  • Synthetic stuccos: they are products obtained by mixing different materials and chemical formulations that are sold already manufactured and their composition is based on a patented mixture, they were very popular in the United States since the 1950s.
  • Modern stuccos: as the plastic stucco contain synthetic acrylic resins in general, they serve as a final coating, replacing the paint, they are easier to apply than the traditional ones, they are ready to apply.
