both horizontal and vertical joints in plasterboard and masonry walls, small openings and gaps

the polyurethane foam “GB-F” has been designed for the quick and easy sealing of gaps, holes and expansion joints. Thanks to its expanding action, it can perfectly seal small openings and joints between materials of different kinds. The polyurethane foam “GB-F” forms an insulating cushion which, in the event of fire, chars and is slowly consumed. The polyurethane foam “GB-F” is supplied in a can with a dispensing nozzle to allow easy application. For use, shake for at least 30 seconds and inject into the opening keeping the can nozzle pointing downwards. The application temperature must be between 5°C and 30°C.
