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.
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.
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.
Use a roller to paint the rest of the wall. A good method to use is the 'W method'. You start by painting a large 3 foot (0.91 m) square W on the wall. Then, without lifting the roller, you fill in the W. You can paint a wall section-by-section, and do the walls one at a time for best results. It's generally a good idea to use an extension pole for your roller instead of standing on a ladder. Make sure that neither the extension pole nor the roller has plastic handles, as plastic handles are flexible and this makes it difficult to control the painting.
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.
Supplies and Equipment – Scraping, sanding, and stripping tools and supplies; patching compound; power washer rental; primer; caulk; masking supplies; painters’ tape; ladders and scaffolding; paint pans; brushes, sprayers, and roller brushes all cost money, even if you do it yourself. Consider all of those tools and equipment sitting in your garage for the rest of your life vs. paying an experienced painter to do it all for you at a price that saves you weeks of time. Expect to pay $5–$6 per 100 sq. ft. for supplies and materials.
From dull to shiny finishes, paint comes in several different lusters. A paint’s luster depends on its mixture of pigment, resin, and additional ingredients. If you’re struggling to decide what finish you want, note that glossier finishes tend to be more durable and washable. Flat paint, on the other hand, is better at hiding surface imperfections. Pearl and eggshell lusters fall somewhere in the middle, as they are more washable than flat paint and partially hide irregularities.
Most of a projects price is the cost of labor at $25 to $75 per hour. However, most contractors bid out based on the entire project which includes all work hours. Hourly rates are only useful if your pro asks to do the job as “time and materials.” However, be wary of this pricing structure, it usually shows the contractor is uncertain how long the project will take.
