APPLICATION

  • Prior to application, ensure surfaces are thoroughly cleaned, dry, and free from dust, grease, or other contaminants. Remove old silicone with a silicone remover. While most non-porous substrates require no primer, porous substrates should be treated with one. Always conduct adhesion tests before use.
  • Fill any gaps or voids with Alpha Chem Expanding Foam or AlphaChem Joint Backer Rod.
  • Cut the thread and nozzle to the desired size.
  • Apply the sealant using a sealant gun and smooth down with a spatula dampened with soapy water within 5 minutes of application for a professional finish.
  • Clean excess uncured sealant with solvent. Mechanically remove cured sealant.
  • Dispose of all packaging responsibly.

LIMITATIONS

  • Avoid use in completely confined spaces lacking atmospheric moisture necessary for curing.
  • Not paintable.
  • Do not use with PE, PP, PC, PMMA, PTFE, soft plastics, bitumen asphalt, neoprene, and certain organic elastomers.
