How to use ABC Firestop Sealant

  • The joints must be clean and free from dust, grease and rust.
  • No primer is required for non-porous surfaces. On porous surfaces such as concrete, stone, cement and plaster a primer (mixture of one part acrylic sealant and 4-5 parts of water) can be applied.
  • Min/max joint width must be 5mm/25mm. The recommended joint depth/width ratio is 1 to 2.
  • Application temperature is between +5 °C and +35 °C.
  • Immediately after the application, smooth the sealant at once with wet finger or a wet tool. Excess sealant can be removed by a wet cloth.
  • Keep the sealed joint dry at least for two hours.
  • Cured sealant can be removed mechanically.

Damp or humid conditions will significantly extend the cure time.
Do not apply below 5°C
