Application Details
Surface Preparation
- Surfaces must be clean, sound, frost-free, and free from oil, grease, and loose particles.
- Roughened surfaces improve adhesion.
- Remove curing compounds, sealers, or coatings.
- Use bond breaker tape or backer rod as needed.
- Priming typically not required except in submerged conditions.
Application Instructions
- Temperature Range: 40°F to 100°F
- Joint Design: Width-to-depth ratio of 2:1; minimum depth ¼", maximum ½"
- Insert nozzle to bottom of joint and apply in steady flow to avoid air entrapment.
- Tool immediately to ensure full contact and remove excess material.
- Paintable after full cure (7 days recommended).
- Use opened units the same day to avoid premature curing.
Cleanup
- Clean tools and equipment with xylene before material cures.
- Cured sealant must be removed mechanically.
