Three Coat Stucco Committee

About Us

The SMA Three Coat Stucco Committee is comprised of manufacturers and suppliers of three coat stucco products. Each committee has representatives who sit on SMA’s national board of directors.


Cement-based three coat stucco systems have been providing a long-lasting, attractive exterior cladding for buildings for over 100 years. Three coat stucco is recognized by IBC/IRC building codes and remains one of the most popular exterior cladding choices for residential, multi-family, and commercial projects. As its name suggests, three coat stucco is applied in three layers: 3/8-inch thick scratch coat, 3/8-inch brown coat, and 1/8-inch finish coat. Inherently fire, bug, and fungus resistant, three coat stucco is both durable and economical.
