• Most stucco colors darken slightly over time because they contain natural all-mineral ingredients. Unlike painted surfaces that have only a thin layer of paint that can fade, chip and/or peel, stucco color is “integral.” This means stucco color extends through the entire stucco layer instead of only on the surface. Properly maintained exterior stucco can remain attractive for many years with only minimal changes. However, exposure to dust, dirt and air pollution over time can slightly change its color. An application of LaHabra, Expo or Omega Fog Coat is the best way to revitalize stucco. Fog Coat is made specifically for stucco; therefore, it does not peel, fade, or break down like paint. It is also economical to apply.
