A short Soudal video on caring for, cleaning and maintaining your PU foam gun.
Clean the gun with Soudal Gun & Foam Cleaner: screw the can onto the gun and pull the trigger to flush uncured foam out before it can block the gun. Between jobs you can leave the gun on the foam can with the nozzle screw tightened. Cured foam can’t be dissolved, only cut or scraped off.
