Before applying Polycell Expanding Foam Polyfilla, ensure surfaces are clean, free from grease and loose material. (Do not apply in very cold or hot temperatures).
To help foam cure and expand, it is advised before application that you lightly moisten your surface using a trigger spray bottle. To get started, shake can vigorously approx. 20 times to mix contents and select applicator nozzle, dependant on bead size required and carefully screw onto valve, taking care not to activate the valve. Hold the can of Polycell Expanding Foam upside down away from your body and face and start filling at the lowest point shaking can from time to time during use.
It is important to remember to NOT overfill - the foam will expand 2.5 times the initial volume extruded. After around 20 mins, foam will be tack free and can be cut, sanded, plastered, or painted after twelve hours and will be fully cured in 12 -24 hours.
(If using more than one layer of foam, spray lightly with water between layers.)
