Did you work with DAP asbestos-fibered roofing cement, flashing cement, and plastic roof cement (trowel-grade)? According to publicly filed asbestos litigation records, it allegedly contained asbestos. Here is what it was, who was exposed, and who is responsible. DAP asbestos-fibered roofing cement, flashing cement, and plastic roof cement (trowel-grade), sold from the 1950s until 1980. Plaintiffs have alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that DAP asbestos-fibered roofing and plastic cement allegedly contained chrysotile asbestos as a reinforcing filler and allegedly exposed roofers, sheet metal workers, and building maintenance crews to airborne asbestos during flashing repair and roof cutback work. Chrysotile asbestos fiber allegedly incorporated as a reinforcing and thixotropic filler in trowel-grade asphalt roofing cement, released as airborne dust during troweling of dried residue, cleanup of hardened buckets, and cut-back / re-flashing of aged patched areas on built-up roofs. Workers allegedly exposed around this product included Roofers, Sheet Metal Workers, and Building Maintenance. Asbestos claims are brought against the companies that made the products. If you worked with or around DAP asbestos-fibered roofing cement, flashing cement, and plastic roof cement (trowel-grade) and were later diagnosed with mesothelioma, asbestosis, or another asbestos-related disease, you may have a legal claim against the manufacturer. This is educational information from an independent publisher — not a law firm — and is not legal advice.
Product Description
DAP (originally Dicks-Armstrong-Pontius, later DAP Inc. / DAP Products) was allegedly a major U.S. supplier of consumer and contractor-grade sealants, caulks, and roof coatings sold through hardware wholesalers, roofing distributors, and home-center retailers. Plaintiffs have alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that DAP’s trowel-grade asphalt roofing cement, flashing cement, and “plastic cement” allegedly incorporated chrysotile asbestos fiber as a reinforcing filler that gave the cement its thixotropic non-slump body, ability to bridge cracks, and adhesion to metal flashings and aged asphalt substrates.
According to publicly filed asbestos litigation records, asbestos-containing DAP roofing and flashing cement was allegedly sold in cans, pails, and cartridge tubes from roughly the 1950s until federal and state asbestos-in-consumer-products reforms drove reformulation by around 1980.
