ZIP System Liquid Flashing - STPE Polymer Exterior Sealant (10.3 oz Cartridge)

Overview

ZIP System Liquid Flashing is a professional-grade, fluid-applied sealant designed to create a reliable air and water seal on exterior walls. It is formulated with STPE polymer technology to deliver flexible, durable flashing that adapts to complex wall transitions and irregular surfaces. This sealant is especially suited for rough openings around windows and doors, helping to protect the structure from moisture while maintaining exterior aesthetics.

Designed for hard-to-flash surfaces, ZIP System Liquid Flashing bonds across a variety of substrates and weather conditions. Its robust performance aims to reduce gaps and voids at critical transitions, supporting a tighter building envelope without the need for additional home wraps in many applications.

Key Benefits

• Rough Opening Sealing: Forms a water-tight seal around windows, doors, and complex wall transitions.
• STPE Polymer Performance: Flexible, fluid-applied flashing that accommodates irregular shapes and uneven surfaces.
• Wide Material Compatibility: Bonds effectively to wood, concrete, masonry, metal, glass, PVC, EPDM, and other common exterior materials.
• Weather Protection With Warranty: Creates an air-tight barrier that resists harsh elements and qualifies for the ZIP System 30-Year Limited Warranty.
• ZIP System Dependable Protection: Engineered to deliver a continuous air and water barrier, often reducing the need for additional exterior wraps.

In real-world use, the product is applied at the rough openings and around intricate wall details where traditional flashing might be challenging. The creamy, easy-to-smooth consistency helps installers build a clean seal around corners and transitions, then cures to a flexible film that accommodates movement due to temperature changes and building settling.

Practical Considerations

• Application Context: Exterior walls, window and door openings, and other hard-to-flash areas.
• Material Scope: Works with wood, concrete, masonry, metal, glass, PVC, EPDM, and similar substrates.
• Durability Note: Aims to provide long-lasting sealing performance under normal weather exposure, with eligibility for a long-term warranty.
• Installation Practicalities: Fluid-applied flashing can simplify sealing across uneven or complex wall faces.

While the description highlights potential benefits, outcomes depend on proper surface preparation and installation. Consider ZIP System Liquid Flashing as part of a broader moisture-control strategy to optimize exterior protection and energy performance without promising guaranteed results.
