FS702 is suited for use around non-combustible services, cables, and rock fibre insulated non-combustible pipes, with a minimum depth of 25 mm. It has excellent adhesive qualities and can also be used for bonding and pointing joints and service penetrations, particularly in conjunction with the FB750 Intubatt system.

How is Nullifire FS702 installed?

FS702 is applied using a standard caulking gun into joints, gaps, or around service penetrations. The area should be clean and dry before application. The sealant should be smoothed for even coverage and adherence. Follow the manufacturer’s guidelines for the correct depth and width of application.

Can Nullifire FS702 be used for sealing around service penetrations?

Yes, FS702 is specifically designed for sealing around cables, pipes, ducts, and other mechanical service penetrations, providing a fire-resistant seal.

How does Nullifire FS702 contribute to fire safety?

FS702 expands when exposed to high heat, creating a fire-resistant barrier that prevents the spread of flames and smoke through joints and service penetrations. This containment helps to compartmentalise fires and protect building occupants.
