DAP has taken the guesswork out of choosing sealants, adhesives, and foam. Each of the seven products in The Spec Line is designed to help professionals meet industry specifications for a particular job — and the product name references that spec. (DAP Dynaflex 920, for example, is an exterior elastomeric sealant that meets industry specification ASTM C920.) The product line contains three categories: Dynaflex sealants, Dynagrip adhesives, and Draftstop foam. Prices range from $4.50 to $14. DAP Products, 888/327-8477, dap.com.
