General Guidelines

General guidelines when using Kay-Cel Core

  • Store Kay-Cel Core material indoors or protect from sunlight.
  • Can be cut with normal woodworking tools.
  • Wear dusk mask, eye protection, and gloves when cutting.
  • Can be use with a wide variety of resins.
  • Do Not burn material.
  • Best practices:
    • Maintain dry, clean surface for maximum bonding.
    • Pre-wet boards with resin before applying fiberglass.
