Cracks and holes in stucco can result from several causes, including poorly applied or poor-quality stucco. Settling can also cause cracks if there isn’t good reinforcement where walls meet or other building elements intrude.
The keys to a successful repair job are giving the stucco enough time to cure and carefully matching the color and texture of the existing wall.
To match the color, add pigment to the topcoat of the stucco or repaint that part of the wall once the stucco has dried completely. You may need to add sand or small pebbles to the stucco to match it. Create texture with a trowel, float, or brush.
Stucco is porous, and moisture passes directly through. In warmer and drier climates, painting doesn’t affect this process as much as it does in colder climates. Check what local contractors advise before you paint your stucco wall. If paint is an option, choose a 100% acrylic latex paint specially formulated for stucco surfaces.
To give a stucco wall a fresh, new look, clean it with a garden hose and sprayer filled with a very dilute solution of TSP. Be sure to thoroughly rinse off the mixture.
