Step 2 - Preparing the MaterialsĪ number of joint compounds can be used for skim coating. You should also properly clean and dry it. Just pressure-washing and adding only a color coat (with no base coat) would take about half the time as pressure-washing and adding both a base coat and a finish coat.Before doing the project, make sure that the paneling you will be working on is anchored firmly on the wall. The finish coat can’t be applied until the base coat is sufficiently cured. The total duration of any project will need to include time for the base coat to cure, which can be a week or more. The same work on a 3,000 square foot home would take anywhere from two to eight days of labor. Pressure-washing a 1,500-square-foot home and adding a base coat and a color coat could take one to four days of active work by professionals, not including cure time. If only a color coat is needed, the cost would be 20 to 30 percent less. The same work on a 3,000-square-foot, two-story home would run $9,000 to $15,000, he says. Stucco pro Ryan Clark of Blue Collar Stucco in Nevada City, California, says rates to pressure-wash a 1,500-square-foot home and retexture it with a base coat and finish coat would run $4,500 to $7,500 in his area. If only a color coat is needed, the prices would be about half that. For a 3,000-square-foot, two-story home that requires scaffolding, the cost could be $38,000 to $40,000. In the high-priced San Francisco Bay Area where Giordano lives, the cost to pressure-wash and retexture with a base coat and a color coat on a 1,500-square-foot house would typically run $12,000 to $14,000. The cost of applying a smooth stucco finish varies widely from region to region. A good stucco and plastering professional will be able to tell you which solution would be appropriate for your home.įind siding and exterior professionals near you As may be expected, adding just a color coat is typically less costly than adding both a base coat and a color coat. When the indentations in the existing stucco are very shallow (less than one-eighth inch deep), a color or finish coat will be all that’s needed. After the base coat, the professional will apply the finish, or color coat, which is typically about one-eighth of an inch thick. This base coat can vary in thickness from one-eighth of an inch to more than half an inch and is what will smooth out the undesirable texture. He or she may use a premixed adhesive stucco that will stick to the existing stucco, or the pro may apply a bonding agent to the existing stucco before applying a skim coat of a mix of cement and sand. After that, the pro will apply a new stucco base coat. The pro’s first step will be to power-wash the home. A stucco pro will simply apply a new texture over the existing one. In most cases there’s no need to remove the old stucco to create a smoother surface. But homeowners who find that their homes need to be power-washed frequently may want to consider a smoother stucco surface the next time they have exterior work done. Power-washing can clean off the dirt and grime and refresh the look of dingy stucco, and painting can also refresh its look. Smoothing a stucco surface can make it less welcoming to insects, Giordano says. Giordano has heard from multiple homeowners who find spiders making webs and living in the deep indentations in their stucco. Eventually, moss may grow in the indentations. “The more texture, the more dust it holds,” Giordano says. Dust and pollutants in the air also settle onto a home’s roof, and when rainstorms wash this grime down the front of the house it settles into the crevices of heavily textured stucco and can leave a streaked appearance. “The rain is full of dust,” Giordano says. Heavily textured stucco can collect dust in its indentations, which over time can lend a dingy appearance, says Kirk Giordano, a plastering and stucco contractor based in Alameda, California. There are also maintenance reasons a homeowner might want smooth stucco.
