DAP DynaFlex 920 Premium Exterior Elastomeric Sealant delivers superior flexibility and adhesion for demanding outdoor applications. This premium-grade sealant bonds to wood, vinyl, aluminum, masonry, and most common building materials without priming. The elastomeric formulation stretches and recovers with building movement while maintaining a watertight seal.

Available in multiple colors to match siding and trim, DynaFlex 920 provides excellent UV resistance and weatherability for long-term exterior performance. The sealant cures to a durable, paintable finish that resists cracking, shrinking, and chalking. Its advanced formula meets ASTM C920 standards for elastomeric joint sealants.

Ideal for sealing gaps around windows, doors, siding, trim, and other exterior joints where movement occurs. Works well for weatherproofing applications on residential and commercial buildings. The 10.1 oz cartridge size fits standard caulk guns for easy application.
