Product Identity

DAP Extreme Stretch is an acrylic urethane elastomeric sealant supplied in a 10.1 fl oz cartridge. It stretches over 600% to seal gaps up to 3 inches wide while remaining crack-proof. The formula provides a 100% waterproof and weatherproof seal on interior and exterior surfaces. It suits homeowners and tradespeople needing flexible, paintable joints.

Compatibility Check

Verify that the substrates match the listed materials such as wood, aluminum, most metals, stone, vinyl, most plastics, drywall and brick. Ensure the joint width does not exceed the 3 inch maximum. Confirm the project can accommodate a two hour paint-ready window and that VOC compliance meets local requirements. The product carries a California Proposition 65 warning for listed chemicals.

Ideal Users

This sealant fits DIYers and professionals sealing windows, doors, trim, molding, sinks and countertops where high elasticity and multi-material adhesion are required. It is less suited for buyers who need a non-paintable silicone formula or those requiring a sealant certified for continuous underwater immersion. Users wanting a smaller cartridge size should consider other packaging options.

Questions about this item

Does the 10.1 fl oz tube come with a nozzle or do I need to buy a caulk gun separately?

The tube is a standard cartridge that requires a separate caulk gun; a built-in nozzle is not included.

How do I know if the Iron Stone colour will match my trim once painted?

The sealant is paint-ready in two hours, so you can top-coat it with any trim colour for an exact match.

What does the 600% stretch figure mean when I am sealing a 3 in. gap?

It means the cured bead can elongate to more than six times its original width, keeping a waterproof seal even as the joint moves.
