Priming is compulsory if you're painting over a darker color, or on a new drywall, but it's a good idea to include this step before any paint job. A primer is necessary because it blocks any stains from bleeding through. It is also important because it prevents any blisters and paint-peeling by improving paint adhesion. Lastly, primer is a good idea as it allows complete single-coat coverage of the walls. If you want a better appearance, you can tint your primer with the final color you intend on using on the walls. Most paints today come with inbuilt primers, but an old school primer is still a better option. Before you start painting, remember to use painter's tape to cover your door frames, window sills, and any switches on the wall.
Plan the workforce. If you intend to not hire a professional crew, you'll need lots of help. There are many jobs to be done. First there's the furniture moving, then wall preparation, floor covering, materials gathering and prep, cleaning, and don't forget everyone will have to eat. It can easily take a team of five people a full ten days to paint a two-story (approx 2000 sq.ft.) home. Get as many people to help as you can. If some can only come one or two days, great. Maybe others can fill in. Ensure you plan with your workforce members in mind. They'll need plenty of time to arrange days away from work. Identify a few key personnel:
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.
The following guidelines will set you up for success. First, start at the top and work down. Second, paint out of the sun’s glare, since the sun will cause the paint to dry too quickly and flake or blister. To avoid marks, try to brush from one wet surface onto another. If you do have to paint onto a dry surface, overlap the wet paint onto the dry surface by several inches.
For walls, measure the linear feet of wall space (measuring along the baseboards) for the areas to be painted (using a tape measure, laser, or both). Then multiply this by the ceiling height (usually it is 7.5 or 8). If there are 2 story areas, measure them separately, and multiply them by double the regular wall height. Then multiply the total number by 2 (for 2 coats).
A single gallon of paint can run anywhere from $20 to $80 per gallon. Professionals get a contractor discount of anywhere from 25 to 50 percent. For rough siding, like stucco, you’ll need to use 10% to 20% more paint. Some textures, like wood and stucco, require extra paint because they have more surface to cover in a tiny area compared to smooth siding. Use the highest quality exterior paint your budget will allow for your project. It will look the nicest and save you money by offering better coverage and durability. Better coverage means fewer coats and fewer work hours. You’ll also go a few years longer without needing to shell out more cash for a new coat. How do you know how much paint you're paying for? Here's some helpful math:
