A gallon of paint costs $15 to $40 and covers about 350 square feet with one coat. Designer varieties can run over $100 per gallon. Your contractor pays 50 percent less than what it runs in a home improvement store. You’ll also need to spend another $20 to $100 on supplies like brushes, rollers, masking paper and plastic. A professional will have these items on-hand.

Stripping – $54–$151/100 sq. ft.. “The principle of paint strippers is penetration of the paint film by the molecules of the active ingredient, causing its swelling; this volume increase causes internal strains, which, together with the weakening of the layer's adhesion to the underlying surface, leads to separation of the layer of the paint from the substrate.”— Wikipedia. All the stripper will do is soften the paint. You’ll still have to scrub or scrape it off.
An example of the wall measurement would be: 40 linear feet of bedroom space, x 8 wall height, =  320, x 2 = 640. Minus 1 door (60) and 2 windows (80) = 500 sq feet being painted. Then divide the 500 by 400 (sq feet per gallon), and you get 1.25 gallons (4.73 L) needed for that room. For this, you'd need 1 gallon (3.8 L) and 1 US-quart (950 ml). If the amount it comes out to is over 1.3, we recommend just getting 2 gallons (7.6 L) so that you have leftovers if needed, since 2 US quarts (2,000 ml) costs essentially the same as a gallon in most stores.

A. Many homeowners purchase small sample cans of interior paint at a local home improvement store and apply each one to a different section of the wall. You should look at each color under different lighting conditions, such as natural daylight and nighttime lighting. You'll also want to consider the general color scheme of the furnishings, artwork and flooring that will be in that space.
While some professional painters will charge a flat fee for a painting project, most charge an hourly rate—about $25 to $100 per hour on average. Most painters will charge more for last-minute jobs (think 48 hours' notice or less), travel costs (if you live far away, the painter may want extra money for gas), or intensive prep work (e.g., removing mold or stains before painting). Also, depending on the painter, the rate may or may not include the cost of paint materials such as paint, primer, and supplies.
Repainting is key to maintaining exterior house paint. The material that your home is made of affects how often you should repaint. For instance, wood-paneled homes need to be repainted twice as often as those made of stucco. Environmental factors also play a role in how often you should repaint, since harsh climates can be hard on a home. As a general rule of thumb, homeowners should repaint their home every six to ten years.
Expect to pay between $600 to $3,500 or $1.25 to $3 per square foot to coat vinyl, with prices likely increasing for the finish. It is one of the more inexpensive siding materials to have repainted, especially with recent innovations in materials. Changing the finish on your siding is not recommended unless it's completely degraded and worn away by the weather. You can save nearly half the vinyl siding installation cost of $4 per square foot by painting rather than replacing. Before adding a new coat to vinyl siding,
