Dap Inc 18715 Extreme Stretch Urethanized Sealant 10.1 Oz

Product Description

The DAP INC 18715 is a premium urethanized sealant formulated for high-flex sealing applications on interior and exterior surfaces. Sold in a 10.1 oz cartridge in white, this sealant stretches over 600 percent to maintain a durable, watertight bond even as building materials expand and contract with temperature changes. The urethanized formula delivers superior adhesion to a wide range of substrates, resists mold and mildew after curing, and cleans up with water before cure. Low odor makes it practical for occupied or confined spaces. Licensed contractors and experienced DIYers use this product for perimeter sealing, weatherproofing, and general caulking tasks.

The 18715 is suited for both residential and light commercial applications. Common install scenarios include sealing around windows, doors, trim, siding, gutters, and flashing on building exteriors, as well as interior wet areas such as sinks and countertops. The water-cleanup formulation and easy-tooling consistency make it a practical choice for finish carpenters, plumbers, and general contractors working across multiple substrate types in a single project.
