Many new homeowners want to change the color scheme of their rooms, either as a way to personalize the space or match the walls with existing furnishings and artwork. Interior house paint is relatively inexpensive, and it doesn’t require complicated machinery or professional-level skills to apply. There are also thousands of customizable colors available, as well as a choice of finishes, such as matte, semigloss, or gloss.
Determine the coverage area for each color and estimate the number of gallons you'll need for each. For odd walls with angled ceilings, make your best guess. If you're not comfortable doing this, measure the wall at its highest height and multiply that by its width. Now subtract the lowest height from the highest height, multiply that number by the width, cut that answer in half, and finally subtract that new number from the original height by width. That should give you the wall area.
The Ceiling. For ceilings, flat is recommended, except semigloss or satin should be used in bathrooms with showers/tubs. Some customers opt to go with a different finish for ceilings in general, to create a specific design look, i.e. high gloss ceilings on dining room tray ceiling to make a statement, or eggshell ceilings throughout to look modern and make a statement. 
Oil-based paint is commonly used for high-moisture areas, such as bathrooms and kitchens, and floors, trims, and moldings, since these areas take more abuse over time than walls do. Typically oil-based paints are less expensive than latex paints, take longer to dry, can create bad odor while drying, and contain more volatile organic compounds (VOCs), which essentially means they're less environmentally friendly.

On average, expect to pay $0.60–$1.60 per square foot for exterior painting. The average for painting labor across the country is $30–$40 per hour before you pay for paint, painting supplies, location costs, and equipment. To get a very general estimate, though, painting contractors will take into account the square footage of your home and the number of stories and also factor in normal prep work.
Choose the best quality paint you can afford; it lasts longer. Experts estimate that the outside of a house should be painted every 5-7 years, but less-expensive paint may start peeling or fading in 4 years or less while really high-quality paint will hold up a bit longer. Better Homes & Gardens[1] describes and compares the different types of exterior paint while FastFacts.com[2] reviews specific brands.
Some basic interior paints are sold in bulk, often in neutral colors such as white or beige. These can be very economical if the home’s color scheme is not a major consideration. However, many homeowners prefer to apply customized colors to match the furnishings or create a specific ambience for each room. Because of advancements in the industry, many manufacturers now offer a dizzying array of colors, from cool pastels to bold metallics.
Whether you decide to do the preparation work yourself or have a professional do it as part of your project, proper preparation makes all the difference in creating a smooth and lasting finish. Do it correctly the first time or you’ll quickly end up spending more to fix peeling and chipping paint. Follow this process before starting on your home's exterior. Keep in mind that the process may vary based on your siding materials:
Prime. Dark colors, stains (once sealed), and previously unpainted surfaces (drywall, spackle, etc.) will need a primer coat, usually white. NOTE: most paint stores & home improvement centers will now tint primer (at no charge) to match fairly close to the color of the finished coat, that way two coats of primer need not be applied.[6] Although not all surfaces need a prime coat, skip this step at your peril! Dark colors will likely show through the first -- or even the first couple-- topcoats of paint. Sealants and unpainted surfaces like spackle patches will absorb or repel moisture in a topcoat at a different level than the areas surrounding them. Applying a good primer coat will help even out these differences. Primer equalizes a wall to a uniform surface. It's like erasing a canvas before drawing a new picture. Although some will argue the point, you generally don't need to spend a great deal on primer or buy special primer. A cheap, 5 gallon (18.9 L) bucket of plain, flat white paint will usually do the trick and cover a large area. Give your primer at least 24 hours to dry (follow its instructions) before applying a topcoat.

The Cutters. Someone with meticulous attention to detail and a steady hand should be assigned the job of "cutting in," or painting a straight edge where needed, such as along a wall where the ceiling does not get painted. Many products are available to assist, but none work as well as a person who's good at doing it freehand. Ensure this person is skilled (ask them to show you). A poor, jagged, wavy or splotched cutting-in job will jump out at you every time you walk by it. Why more than one cutter? This job is nerve-wracking and painful to hands and arms after a few days. You'll want to give this person a break after a few walls.
Use semi gloss for hallways because walls there are more likely to be touched, bumped or otherwise marked over time (semi gloss cleans more easily). However, use flat for a living room. Flat will help hide imperfections in the walls. If you want the same color in both the hall and living room, then no problem. Use flat in the living room, semi gloss in the hall, making the threshold the transition point.
Decorating a house is a fun but important activity. It is important to make sure the curtains match the walls and the walls match the furniture. Earlier, all interior walls were painted in the same color, and in the same way. Today however, we get to have more fun with colors and textures. It's possible to create a fun effect on your walls using a sponge or even crushed tissue. You may want to paint one wall a different color from the rest of the room. You get to decide what colors you want to use, and how you want them to look on your wall. If you really want to decorate your entire home by yourself, you can even try painting your house by yourself with these 5 easy steps.
I hired a painting company to paint my house and garage. Price was about $5,000.Sherwin Williams paint T-1000. When he was questioned about the paint peeling two days after he painted the garage he quit even with a contract not a very professional person. So,now I have to find someone else to paint my house.After 3 weeks of them trying to paint around the rain. The original time frame was 3-4 days.Yes 3 weeks and all that got done was a small two car garage that could have been done in two days.I know he did not prep correctly and properly I will end up having to redo the garage. I went to Sherwin Williams and got the colors.So beware even with a contract and good references.
For trim and doors, start with 1 gallon (3.8 L) of trim paint for every 600 sq feet of floor space. Purchase more at the store if/when needed. Trim is something that is difficult to calculate exactly, and it is more time-efficient to simply start with less than you need, and go buy more after you have used up the first round of paint and determined how much you will need to finish by seeing how much you have painted so far, compared to the gallons used.
Give your fireplace mantle an accent paint color, as this adds a quick update without having to tear anything out. In the kitchen, give your cabinets a new look with a douse of kitchen cabinet paint for an affordable and satisfying update. Countertop paint makes kitchen countertops look new again. You can do it yourself with a countertop paint kit in less than a weekend. A worn-out bathtub can look new with a coating of bathtub paint. Even your tiles can get a refresh or touch up, try tile paint on your backsplash or shower. Pro-tip: Use semi-gloss paint for kitchens and bathrooms as they wipe down easily.
You’ll spend between $500 and $3,000 or $1 to $3.50 per square foot to paint concrete. However, expect to pay $2 to $7 per square foot since concrete almost always needs a coat of primer first. Double that price if the concrete requires stripping. Concrete is porous. Sealing it not only helps blend foundations and walls with your home’s aesthetic, but also seals it against water. Repairing or resurfacing concrete costs $300 to $500 for every 100 square feet.
