CSR FireSeal is a superior light grey sealant with high acoustic and fire rated properties, suitable for use in commercial and residential building construction.

Product Overview

CSR FireSeal is a PSA composite, non-slumping, low VOC, low modulus, fire and acoustic sealant manufactured to stringent product specifications.

It contains a UV-indicator that glows when subjected to UV light, to enable easy identification by site inspection that the correct product has been used.

 

Typical Applications

CSR FireSeal is suitable as an acoustic sealant between common building materials such as concrete, masonry, Hebel, plasterboard, fibre cement, metals, and timber. It can be used as a fire-resistant seal around pipes, conduits, cable trays and ducts which penetrate walls and ceilings, as well as in control joints and perimeter junctions in plasterboard walls.

*CSR Gyprock only support the use of Gyprock FireSeal sealant when used as part of specified Gyprock systems as noted in our literature.

Installation Instructions

Usage Notes

Substrates must be clean, dry and free from oil, grease, release agents, dust and loose material.

Extrude sealant smoothly into joint, while ensuring that all substrates are well wetted out with sealant.

The sealant cures by water evaporation; therefore cure rate is dependent on humidity, ambient temperature and joint size.

Typically, the sealant will form a thick skin within 24 hours and full cure can be expected after 7 days.

In humid or cool conditions the sealant cure will be longer.

Allow the sealant to form a thick skin before painting with a flexible paint.

To avoid paint cracking, the sealant should be allowed to fully cure before painting with flat and/or ceiling paint.    

Clean Up

Clean tools and equipment in water before the sealant cures. To remove cured sealant, tools will need to be soaked in water followed by mechanical action.
