  • 100% neutral silicone
  • ASTM C920 (Class 50) compliant
  • Weatherproof seal
  • Permanently flexible
  • Indoor and outdoor use
  • Matte finish

Joint design

  • The specified sealant bead size should be calculated to comply with the compression and extension capabilities of the sealant in relation to the anticipated joint width due to expansion and contraction.
  • Generally, calculation of the width sealant bead should be computed on the basis of a maximum ±50 % movement capability
  • Minimum joint depth should not be less than 6 mm to accommodate movement.
  • Silicone Sealant design joint width-to-depth ratio should be 2:1.

Usage instruction

1. Surfaces must be clean, dry, and free of dirt, grease, oil, or water.
2. Surfaces should be cleaned with alcohol, M.E.K., or other suitable solvents. Do not use soap or detergent.
3. For a neat finish, apply masking tape and remove it before sealant skins over.
4. Cut the nozzle at a 45° angle to the desired bead width and apply it to a substrate with a sealant application gun.
5. Tool the sealant within 10 minutes of extrusion before it skins. Tack-free in 20 minutes.
6. Uncured sealant can be cleaned up with mineral spirits.

Clean up

  • Wet sealants can be cleaned up with acetone or mineral spirits.
