Durabond Joint Compound – USG Corporation
Product Description
Durabond joint compound is a setting-type drywall compound manufactured by USG Corporation, one of the largest wallboard and finishing materials producers in the United States. Unlike conventional air-drying joint compounds, Durabond products are chemically setting compounds, meaning they harden through a chemical reaction rather than simple evaporation of water. This characteristic made Durabond popular across residential, commercial, and industrial construction for applications where fast set times and high strength were required.
USG Corporation, headquartered in Chicago, Illinois, has been a dominant force in the gypsum products industry for well over a century. The company marketed Durabond under its established brand umbrella alongside other well-known products including SHEETROCK wallboard, IMPERIAL plaster, and a range of ceiling tile systems. Durabond joint compound was sold in powdered form, requiring workers to mix it with water on site before application.
The product was widely used by drywall finishers, plasterers, construction laborers, and other tradespeople involved in the taping, bedding, and finishing of interior wall and ceiling systems. Its use extended into industrial facilities, institutional buildings, and large-scale commercial projects where the demands of fast-paced construction schedules made setting compounds the preferred choice over slow-drying alternatives.
Asbestos Content
During portions of Durabond’s production history, USG Corporation incorporated asbestos into the formulation of this joint compound. Asbestos was added to joint compounds and related finishing products for several functional reasons: it improved workability, reduced cracking during setting, provided a degree of fire resistance, and enhanced the overall strength of the finished surface. These same physical properties that made asbestos attractive to manufacturers also made it extraordinarily hazardous to the workers who mixed, applied, and sanded these products.
The United States Gypsum Asbestos Personal Injury Settlement Trust — established as part of USG Corporation’s bankruptcy reorganization — specifically recognizes asbestos-containing products manufactured and distributed by USG Corporation, including Durabond joint compound. The existence of this trust confirms that USG acknowledged the presence of asbestos in certain products and accepted legal and financial responsibility for resulting personal injury claims.
Regulatory action by the Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA) during the 1970s led to the reformulation or elimination of asbestos in many joint compound products across the industry. However, workers who used Durabond during the years when asbestos-containing formulations were sold — and those who disturbed previously applied materials during renovation or demolition work — faced serious exposure risks.
How Workers Were Exposed
Occupational exposure to asbestos from Durabond joint compound occurred through several well-documented pathways, all connected to the ordinary tasks required to use the product.
Mixing: Durabond is a powder-based compound. Workers who opened bags and poured powder into mixing containers generated clouds of airborne dust. When asbestos was present in the formulation, this dust contained respirable asbestos fibers that could be inhaled with each breath taken during the mixing process. Workers who mixed compound repeatedly throughout a workday faced cumulative exposure over the course of entire careers.
Application and Taping: Applying joint compound to drywall seams, corners, and fastener heads brought workers into direct contact with the material. While wet compound poses a lower immediate inhalation risk, overspray, splatter, and incidental drying of applied product during work could release fibers into the breathing zone.
Sanding and Finishing: Sanding dried joint compound to achieve a smooth, paintable surface is one of the most hazardous steps in the drywall finishing process. OSHA and industrial hygiene research have consistently identified sanding as a primary source of asbestos fiber release from joint compound products. Workers using hand sanders, pole sanders, or power-sanding equipment on dried Durabond — when that compound contained asbestos — were exposed to high concentrations of airborne fibers.
Renovation and Demolition: Workers who disturbed existing joint compound applications during building renovation, repair, or demolition faced secondary exposure long after the original installation. Cutting, scraping, or grinding previously applied compound that contained asbestos released fibers just as effectively as the original application work.
Industrial workers generally, including those employed in facilities where Durabond was used for interior finishing and maintenance applications, are recognized among the trades and occupational categories potentially exposed. Construction laborers and general workers present in enclosed spaces during mixing, application, or sanding operations — even if not the primary applicators — could experience bystander exposure through the shared air environment of a worksite.
Asbestos fibers inhaled or ingested do not break down in the body. Over time, accumulated fiber burden can cause mesothelioma, asbestosis, lung cancer, and other serious diseases. These conditions often do not manifest until decades after the initial exposure, meaning workers who used Durabond joint compound during the product’s asbestos-containing production years may only now be receiving diagnoses.
