Bondex All-Purpose Joint Cement (dry-powder chrysotile formulation, 14.8% chrysotile SX / 5% All-Purpose)

Product Description

Bondex All-Purpose Joint Cement in its dry-powder formulation was one of the flagship drywall-finishing products marketed by Bondex International, Inc. (also operating as Reardon Company and later Republic Powdered Metals / RPM International) from approximately 1961 through 1977. Sold in paper bags at hardware stores, building-supply outlets, and through private-label distribution arrangements — including Montgomery Ward, Penncraft, Hi & Dri, NPD, Cook’s Lifeline, Brod Dirgan, F.O. Pierce, Metro, and Trax labels — the product was designed for hand-mixing with water and application by trowel or knife across all three stages of drywall finishing: taping, filling, and topping.

Plaintiffs have alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that the dry-powder All-Purpose Joint Cement was formulated with approximately 5% chrysotile asbestos as a functional additive that improved crack resistance, workability, and set-strength. According to publicly filed asbestos litigation records — corroborated by Bondex’s own documented product-identification disclosures — Bondex sold at least eight distinct asbestos-containing product lines during this era, including SX Joint Cement (documented at approximately 14.8% chrysotile) and Ready-Mixed Joint Cement (approximately 3.8% chrysotile). Warning labels were allegedly added to Bondex packaging in 1972 or 1973, well into the product’s asbestos-containing production run.

Workers Exposed

Plaintiffs allege the following trades were exposed to airborne chrysotile fibers from Bondex All-Purpose Joint Cement:

• Drywall finishers and tapers who mixed the dry powder in buckets, embedded drywall tape, applied fill and topping coats, and — most importantly — sanded dried joints with hand-sanders and pole-sanders. Sanding operations allegedly generated the densest airborne fiber concentrations in the entire drywall trade.
• Painters who patched, feathered, and sanded Bondex joints as part of pre-paint preparation work.
• Carpenters and general trades who used Bondex joint cement for small drywall repairs, remodel patching, and punch-list work on residential, mobile-home, and light-commercial projects.
• Laborers who mixed compound in buckets, swept sanding dust from finished floors, and hauled empty Bondex bags from jobsites — allegedly inhaling settled dust.
