No mixing required—this pre-mixed cement is ready to apply straight from the container. Designed for high-temperature applications, it’s perfect for bonding, sealing, patching, and repairing masonry and metal surfaces with ease.

đź”§ Application Instructions

  • Apply in thin layers: Do not exceed ÂĽ inch thickness to ensure proper curing.
  • Curing conditions: Ideal temperature range is 60°F to 80°F for up to 24 hours.
  • Adheres to metal surfaces, including aluminum. For best results:
  • Scuff the metal surface before application
  • Clean thoroughly using lacquer thinner.

 

đź§Ľ Cleanup & Handling

  • Wipe away excess with a damp cloth before it dries.
  • If the product dries out in the tub, add a small amount of water to rehydrate.

  • Water-soluble and not flexible—dries to a hard cement
  • Not recommended for stove pipes or areas that expand and contract with heat. For those applications, use:
    • Silicone sealant or
    • Direct vent sealant, depending on temperature requirements
  • For higher temperature ratings, use Refractory Cement
  • Color may whiten when exposed to heat
  • Not an adhesive
  • To bond firebricks to cinder block, use Castable Refractory Cement
