    The superior 5-hour sealant offers the best fire rating of all acrylic and PU sealants on the market.  BOSS FireMastic-300 offers maximum protection from fire and smoke in both integrity and insulation.

    FireMastic-300 intumescent Fire-Rated Acrylic Sealant is a one-part acrylic emulsion that is designed to resist the passage of fire, smoke and sound. When exposed to fire heat, FireMastic-300 will intumesce and form a char preventing the passage of fire and smoke for up to 5 hours.

    FireMastic-300 is first choice within the industry as it offers maximum protection, reduced costs and as an acrylic emulsion, is simple to use and cleans up easily in water.
