What are hard coat stucco systems?

These are terms associated with the one-coat and three-coat systems described above. They are described as hard coat systems because the base coats used for these wall assemblies are formulated with portland cement/lime or masonry cement as the ‘backbone’ of the product.

EIFS as described above are synthetic systems – highly modified portland cement/fine sand, if used at all – is a very small component of the materials used to construct the wall. EIFS wall assemblies depend on additional components such as fiberglass mesh reinforcement to add durability to wall surfaces.

Water barrier and water management are also terms associated with stucco systems.
