QuelStop QSS310 Intumescent Acrylic Sealant 310ml (White)

QSS QuelStop Intumescent Acoustic Acrylic Sealant is a water-based intumescent acrylic mastic 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 as part of the QuelStop Fire Batt System or direct to the substrate.

On exposure to fire, it expands to reinstate the integrity of the compartment, preventing the spread of fire for the amount of time it has been proven to during testing.

Application:
QuelStop Intumescent Acrylic Sealant is a fundamental part of the QuelStop Fire Batt System and should be applied to all cuts, joints and exposed edges of the batt. It can also be used for sealing around services such as cables, cable bundles, trays, ladders and non-combustible pipes, either as part of a seal directly within the wall substrate or as part of a QuelStop Fire Batt Seal.

QuelStop Intumescent Acrylic Sealant can also be used as a linear joint seal in a range of applications between concrete and concrete, steel or softwood, to a gypsum board headtrack and around wooden fire door frames.

Installation:
All surfaces must be clean and free of any bond-breaking contamination prior to application of the sealant.

The sealant should not be applied if the ambient temperature is below 5°C or above 35°C, as adhesion may be impaired.

The sealant is fast curing, with an approximate tack-free time of 15–60 minutes, depending on temperature and humidity.

In linear joint applications, mineral wool or PE backing rod may be used as backing material to ensure the correct depth of QuelStop Intumescent Acrylic Sealant is applied to achieve the required performance.

For full details on application and installation, refer to all available documentation and the Quelfire Technical team.
