Cleaning eifs (synthetic stucco) safely
EIFS looks like stucco but is a foam insulation board with a thin acrylic finish coat. It dents and gouges easily, and water forced behind it is a well-known cause of hidden damage, so it is cleaned with low pressure and solution, never blasted.
Avoid: Any high pressure, which can tear the finish coat or drive water into the wall system.
How often: Every 1-2 years.
