Gypsum lath is similar to a drywall panel, but smaller. Metal lath is used where the plaster application will be exposed to weather or water, or for curved or irregular surfaces for which drywall is not a practical material. Lathers usually nail, screw, staple, or wire-tie the lath directly to the structural framework. As in other construction trades, drywall and lathing work sometimes is strenuous. Applicators, tapers, finishers, and lathers spend most of the day on their feet, either standing, bending, or kneeling.
Some finishers use stilts to tape and finish ceiling and angle joints.
Installers have to lift and maneuver heavy panels. Hazards include falls from ladders and scaffolds, and injuries from power tools. Because sanding joint compound to a smooth finish creates a great deal of dust, some finishers wear masks for protection. Employment Drywall workers and lathers held about 133,000 jobs in 1994. Nearly one-third were self employed independent contractors.
