A-B Tex Texture Paint

Product Description

A-B Tex Texture Paint was a decorative and finish coating product manufactured by United States Gypsum Company (USG), one of the largest gypsum and construction materials producers in the United States. Marketed primarily to commercial construction contractors and finishing tradespeople, A-B Tex Texture Paint was designed to produce textured surface finishes on interior walls and ceilings, providing both aesthetic variety and surface concealment for imperfections in underlying drywall or plaster substrates.

USG produced A-B Tex Texture Paint from approximately 1935 through 1974, a period spanning nearly four decades during which asbestos was widely used as a functional additive in construction coatings and finishing materials. The product belonged to a broader category of joint compounds, texture coatings, and finishing products that relied on mineral fiber content to improve workability, bonding strength, and surface durability. A-B Tex Texture Paint was applied by brush, roller, or spray equipment on job sites across the country, appearing in commercial buildings, industrial facilities, schools, and institutional construction projects throughout its production run.

The product’s discontinuation in 1974 aligns closely with the period during which federal regulators and public health authorities began mandating the removal or prohibition of asbestos from construction materials, culminating in the Environmental Protection Agency’s later regulatory actions under the Asbestos Hazard Emergency Response Act (AHERA) and related statutes.

Asbestos Content

A-B Tex Texture Paint contained chrysotile asbestos, the most commercially prevalent form of asbestos used in the United States during the twentieth century. Chrysotile, sometimes referred to as “white asbestos,” is a serpentine mineral fiber that was widely incorporated into construction products for its heat resistance, tensile strength, and binding properties. In texture paints and finishing coatings, chrysotile fibers served multiple functional purposes: they improved the product’s spreadability and adhesion to surfaces, reinforced the dried coating against cracking, and contributed to the textured finish that distinguished such products from standard flat paints.

During the decades A-B Tex Texture Paint was produced, the incorporation of asbestos into construction coatings was standard industry practice and largely unregulated. United States Gypsum Company, like other major construction material manufacturers of the era, formulated its texture and finishing products with asbestos content that is documented in product records and litigation materials. Chrysotile fibers, when dry or disturbed, are capable of becoming airborne and remaining suspended in workplace air for extended periods, creating inhalation hazards for workers handling or working near such materials.

How Workers Were Exposed

Industrial workers and construction tradespeople who handled, mixed, applied, or worked in proximity to A-B Tex Texture Paint during its production years faced potential asbestos exposure through several distinct pathways.

Mixing and preparation presented one of the most significant exposure risks. Workers who opened bags or containers of texture paint and combined the product with water or other components could generate visible dust clouds containing chrysotile fibers. This dry mixing process — common on job sites before spray application — released concentrated amounts of asbestos-bearing particulate into the immediate work environment.

Spray application was another high-exposure activity. Texture coatings applied by spray equipment aerosolized the product mixture, dispersing fine particles, including asbestos fibers, into the surrounding air. Workers operating spray equipment and those working in adjacent areas could inhale airborne fibers during and after application, particularly in enclosed or poorly ventilated interior spaces.

Sanding and surface finishing of dried texture coatings created additional exposure. When workers sanded or abraded dried A-B Tex Texture Paint to smooth or blend finished surfaces, the mechanical action broke apart the dried coating and re-released chrysotile fibers into the air. Sanding asbestos-containing texture products is recognized by occupational health authorities as among the more hazardous activities associated with such materials.

Cleanup and debris handling also contributed to worker exposure. Sweeping dried material, disposing of product residue, or working on floors and surfaces covered with settled dust from texture paint application could disturb settled asbestos fibers and return them to the air.

Beyond direct applicators, workers in shared job site environments — including other trades working in the same building spaces — could be exposed to asbestos released by nearby texture paint operations without themselves directly handling the product. Industrial workers in facilities where A-B Tex Texture Paint was applied during construction or renovation similarly faced bystander exposure risks.

OSHA’s current permissible exposure limit (PEL) for asbestos is 0.1 fibers per cubic centimeter of air as an eight-hour time-weighted average. Historical job site conditions during the decades A-B Tex Texture Paint was in use typically lacked the engineering controls, respiratory protection, and exposure monitoring that modern regulations require.
