Dap Inc 1801 Gutter Flashing Sealant 10.1 Oz White

Product Description

The DAP INC 1801 is a 10.1 oz cartridge of advanced-formula gutter and flashing sealant designed to create a durable, flexible, watertight bond on exterior metal and roofline components. This white sealant is formulated to hold up against extreme weather and temperature swings, making it a reliable choice for sealing joints that are constantly exposed to moisture, thermal cycling, and UV stress. Roofers, siding contractors, and general contractors use this product to seal vulnerable connection points where water intrusion is a primary concern. The VOC-compliant formula meets regulatory requirements for professional application in most markets.

This sealant is suited for residential and light commercial roofing and exterior applications. It works across a range of substrates and joint types commonly encountered during gutter installation, flashing work, and siding repair. Typical use cases include sealing gutter seams, attaching or resealing downspout connections, bedding lap joints in aluminum siding, sealing around roof vents, and finishing flashing transitions at roof edges, valleys, and penetrations. The product ships in a standard 10.1 oz cartridge compatible with a standard caulk gun.
