BOSS Fire offer the best-performing and highest-quality fire mastic on the market.

With an FRL of -/300/300 for most applications, FireMastic-300 is unrivalled. And because it's intumscent, it's more efficient and requires half the volume of sealant than most other brands to achieve the required FRL.

As an acrylic emulsion, FireMastic-300 is simple to use and cleans up easily in water.
