You can use small bits that are up to 3/8 inch in diameter, or larger bits that are 1/2 inch or more in diameter. Make sure the bits you use are coated with carbide or diamond; this information is usually visible on the package. You can also use hole saw bits to drill into stucco.

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.

To repair damaged exterior stucco, you’ll first remove all loose and crumbling material from the damaged area. You then need to thoroughly clean the area and dampen it to ensure proper bonding. After that, you’ll apply a bonding agent to the repair area, then apply new stucco in layers, allowing for curing time between each layer. The final coat should be textured to match the surrounding stucco pattern as closely as possible. Once fully cured, the repaired area can be painted to match the rest of the wall if needed.

Stucco will dry in two to three days, but you should wait one to two months to allow it to cure fully before you paint it. The curing process is slow, but leaving the material exposed to air and natural moisture will help it reach its maximum strength. If you live in a hot, arid climate, wait a month before painting. Wait two months before painting if you live in a more moderate or wet climate.
