The Versico Flexible Dash Adhesive is a specialized bonding product designed for securing edge details and dash applications on commercial roofing membranes. Specifically formulated to work with Versico’s EPDM and TPO systems, this adhesive provides strong, flexible bonds that accommodate thermal movement and weather exposure. This article explains its key features, recommended applications, installation guidelines, and practical considerations to help roofing professionals maximize performance and longevity.
Overview
Versico Flexible Dash Adhesive is a solvent-based or waterborne bonding solution engineered for dash applications along roof edges, curbs, and penetrations. Its primary purpose is to deliver robust adhesion to membrane substrates while maintaining flexibility to absorb movement caused by temperature shifts and building dynamics. The adhesive is compatible with Versico membranes and is typically applied in controlled conditions to ensure proper cure and performance. Understanding its role in edge detailing helps operators choose the right adhesive for durable, watertight seaming and trim work.
Features And Benefits
- Flexible Bonding tolerates membrane movement without cracking or losing adhesion, reducing maintenance needs.
- Strong Substrate Adherence adheres well to EPDM and TPO membranes as well as common deck substrates used in commercial roofs.
- Cold Weather Performance maintains adhesive properties within a broad temperature range, aiding installations in varying climates.
- Chemical Compatibility resists typical roofing contaminants and weathering agents found at roof edges and details.
- ELS/Low VOC Profile supports safer worker environments and aligns with certain project environmental requirements.
Applications And Installation Guidelines
Typical uses include bonding dash strips, edge details, and related curb or penetration details on Versico EPDM and TPO roofs. The installation process generally involves surface preparation, uniform adhesive application, and controlled assembly to ensure full contact and proper curing. Workers should follow the technical data sheet for surface prep recommendations, reducer use (if applicable), open time, and cure conditions. Proper ventilation, personal protective equipment, and adherence to safety data sheets are essential during application.
- Surface Preparation: Clean and dry substrates; remove dust, oils, and loose materials to maximize adhesion.
- Adhesive Application: Apply in a continuous bead or as directed by the product datasheet to ensure full membrane contact.
- Assembly: Position dash or edge components promptly to capitalize on open time and ensure even pressure across the bond.
- Pressure And Curing: Apply uniform pressure during set and protect from rain or excessive moisture until cured per guidelines.
Compatibility And Storage
The adhesive is designed for compatibility with Versico EPDM and TPO membranes and is typically used in conjunction with other Versico edge detailing products. Before selection, verify substrate compatibility, weather conditions, and project specifics with the latest Versico technical data. Store in a dry, cool place away from direct sunlight and ignition sources. Ensure containers are sealed tightly to prevent solvent loss and maintain shelf life according to the product label.

Performance, Durability, And Codes
In service, Versico Flexible Dash Adhesive aims to provide long-term bond durability under roofing temperature cycles and moisture exposure. The product should meet relevant industry standards for roofing adhesives and comply with project-specific code requirements. For best results, installers should follow the recommended cure times, substrate preparation steps, and environmental controls as specified in the official data sheet. Regular inspection of edge details after installation helps confirm ongoing adhesion and performance.
Safety, Environmental Impact, And Handling
Handling involves standard solvent- or waterborne adhesive safety practices, including PPE such as gloves and eye protection. Adequate ventilation is necessary during application and curing. The adhesive’s environmental profile should be reviewed through the product’s safety data sheet and the project’s sustainability requirements. Proper disposal of containers and any waste materials should comply with local regulations and site policies.
