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.
Rapid Set Stucco Mix is a pre-mixed stucco material blended with Rapid Set Cement, high quality plaster sand, and high performance additives. Stucco Mix is used on exterior plastering applications where faster set times, higher strength, superior durability, minimal shrinkage, and reduced cracking are desired. Stucco Mix can be scratched, browned (or applied in one coat to 3/4 inch), and color coated in one day. Color can be applied in 3 hours. It is similar in appearance to Portland cement plaster and may be applied using similar methods. California residents: see Proposition 65 information.
