DISCUSSION—
As an alternative method, back wrapping is achieved by wrapping the edge, back, and exterior side of the insulation board with reinforced base coat
prior to fastening the insulation board to the substrate. This is referred to as prewrap.
base coat, n—the initial wet-state material, either factory or field-mixed, used to encapsulate the nonmetallic reinforcing mesh or
fasten the insulation to the substrate.
cold joint, n—the visible junction in a finish coat.
cure, v—to develop the ultimate properties of a wet-state material by a chemical process.
drainage mat, n—component used in some EIFS-clad drainage wall assemblies, a corrosion resistive material used as a spacer to
provide a drainage path between the EIFS and the weather resistive barrier.
dry, v—to develop the ultimate properties of a wet-state material solely by evaporation of volatile ingredients.
durability, n—the capability of a building assembly, component, product, or construction to maintain serviceability over not less
than a specified time.
edge wrap, n—the condition of the perimeter at the EIFS where the reinforced base coat is terminated by wrapping the reinforced
base coat onto the edge of the substrate. (See Fig. 12.)
