Fill and Fix Expanding Foam, available in aerosol form, is a fast-curing single-part polyurethane foam. The Fill and Fix variant comes with attachable nozzles, while the Gun Grade variant is designed for utilization with our line of applicator guns. Upon application, the foam expands up to 50 times its initial volume and increases by 150%. Once fully cured, it allows for cutting, sawing, or plastering after just one hour, given that the working temperatures (can and surfaces) range between +5 to +25°C, ideally at 20°C.
