ASTM C1063-11a

Standard Specification for Installation of Lathing and Furring to Receive Interior and Exterior Portland Cement-Based Plaster

ABSTRACT
This specification covers the installation of lathing and furring to receive interior and exterior Portland cement-based plaster. The following materials shall be used: metal plaster bases—expanded metal lath and wire laths; accessories—steel, PVC plastic, zinc alloy, and cornerite; channels—external corner reinforcement and foundation weep screed; wire; rod and strap hangers; clips; fasteners—nails and screws. Hangers and cold-rolled channel main runner shall conform to the allowable spacing and spans, respectively. The following methods are discussed: installation of hangers for suspended ceilings under wood constructions, attachment of hangers to main runners, installation of main runners, installation of cross furring, metal furring for walls, lapping of metal plaster bases, spacing of attachments for metal plaster bases, application of metal plaster bases, and application of accessories.
SCOPE
1.1 This specification covers the minimum requirements for lathing and furring for the application of exterior and interior portland cement-based plaster as in Specification C926 or Specification C841.
1.2 Where a fire resistance rating is required for plastered assemblies and constructions, details of construction shall be in accordance with reports of fire tests of assemblies that have met the requirements of the fire rating imposed.  
1.3 Where a specific degree of sound control is required for plastered assemblies and constructions, details of construction shall be in accordance with official reports of tests conducted in recognized testing laboratories in accordance with the applicable requirements of Test Method E90.  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
