SikaSeal® Fire Guard

For maintaining fire wall integrity

SikaSeal® Fire Guard is a four-hour rated, one part, water based, ablative acoustic sealant that gives a firm yet flexible seal to joints in a variety of internal fire-rated structures. The product, in suitably designed joints, will resist the passage of fire for up to 4 hours. 

  • When exposed to heat, SikaSeal® Fire Guard swells greater than 150 % of its original size, creating a char that will resist the passage of fire for up to 4 hours.
  • No priming required for most construction substrates.
  • Permanently flexible with more than 100 % elongation to ISO 8339.
  • For fire resistant joints 12 to 50 mm wide.
  • Excellent acoustic properties for sound deadening; average noise reduction of 24 dB (100-3150 Hz).
  • Non slump - easy to apply and tool off.
  • Fast cure - tack free in 15 minutes.
  • Overpaintable.
