How to Paint a Stucco Concrete Block House

Pressure-wash the stucco to remove dirt. Set the pressure-washer to the lowest setting (between 1,200 and 1,500 pounds per square inch.) Use a wide-spray tip, as the water can strip away the stucco if it's applied with too much force.

Inspect the stucco for signs of damage. Repair small cracks by applying two coats of brush grade elastomeric sealant. Allow each coat to dry completely, which is typically four to six hours. Scrape away any loose stucco, and fill the space with a stucco patching compound.

Place blue painter's tape around the edges of the window frames.

Cover the stucco with an acrylic masonry primer. Begin by applying the primer to the stucco around the edges of the wall and around the windows with a paint brush. This is called "cutting in."

Cover the rest of the walls with the primer using a paint roller attached to an extension pole. Begin applying the primer in the top corner of the wall. Cover an area about three feet by three feet, working the roller in a motion similar in shape to the letter "M." Go over the same space again, this time making the letter "W" to cover the entire space with primer. Allow the primer to dry for the time specified on the packaging.

Apply the paint to the walls, first by cutting in with the paint brush and then with the roller. Allow the paint to dry. Add a second coat, or touch up with the paint brush if needed.
