ASTM C1516
Full Name
ASTM C1516 – Standard Practice for Application of Direct-Applied Exterior Finish Systems
Scope
This practice covers the minimum requirements and procedures for field application of Direct-applied Exterior Finish Systems (DEFS).
Direct-applied exterior finish systems are coating systems applied over various substrates with non-metallic reinforcing mesh, in which the base coat ranges from not less than 1/16 in. (1.6 mm) to 3/32 in. (2.4 mm) in dry thickness, depending on the mass of the reinforcing mesh.
This base coat is subsequently covered with a finish coat that is available in a variety of textures and colors.
