Revision of C1861-20 Standard Specification for Lathing and Furring Accessories, and Fasteners, for Interior and Exterior Portland Cement-Based Plaster


C1861 Corrosion Resistant Fasteners Rationale: Proposed revisions to clarify requirements of corrosion resistant fasteners, for the convenient reference of specifiers, manufacturers and lathers. 1.Lath fasteners in contact with pressure treated-wood framing or sheathing panels at building interior and exterior locations, are used in certain applications and climate regions under stucco claddings. Appropriate corrosion-resistant fasteners are required by the building code, but not currently clearly specified in C1861. 2.Lath fasteners in contact with lathing and lathing accessories of different metals must be materially compatible to avoid bimetallic corrosion.
