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.
5 Repair Stucco: Mix. Mix the first coat of stucco, known as a scratch layer using a wheelbarrow. If the mix is too small, mix it on a small bucket: one part Portland cement, four parts builders' sand and a little bit of water. Cover the area to be patched with a bonding agent made for masonry.
