Stucco is a durable and beautiful building material, but homeowners should accept that it just isnât waterproof. If youâre concerned about damage to your home, look from these signs that your stucco is, indeed, due for a waterproofing job: Paint coating stucco is chipping, peeling, fainting, or cracking.
Whisk the entire surface you plan on covering with new stucco with a broom to clear it of debris. If possible, such as with an outdoor setting, use a pressure washer with regular water to scour the surface clean. Do not apply direct streams of water on the surface or allow the water jets to peel back the stucco.
