How Often to Clean Stucco?
Stucco surfaces need to be cleaned regularly due to their texture, as their texture is more prone to dirt, mildew, and mold. An ideal time interval is to clean them 2-3 times every year. However, most homes prefer stucco pressure washing once every year to maintain their appearance and structural integrity. But if your home is in an area with high humidity and heavy rainfall, it’s best to get it cleaned after every six months to keep away the mildew and algae buildup.
How to Clean Stucco With Pressure Washing
Cleaning stucco with a pressure washer involves several steps to ensure efficiency and safety. Follow these steps for a thorough cleaning –
Inspect and Repair the Stucco Surface
The first step in how to clean stucco is to inspect the stucco surface for any signs of damage. Check if there are any gaps, cracks, or any other openings. This is important because if the water gets into these cracks, it can result in mold and mildew formation inside the walls. You can repair the small chips and cracks by using the exterior acrylic caulking, as it seals the porous interior against water. But you need professional stucco pressure washing services for large cracks and crevices.
Prepare a Cleaning Solution
Several stucco cleaning solutions are effective in removing dirt and grime from them. How do you decide on the best cleaning stucco solution? Well, you can invest in a concentrated exterior cleaner specifically made for cleaning the outside of the home. Such cleaning solutions properly clean and disinfect. Don’t forget to follow the manufacturer’s guidelines to properly mix the concentrated exterior cleaner for the best results.
Spray the Stucco
Set up your pressure washer with a low-pressure nozzle, preferably between 1,500 and 2,500 PSI, so that it is completely saturated. This step in how to clean stucco is followed just to wet the wall. So, there is no need to set it under excess pressure. Keep the pressure washer angled at 45 degrees. Start from the top and then move downward to prevent streaks.
Apply Cleaning Solution
Can you pressure wash the stucco? Yes, you can. A stucco cleaning solution is generally made with a combination of liquid dish soap and water, and if the stains are in the form of mildew growth or mold, you can use something stronger, like water and bleach or a concentrated stucco cleaner. Put the stucco-cleaning solution in the spray and allow it to settle for 10-15 minutes. Now, start with one section of the wall and spray the solution on it. Spread it evenly to the entire area and give it time to break down grime and stains.
Scrub Difficult Stains
Some stains are so stubborn that you can’t get rid of them by simply removing them with a cleaning solution and rinsing them with a power washer. What you can do here is to use a soft bristle brush, dip it into the cleaning solution, and softly scrub the surface with it, as doing it too hard can smoothen the stucco surface. Or the best alternative is to always rely on experts in such situations who will help you pressure wash stucco surfaces, save your time and money, and make the whole process less taxing.
Rinse the Stucco Surface
You have applied the cleaning solution. Now it is time to rinse the stucco surface. Generally, a stucco surface takes 24 hours to properly dry after you have washed it. So, choose a day with no rain or wind in order to keep the stucco as clean as possible whenever it dries. Coming back, switch back to the low-pressure nozzle and rinse the stucco thoroughly, removing all cleaning solution residue. Ensure all areas, including corners and crevices, are properly rinsed to prevent detergent buildup, which can attract more dirt.
Pressure Washing Stucco Requires Proper Water Pressure
How to pressure wash stucco? The most important thing in this process is to use the correct pressure washer while doing stucco pressure washing. Use the right nozzle and keep it at least 18-24 inches away from the stucco surface to avoid any kind of damage. Start with the lowest pressure setting and test on a small, inconspicuous area before cleaning the entire surface. Improper pressure settings can lead to costly repairs, so always err on the side of caution.
