The new Hilti Intumescent firestop sealant FS-ONE MAX is an improved version of the popular Firestop sealant FS-ONE. It still includes the reliable features of the FS-ONE but now provides for better handling and longer shelf life.
This new W-rated, multi-purpose formulation means this highly versatile product can be used for even more common through penetrations in a variety of base materials including concrete, masonry, and drywall. It is easy to dispense and is available in multiple package types (tubes, foil packs and buckets) to meet a variety of project needs. The 12 month shelf life from date of manufacture helps reduce the risk of expired inventory.
