Dap Inc 756 Auto Marine Silicone Sealant 2.8 Oz

Product Description

The DAP INC 756 is a 2.8 oz tube of 100% silicone rubber sealant formulated for automotive and marine maintenance and repair applications. This sealant bonds and seals surfaces to create a waterproof, weatherproof barrier that stays flexible after cure. It resists vibration, expansion, and contraction, making it well suited for environments where movement and moisture exposure are constant. HVAC, plumbing, and marine service professionals reach for silicone sealants like the 756 when a durable, long-lasting seal is required in areas exposed to the elements or mechanical stress.

The DAP INC 756 is designed for use in automotive and marine maintenance and repair settings. Typical applications include sealing seams, joints, and penetrations on vehicles, boats, and related equipment where water intrusion or weathering is a concern. Its flexibility after cure means it performs in areas subject to regular movement or thermal cycling without cracking or shrinking over time. The product is sold in a package quantity of six units, making it practical for shop or fleet service environments that go through sealant regularly.

Installation Notes

Surface preparation is critical before applying silicone sealant — clean and dry all surfaces thoroughly to ensure proper adhesion. Allow adequate cure time before exposing the seal to water or mechanical stress. When working on vehicles or marine vessels, disconnect power sources and follow all applicable safety procedures before beginning repairs involving sealant near electrical components.
