Yellow is generally a happy color that increases confidence. Similar to gray, yellow can be very versatile. Pale yellows used in sunlit rooms with flowery decorations are very inviting, especially in the morning time. Darker yellows can add warmth to a room even in the winter time. Bright yellows help reduce the amount of illumination needed in a space and are ideal for any room in the house.
You may not have heard this since your days in elementary school, but bust out the color wheels here folks (just in case you misplaced yours, we provided one for you). It’s one of the easiest ways to pick out what colors go with each other. Complementary hues (ones that go well with one another) are opposite each other on the color wheel. This isn’t by accident. It’s one of nature’s subtle ways of telling us it’s still in charge.
Paint gets more expensive as you go from flat to gloss. The difference is usually around $1 per gallon per sheen upgrade. Flat is the cheapest, then matte flat or eggshell, satin, semigloss then gloss. Paint also gets much more expensive the darker it gets. A white or neutral paint color can be as much as $20 less expensive than a deep base red or blue.
Considering the size of these rooms, one would assume that painting them is quite inexpensive.  Sometimes it is inexpensive but more often than not, it is not the case. The reason is mostly because of the more detailed work in tight spaces. Painting around bathtubs, light fixtures and cabinets takes a lot of time and careful brushwork. Getting up close and personal with a stranger’s toilet and painting behind it takes a certain “je ne sais quoi”. In a laundry room the difficulty depends on how the washer and dryer are installed and if the painter needs to move them to access the walls behind them.
To begin, move everything out of the room. Every painter we spoke with had a horror story about the time he didn't follow Rule No. 1. Bigger pieces of furniture can sometimes be left covered in the center of larger rooms, but if you are repairing drywall, says Chris Span, of Span's Quality Painting in Mobile, Alabama, "Take everything out. Drywall dust goes everywhere." Remove doors, light fixtures and hardware, and label everything with masking tape. Also, invest in drop cloths. "It's surprising how well a few drops of paint can cover a floor," says Rich Maceyunas, of Maceyunas Painting and Wallpaper in Waterbury, Connecticut. Buy high-quality drop cloths, such as canvas or paper-backed plastic. (Paint soaks right through lightweight fabrics and bedsheets.) Plastic sheeting works, but it's very slippery and doesn't absorb drips.
You may think you're home safe with a low- or zero-VOC paint, but once it's tinted with the universal colorants used in most paint stores, it could be anything but. On average, these colorants add about 150 grams of VOCs to a gallon; darker shades have more. To get around this, either settle for colors that are factory-mixed or look for paints with no-VOC tinting systems, such as Mythic, Freshaire Choice, or Yolo Colorhouse.
A good paintbrush is key to a professional-looking finish. "A quality brush costs $15 to $25, but you'll discover that pros aren't as talented as you thought," says Doherty. "The equipment has a lot to do with their success." Most of our pros prefer natural-bristle brushes for oil-based paints, but they recommend synthetics for all-around use. When choosing a brush, pay attention to the bristles. Synthetic brushes are made of nylon or polyester, or a combination of the two. Poly bristles are stiffer, which makes them good for exterior or textured work, but for fine interior work, Doherty uses softer nylon brushes. Look also for tapered bristles, which can help you work to an edge, and flagged tips, which help spread the finish smoothly and evenly. Brushes are available in 1- to 4-inch widths. Most painters keep an arsenal on hand to match the job. "Use common sense," says Maceyunas. "A smaller brush gives you more control, but no one wants to paint a door with a 1-inch-wide brush." Doherty recommends starting with a 2- or 2-1/2-inch sash brush. The angled brush makes it easier to cut to a line and puts more bristles on the work than a square-tipped brush.
The graph says the average cost to paint a home interior is $1600; at the high end, $4,000. But for what size home? I'm getting estimates for painting an 1800 square foot townhome in the range of about $6500 - which includes sanding and repainting all doors, and painting all trim, walls and ceilings. What does the range above include and for how big of a home? Thanks.
