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.
Stucco is one of the oldest forms of siding, and itâs one of the most effective options still available to this day. Of course, itâs a bit more modern today than it was all those years ago when it became part of Greek homes. Stucco is a mixture of Portland cement, sand, and water.
