TEKAPUR FIRESTOP 750 ml Fire Retardant Polyurethane Foam
Tekapur Firestop hand held is a one-component polyurethane foam providing good sound and thermal insulation. It adheres well to most construction materials such as wood, concrete, porous concrete, brick, metal and aluminium, but not to polyethylene, silicone and PTFE.
AREA OF USE
It is used in construction industry for sealing, filling, insulating, mounting and installing (electrical installations, wall penetrations, fire door, vaults etc.), especially when greater resistance to burning is required.
Surfaces should be clean, free of dust, grease and other impurities. Dry and porous surfaces should be moistened with water. The optimal temperature of can at work is room temperature. At lower temperature put the can into warm water with max. temperature of 40°C for about 20 minutes. Before use shake can thoroughly with the valve upside down. Remove the protection cap and screw on the nozzle with a tube. Turn the can with the valve upside down and apply pressure on the valve to activate the foam. You only have to fill the gap partially as the foam expands from 2 to 3 times. If you are filling a gap wider than 5cm, work in layers. Apply the second layer once the first one has hardened. You can speed up the process of hardening by spraying the foam with water. Once hardened, foam should be protected against UV light.
Once the foam has hardened, cut it with a sharp knife and finish with plastering, sealing, covering, painting etc. If you do not use the entire can clean the valve with the TEKAPUR cleaner or acetone. Hardened foam can only be removed mechanically.
