Planning on whitewashing a charcoal gray wall? You’ll likely need additional paint when going from dark to light. On the other end of the spectrum, a deep color base tends to require more coats of paint than a lighter color, says Carolyn Noble, color marketing and design manager at Pratt & Lambert. She recommends applying a gray-tinted primer to the surface before you paint your walls a saturated color to help reduce the number of applications. When it comes to finish, you may have heard that the glossier it is, the higher the coverage rate, but it’s not enough of a difference to change the number of gallons you need to buy, Minchew says.
If you’re painting a highly textured surface rather than a smooth one, buy a little extra, says Julianne Simcox, Pratt & Lambert associate brand manager. Cabinets with complicated millwork require more paint, too; Minchew suggests purchasing about 10% more than calculated.
Calculate the correct amount of paint you’ll need to spare yourself trips back to the store and wasted paint.
5. Prep the walls and the room
You don’t want to damage your favorite sofa or that heirloom Grandma gave you, so empty the room of all the furniture. If you don’t have enough space to relocate everything you own, push it all to the center of the room. Cover the pieces with a drop cloth or lightweight plastic sheeting and do the same with the floor, as well as any cabinetry or countertops that might be in danger of excess splatter. “Don’t skip the drop cloth—paint will splatter, we promise,” say New Jersey contractors—and cousins—John Colaneri and Anthony Carrino, the stars of the HGTV series Cousins Undercover and Kitchen Cousins as well as The Build Upand Grand Design on Ellen DeGeneres’s Ellentube.
Grab a roll of painter’s tape—the cousins recommend FrogTape—and firmly apply it to the edges of the room’s corners, base and crown moldings, and door and window casings, using a putty knife to seal if needed. “Getting a good seal so paint doesn’t get under the tape is everything, plus it will pull away clean after everything is dry,” Colaneri and Carrino say. If you dare (or have an artist’s steady hand), you can skip taping entirely. Remove light switch and outletcovers and apply painter’s tape to protect outlets and switches from paint drips. Before you get started, make sure you know how to repair drywall so you can clean up any nicks in the walls.
