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 applied wet and hardens to a very dense solid. Mixed and installed incorrectly, it can very easily fail. Because it ultimately hardens and is so rigid, it is prone, like plaster, to settlement cracks. This article will focus on repairing issues that arise from this type of normal and expected wear and tear.
