Flintkote Weld-On Cement: Product Reference
Product Description
Flintkote Weld-On Cement was a construction adhesive and bonding compound manufactured by The Flintkote Company, a building materials manufacturer that operated for much of the twentieth century. Flintkote was one of the larger producers of asbestos-containing building products in the United States, with a product line that spanned roofing materials, floor tiles, ceiling tiles, pipe insulation, cement pipe, and joint compounds. Weld-On Cement represented one entry in that broader catalog — a heavy-duty adhesive cement intended for use in industrial and commercial construction applications.
Products marketed under the Weld-On name were designed to bond, seal, or adhere construction materials in demanding environments, making them common on job sites where workers encountered the product during installation, maintenance, repair, and demolition work. Because Flintkote operated across multiple product categories simultaneously, Weld-On Cement was often used alongside other Flintkote materials, increasing the potential for cumulative exposure on any given worksite.
The Flintkote Company was eventually acquired and restructured, and its asbestos liabilities became the subject of extensive litigation and bankruptcy proceedings. Today, claims involving Flintkote products — including Weld-On Cement — are addressed through the legal and litigation framework established as a result of those proceedings.
Asbestos Content
Flintkote incorporated asbestos into a wide range of its building and construction products during the mid-twentieth century, a period when asbestos was widely used in the construction industry for its heat resistance, tensile strength, and binding properties. Cement-based adhesive products from this era frequently contained chrysotile asbestos, and in some formulations, amphibole varieties such as amosite or crocidolite, depending on the intended application and the manufacturer’s sourcing practices.
Litigation records document that plaintiffs alleged Flintkote Weld-On Cement contained asbestos as a functional component of its formulation. According to these allegations, the asbestos content was not incidental but was incorporated to improve the product’s performance characteristics — including its ability to adhere to substrates under high-temperature or high-stress conditions.
Plaintiffs further alleged that the finished product, when disturbed during normal use, could release respirable asbestos fibers into the surrounding air. Because asbestos fibers are microscopic and do not settle quickly, workers in enclosed or poorly ventilated spaces would have faced prolonged exposure during product application or any activity that disturbed cured material.
The specific percentage of asbestos by weight in Weld-On Cement formulations has varied across litigation proceedings, and no single documented figure should be treated as universal across all product batches or production years. Claimants and their legal representatives should consult product testing records, safety data documentation, and deposition testimony from specific litigation files to establish asbestos content relevant to a particular exposure history.
How Workers Were Exposed
Industrial workers generally represent the primary exposed population documented in connection with Flintkote Weld-On Cement. The product’s use across multiple construction categories — including roofing, flooring, ceiling installation, pipe insulation, and cement pipe work — meant that exposure was not confined to a single trade or a single type of job site.
Application workers who mixed, troweled, or brushed Weld-On Cement directly onto surfaces faced the most direct exposure pathway. Opening containers, stirring product, and applying it by hand or tool could disturb asbestos fibers and release them into breathing zones. In enclosed industrial environments such as boiler rooms, mechanical spaces, and pipe chases, airborne fiber concentrations could accumulate without adequate ventilation.
Roofing and waterproofing workers who used cement-type adhesives to bond roofing materials, flash penetrations, or seal seams were regularly exposed to similar products in Flintkote’s line. Litigation records document that plaintiffs employed in roofing trades alleged exposure to Flintkote products during both new construction and re-roofing operations.
Floor and ceiling tile installers worked with adhesive cements as bonding agents beneath tiles, and plaintiffs alleged that Flintkote Weld-On Cement was present on job sites alongside Flintkote floor and ceiling tile products. The combination of multiple asbestos-containing materials in a single work area compounded exposure potential.
Pipe insulation and cement pipe workers — including those involved in the installation and repair of industrial piping systems — used adhesive cements to secure insulation materials and to join or seal pipe sections. Litigation records document that workers in these trades alleged repeated contact with Flintkote products throughout their careers, often in confined spaces where fiber dispersal was concentrated.
Maintenance and demolition workers faced secondary exposure when previously installed Weld-On Cement was disturbed during repair, renovation, or removal work. Friable or deteriorating asbestos-containing cement could release fibers during cutting, grinding, breaking, or abrasion — exposures that may have occurred years or decades after original installation.
Litigation records document that plaintiffs alleged Flintkote had knowledge of the health hazards associated with asbestos exposure but failed to provide adequate warnings on product labels or safety documentation distributed to workers and employers.
Documented Trust Fund / Legal Options
The Flintkote Company filed for bankruptcy protection in 2004, and its asbestos liabilities were addressed through proceedings in the United States Bankruptcy Court. The resolution of those proceedings resulted in the establishment of the Flintkote Asbestos Trust, which was created under Section 524(g) of the Bankruptcy Code to compensate individuals with asbestos-related claims arising from Flintkote products.
Because Weld-On Cement is documented in litigation records as an asbestos-containing Flintkote product, individuals diagnosed with asbestos-related diseases following exposure to this product may have standing to file a claim with the Flintkote Asbestos Trust.
Eligible claimants typically include individuals diagnosed with:
- Mesothelioma
- Lung cancer with documented asbestos exposure history
- Asbestosis
- Other asbestos-related pleural diseases, subject to trust criteria
Filing eligibility generally requires documentation of a qualifying diagnosis, evidence of exposure to Flintkote products, and evidence that exposure occurred within a timeframe consistent with the disease’s latency period. Occupational history records, co-worker affidavits, job site documentation, and union records may all serve as supporting evidence.
In addition to trust fund claims, litigation records document that plaintiffs have pursued direct civil claims against other parties in the asbestos supply chain — including suppliers, distributors, contractors, and premises owners — where Flintkote products were present. These claims proceed independently of the trust process and may be available depending on the jurisdiction and the circumstances of exposure.
Individuals who believe they were exposed to Flintkote Weld-On Cement and have received an asbestos-related diagnosis should consult a qualified asbestos litigation attorney to evaluate all available legal remedies, including trust fund claims, third-party litigation, and any applicable veterans’ benefits programs if exposure occurred during military service.
