ZIP System Liquid Flash, 10.3 oz Cartridge – Weather-Resistant Flashing Sealant

Overview

ZIP System Liquid Flash is a high-performance flashing sealant designed for building penetrations and joints. It forms a lasting air- and water-tight barrier that stays resilient against harsh weather exposure.

Engineered to flash and seal penetrations permanently, it bonds to damp or dry surfaces, reducing the need for multiple products on the job. This flexibility helps maintain momentum when conditions shift from dry to damp during weather changes.

Key benefits

• Creates an air- and water-tight seal that resists harsh elements, helping protect exterior joints.
• Permanently flashes and seals building penetrations, reducing the likelihood of future leaks.
• Bonds to both damp and dry substrates, expanding where you can apply it.
• Supports compatibility with most urethane, silicone and acrylic sealants for integrated flashing systems.
• Quick cure time, allowing finishes to progress in as little as 20–40 minutes depending on conditions.

Real-world scenarios

On a busy job site, ZIP System Liquid Flash can be applied around vent pipes, electrical conduit, and roof-to-wall transitions to create a continuous barrier. The ability to work across damp or dry surfaces helps maintain momentum when the weather shifts, reducing downtime.

• Vent and pipe penetrations: helps seal around irregular shapes and corners.
• Siding and trim junctions: provides a reliable flashing layer before final finishes.
• Roof edges and parapet transitions: contributes to a durable edge seal against moisture intrusion.
