|Where to use
Shake the can vigorously for 30 seconds. Screw the threaded basket end of the gun onto the valve. Care must be taken not to over tighten the dispensing assembly. During processing, the can must be held inverted with the valve in bottom position. To extrude the foam, pressure has to be carefully applied to the gun trigger. The gun trigger can be adjusted by turning the round knob at the rear of the gun dispenser. The fresh foam will expand after application, therefor care must be taken not to overfill joints. Please note: Moisture is needed for an even and rapid curing of the foam. Inadequate moistening or overfilling of joints and cavities may lead to poor cure or unwanted excessive post-expansion of the foam. In the case of gaps larger than 3 x 3 cm, it is recommended to fill by applying several layers of foam, allowing each to cure.
