Sika Fire Guard Mate Intumescent Acrylic Sealant – White – 295ml

Sika Fire Guard Mate Intumescent Acrylic Sealant – White – 295ml

The Sika Fire Guard Mate Intumescent Acrylic Sealant – White – 295ml is a water-based, fire-resistant acoustic sealant designed for sealing internal joints and gaps in fire-rated building structures. Its intumescent formulation expands when exposed to high temperatures, forming a protective char that helps restrict the passage of fire for up to 4 hours in suitably designed and tested joints.

Designed for professional construction, electrical and telecommunications installations, this one-part sealant provides a firm yet flexible seal around suitable building joints and openings. With an expansion rate exceeding 150% when exposed to heat, it helps maintain fire resistance in appropriately specified applications. The sealant also offers excellent acoustic performance, providing an average noise reduction of 24dB. Its permanently flexible formulation, with over 100% elongation, accommodates movement within suitable joints while maintaining an effective seal.

Featuring a non-slump consistency and fast-curing formulation, Sika Fire Guard Mate is easy to apply to a range of common construction substrates, with no primer required in most applications. It becomes tack-free in approximately 15 minutes and can be overpainted once fully cured, providing a neat, professional finish. Supplied in a 295ml cartridge, this white intumescent acrylic sealant is suitable for professional fire-stopping, building maintenance and internal installation projects.
