For insulating and filling window joints, pipe openings, wall openings, wall joints, cavities, refrigerated trucks, walk-in refrigerators, roof finishing, roller shutter boxes and window sills.
Shake can vigorously 20 times before use. Surfaces must be clean, solid and free from dust and grease. Prime highly absorbent substrates. Adhesion surfaces must be moistened with water before the foam is applied. Moisten again if several foam beads are applied. Screw the can all the way into the gun support - do not screw too far or tilt. Foam continues to expand after application. Immediately remove splashes of foam with PURLOGIC CLEAN, art. no. 0892 160. Thoroughly clean the gun and valve after use. If you need to interrupt your work, leave the can attached and turn the dosing screw all the way to close and seal the gun. If the gun is not intended to be used for a prolonged period of time, it needs to be rinsed as follows: Quickly screw the PU foam cleaner with the screw adapter onto the gun. Actuate the outlet until clear liquid comes out. In addition, carefully remove foam residue from the outside of the gun using PU foam cleaner. The contents of the can must be used within 4 weeks.
