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.

Prepping a house costs anywhere from $0.50 to $2.50 per square foot. This is almost always included in the total project price. However, the DIYer might negotiate some discounts for completing this work on their own. Be warned, proper prep is key to the quality and durability of the finish. If you do this work yourself, the contractor might no guarantee to finished product.
House painting is no easy feat. While you may be tempted to purchase the cheapest kind of paint you can find, remember that you want the paint to look good and last a long time. If you haven’t chosen a color palette, there are a number of apartment design apps out there to spark inspiration. Once you’ve decided upon your color scheme, you’ll have to choose what kind of paint you want.

Your contractor will sweep or scrub the concrete first with a dry brush, and then clean it thoroughly with trisodium phosphate (TSP) and warm water, then let it dry. TSP is a mostly alkaline solution that does a great job cleaning grease and oil off concrete surfaces. Brush painting concrete siding costs $138 per 100 sq. ft., roll painting costs $50 per 100 sq. ft., and spray painting $32 per 100 sq. ft.


While you may choose to paint a door, ground-level window trim and other parts of your house’s exterior, it’s really a job best left to the professionals. One of the main reasons is experience. An experienced painter knows how to handle the prep work, spot problems and identify sources of future trouble, all while getting the job done more efficiently. They are also experienced with spending long hours on tall ladders. If you want high-quality work, it’s best to hire a professional painter near you. 
In addition, paint features such as mold and mildew resistance are important cost factors. Many mold-inhibiting bathroom paints, for instance, cost substantially more than ordinary latex-acrylic paint—sometimes close to twice the cost. Also, paints that come with warranties from the manufacturer may be more expensive depending on the length of the warranty. (A two-year warranty is standard.)
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. 
Following the same process as the primer, cut in the walls with your chosen paint. For best results, paint one wall at a time. This makes it easier to spread the paint while it’s still wet. Work from top to bottom, rolling the paint in V or W-shaped strokes. Before applying a second coat, wait two to four hours. Then proceed with the same process used for the first coat.
Flat, or matte finish on the no-shine end of the finish spectrum. A friend to walls that have something to hide, flat or matte paint (the terms are interchangeable) soaks up — rather than reflects — light, has the most pigment, and provides the most coverage. It's good for adults' bedrooms and other interior rooms that won't be roughed up by kids. That's because it's tough to clean without taking paint off.
Even if you hire a professional, you may need to play a small role in your house painting process. This could be anything from moving your furniture to the center of the room to removing switch plates and outlet covers. Ask your painter how much prep work is expected of you before hiring. The amount of work you’re willing to do could help you narrow down the right painter for the job.
One of the most common home-improvement projects can also be one of the most enjoyable for the entire household. While some aspects of interior room painting, such as masking and “cutting in,” can require some experience and skill, applying a fresh coat of paint to a ceiling or wall or doorway is often a matter of a good brush, a paint tray, and some sweat equity. A coat of fresh paint may be all that’s required to revive a living space that’s faded a bit.
Priming - $30–$40/hour for labor. Many of the materials above need to be primed, but not all do. If you’re changing paint colors from dark to light or light to dark, use a color similar to the top coat. That way you’re less likely to need extra coats over the standard two. Prime with a flat or eggshell paint. You can ask your paint store to add tint to the primer to match it with the top coat color. Hammer in exposed nails and spray them with a metal primer to prevent rust.
My husband and I decided that we wanted to update our deck to have a modern cable railing...our house is very "treehouse" like, sitting high up in the words and the new cable railing really opens up the view. The guys striped the deck of its old paint and got started on taking down the old railings--they actually added an extra 6" around the perimeter of the deck to serve as a better support for the new posts that were put in and what a difference! Johnny and Robert, who worked together on the labor intensive deck, are truly artists.....cutting perfect curves into areas of the railing where we have a large boulder in our yard and using their creativity to further enforce our deck--talk about attention to detail! Its really hard to believe that we're living in the same house and thanks to Rome, there was never a time when I felt stressed or pressured to make a decision. I can't forget to mention that Rome is very reasonable when it came to giving us a quote for the entirety the work we had done, we were VERY pleasantly surprised!!

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.

Compare offers. The painter offering the lowest rate may not always be the best painter for the job. Indeed, the total cost isn't the only factor to consider when choosing between multiple bids. You'll want to look at contracts side by side to ensure you're making an apples-to-apples comparison. Are the same materials being used? Are the same services included? Does the painter provide a warranty?
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:
