DAP® DYNAFLEX® Gutter & Narrow Seam Advanced Elastomeric Waterproof Sealant

DAP® DYNAFLEX® GUTTER & NARROW SEAM SEALANT is a high-performance, single-component elastomeric sealant that effectively forms a durable, watertight seal for small joints and narrow seams, especially in gutter and flashing applications. It is designed to withstand extreme weather and temperature fluctuations without cracking or losing adhesion. Versatile in application, it adheres well to various surfaces, including common gutter, flashing, and roofing materials, even in challenging conditions such as cold or high temperatures, wet surfaces, and standing water. Rain ready within 30 minutes without washing out, it is 100% waterproof and weatherproof, UV resistant, and won't harden, yellow, shrink or breakdown over time. The sealant offers excellent workability with its easy-to-apply formula, smooth tooling, low odor, and quick rain readiness, enhancing productivity and providing long-lasting leak prevention.

RESOURCES + FAQs

  • Technical Data
  • How does it provide easier workability?

    Dynaflex Gutter & Narrow Seam Sealant is much easier to gun out than competitive solvent sealants, is less stringy, has low odor versus strong solvent-like odors, and comes in easier-to-use packaging that won’t get damaged by rain or transit.

    How does it improve productivity?

    Dynaflex Gutter & Narrow Seam Sealant saves time because it can be applied in adverse weather conditions, so there's no need to wait for a break in the weather to apply. It’s rain ready and paint ready in just 30 minutes. It also fully cures in 24 hours vs 7-14 days like some other sealants, allowing the product to reach its maximum performance faster.

    Is it mold and mildew resistant?

    Yes, when fully cured, the product is mold and mildew resistant.

    Is Dynaflex Gutter & Narrow Seam Sealant non-sagging?

    Yes, Dynaflex Gutter & Narrow Seam Sealant is ideal for both horizontal and vertical applications. It has just the right balance of non-sag and semi-self-leveling characteristics so that it won’t sag in a vertical joint, yet fills narrow horizontal seams without having to tool.
