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 a specialized surface, and your preparation of the surface, as well as your coating choice are extremely critical to the success, and long-term durability of your project. Most standard paints and primers are inadequate to seal the pores of a stucco surface, even with multiple coats. You wouldn't want to use latex paint as a primer. Most latex paint in addition to not tolerating the high pH of stucco, often exhibits pinholes in the coating surface due to the porosity of the stucco.
