Durock Exterior Finishing Systems

Cement boards are typically tough and highly weatherproof materials. As such, Durock DEFS (Direct-applied Exterior Finish System) is acceptable as a substrate for a Direct-applied application of EIFS lamina. Direct-applied (DA) means that no rigid polystyrene foam is used.

Durock DEFS is intended for use on steel frame , wood frame, soffit and canopy assemblies. Durock DEFS may also be used over concrete. This Durock system has the advantage of directly receiving different colors and textures finished over a surface tuned with USG DUROCK® Brand Basecoat compound.
