Question 5

What PSI should you use to clean stucco siding?

Accepted Answer

•

When cleaning stucco siding, it is recommended to use a pressure washer with a psi (pounds per square inch) between 1,500 and 2,000. This range provides sufficient power to remove dirt and grime without causing damage to the stucco surface. It's important to avoid using excessive psi as it can chip or crack the stucco.

Using a wider spray nozzle and keeping a safe distance of about seven to 10 feet from the siding helps ensure a gentle and effective cleaning process. Always follow the manufacturer's guidelines and adjust the psi accordingly based on the condition of your stucco and the specific requirements of your pressure washer.
