“Building sealants are the front line of defense against air infiltration into homes and buildings,” said subcommittee member Morton Jones, director of R&D, Caulks and Adhesives, Gardener-Gibson, Largo, Fla. “Mold spores in the air will attack any surface where moisture and nutrients exist. Mold growth reduction in building structures is a significant human health concern. Sealant mold resistance claims should be appraised and validated.”
The task group invites feedback from sealant producers on a number of issues, including what is the best protocol(s) to evaluate a sealant’s mildew resistance, what classifications describe mold resistance, and what are the physical property changes to address.
