Intumescent Sealants

Whether there is a gap in masonry, plastic, wood, concrete, ironmongery or plasterboard, an intumescent fire sealant can be used to improve safety and structural integrity.


When exposed to fire, intumescent sealants expand to fill the cavity and resist fire and smoke for up to four hours. For precise and consistent application, you can use a long-lasting foam applicator gun, which offers an adjustable flow rate and increased speed when using the foam.
