Application
Application Instructions
Shake the can vigorously for 30 seconds. Screw the threaded end of the straw assembly onto the valve. During application, the can must be held inverted with the valve in bottom position. To dispense the foam, pressure has to be carefully applied to the straw trigger. The fresh foam will expand after application; therefore 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.
