A water-based intumescent acrylic sealant used to provide a fire-rated linear joint or gap seal, and to maintain the fire rating of walls and floors where they have been penetrated by services.
Used for sealing QuelStop Fire Batts (specified separately).
Mineral wool (minimum 80 kg/m³) or polyethylene (PE) backing rod, where required, can be used as a backing material to ensure the correct depth of sealant is applied in order to achieve the required performance.
The intumescent acoustic sealant should not be applied if the ambient temperature is below 5°C or above 40°C, as the adhesion may be impaired.
The sealant is fast curing, approximately 15–60 minute tack free time, depending on the temperature and humidity. When fully cured, the sealant can be overpainted if required.
