Manufacturer: National Gypsum Company — Gold Bond Building Products division (Charlotte, North Carolina) Product Category: Acoustical Plaster / Ceiling Finishes


Product Description

National Gypsum Company marketed a broad line of building products — including plaster, joint compound, wallboard, and acoustical finishes — under the Gold Bond brand from the 1920s onward. Among the Gold Bond line was an acoustical plaster product designed to be trowel-applied or spray-applied to ceilings and upper wall surfaces in commercial, institutional, and monumental interiors where sound absorption combined with a monolithic (seamless) finish was specified.

Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Gold Bond acoustical plaster manufactured during the pre-regulatory era allegedly incorporated chrysotile asbestos into the gypsum-and-perlite plaster mix. According to allegations in publicly filed litigation records, chrysotile allegedly provided fiber reinforcement that held the porous surface texture required for sound absorption, improved fire resistance, and helped the plaster bond to lath or gypsum-board substrates. Gold Bond acoustical plaster was allegedly used in schools, hospitals, courthouses, theaters, transit-station ceilings, and other institutional interiors.

Documented asbestos-use period, according to publicly filed litigation records: approximately 1940s through 1978.

Trust status: National Gypsum Company established the NGC Bodily Injury Trust as part of its Chapter 11 reorganization to pay qualifying asbestos personal-injury and wrongful-death claims.


Workers Exposed

Plasterers were the primary trade allegedly exposed to Gold Bond acoustical plaster. Publicly filed litigation records allege that plasterers dumped dry-bag acoustical plaster into mixing hoppers and boxes, mixed the material with water to a workable consistency, and either trowel-applied or spray-applied the finish coat to overhead surfaces. Dry-bag mixing and spray application allegedly released dense clouds of respirable chrysotile fiber into the plasterer’s breathing zone.

Cement masons and interior finishers working on shared institutional job sites were allegedly bystander-exposed to airborne fiber generated during Gold Bond acoustical plaster mixing and spray application.

Drywall finishers working overhead on the same job sites — taping and finishing gypsum-board ceilings that received an acoustical-plaster finish coat — allegedly encountered residual airborne fiber and dust from cured plaster during sanding and touch-up operations.

Renovation workers decades later allegedly disturbed installed acoustical plaster during ceiling repairs, lighting replacements, and HVAC modifications. Publicly filed litigation records allege that scraping, patching, or sanding aged acoustical plaster released friable chrysotile from the cured matrix.

Demolition workers removing plastered ceilings during building demolition and renovation allegedly generated high concentrations of airborne fiber as aged acoustical plaster was chipped, broken, and swept into debris piles.
