know whether it was done by a homeowner or not? Also did you ever stop to think that if a consumer has the knowlege to spot a dishonest contractor then by default he also has the knowlege to identify an honest one as well? And, pardon me, but just because you've never seen something has absolutely nothing to do with whether it has actually happened to someone else. Why would any honest business person be so defensive about the publishing of such useful information? If any painters/painting contractors object to a consumer having this kind of information maybe they are the dishonest ones!
According to the Bureau of Labor Statistics, 45 percent of all painters are self-employed, though that number may be slightly higher if companies hire freelancers or self-employed painters as part of their team. The price that painters charge for their services is largely dependent on their association and whether the job is completed in the warmer or colder months (painters often charge more in the summer and less in the winter, given demand and other factors). More information regarding painter rates and associated factors is included below.

The Lead Renovation, Repair and Painting (RRP) Rule establishes requirements for firms and individuals performing renovations, and affects contractors, property managers, and others who disturb painted surfaces.  It applies to work in houses, apartments, and child-occupied facilities (such as schools and day-care centers) built before 1978.  It includes pre-renovation education requirements as well as training, firm certification, and work practice requirements.
