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.
Let the moisture soak in for 10 minutes and then spray the surface again. Do this until the stucco begins to feel loose or pliable to the touch. Do not use a pressure washer to soak the wall. A pressure washer will put out too much water and pressure and potential damage the supporting wall behind the stucco.
