Scope*1.1 This practice covers the minimum requirements andprocedures for field application of Direct-applied ExteriorFinish

    3、Systems (DEFS). Direct-applied exterior finish systemsare coating systems applied over various substrates withnon-metallic reinforcing mesh, in which the base coat rangesfrom not less than116 in. (1.6 mm) to332 in. (2.4 mm) in drythickness, depending on the mass of the reinforcing mesh. Thisbase coa
