In past decades builders have used everything from animal horns to whiskey to create stucco—an attractive, durable plaster finish suitable for both interior walls and exterior siding. Today, the material typically consists of more familiar ingredients like cement and sand, but it remains as tough as ever, often lasting as long as 50 or 80 years. However, in order to live out its expected lifespan successfully, stucco tends to require a modest amount of care and attention. How much largely depends on the nature of the application.
Indoor stucco may call for nothing more than a new paint job now and again. But with exposure to the beating summer sun, the howling winds of winter, and simply the dirt and dust kicked up by passing traffic, it’s only a matter of time before stucco siding needs minor repair or, at the very least, a simple cleaning. For many homeowners, stucco maintenance starts and ends with a close look at the surface or surfaces in question. If your inspection reveals a reason to go a step further, read on for advice on ensuring your stucco looks and performs its best.
A porous material, stucco collects dirt and absorbs stains, even indoors. The good news is that cleaning indoor stucco usually takes nothing more than water and a bit of elbow grease. Simply scrub the dingy stucco with a dampened nylon brush to saturate the surface, then rub away the buildup with a moistened microfiber cloth (or clean cotton rag).
In extreme cases—for instance, with deeply set stains—you may find that you need more firepower. Experts recommend, not a conventional household cleaner, but a chemical solution known as trisodium phosphate, or TSP. Though it’s commonly available at home centers and hardware stores, be advised that in order to use TSP safely, homeowners must take the proper precautions. Ventilate the area by opening windows and running a fan, and when working, wear the right gear (rubber gloves, protective eyewear, and long-sleeve clothing). Once it’s safe to proceed, combine the TSP with water in a bucket, diluting to water-to-TSP ratio of 15 to 1. Finally, apply the TSP to the affected area by means of a nylon brush and allow the stucco an hour or two to dry.
In outdoor applications, when used as a siding material or even a garden wall finish, stucco tends to get a lot dirtier and for that reason, requires more frequent cleaning. The process doesn’t take long, though, so long as you use either a garden hose (equipped with a spray nozzle) or a power washer (on its lowest setting).
With your chosen tool set to spray in a mist formation, saturate the stucco from bottom to top.
Next, switch to a more concentrated spray and proceeded to clean, not from bottom to top, but from top to bottom (that way, dirt higher up on the wall doesn’t simply settle at the base).
After spraying, check the stucco for any lingering buildup and, if you encounter any buildup, dislodge it with a stiff-bristle brush. Just be careful not to scrub so vigorously that you grind down the stucco.
Now, if blemishes still remain on the siding, there’s one more step. With a pump sprayer or a hose wand with a built-in soap reservoir, apply diluted TSP (described above) directly to the affected areas.
Finally, having allowed sufficient time for the stucco to dry, finish up by rinsing the stucco surface one last time.
