What is a one-coat or a two-coat stucco system?
In the early 1970’s one-coat systems contained fibers and colored pigments in a single coat – it was a true one-coat application. The color tended to be washed out and inaccurate because the use of field mixed sands and the fibers would show in some areas as well.
By the 1980’s a topcoat of colored stucco finish was being used over one-coat stucco and the appearance of the finished product was greatly enhanced. Many people started calling that system “two-coat” but today just as many people still use the term “one-coat” to describe the two-coat system.
