Phraseology

Lathing – All Operations to Completion & Drivers

Description

Code 5443 applies to employers engaged in lathing work.  Lathing work is performed by specialist contractors that install metal, wood or gypsum lath in strips or other sheet forms to provide a support base for the application of plaster or stucco coatings.  This type of work may be done on interior or exterior building surfaces.  Lath is attached to studs and joists.  This classification also includes using control joints, corner beads and screeds to reinforce and provide structural support for the lath that is installed.  Control joints are metal strips put in place to relieve strain around large areas such as ceilings and walls.  Corner beads are set in place to provide reinforced corners and are usually installed over gypsum surfaces and screeds are used as separators, which separate plaster from concrete and other surfaces.

Once the lathing material is installed, the plastering contractor can apply the plaster or stucco finish.
