Ideal for all applications where fire retardant properties are required,  for example: 

• Installation of door and window frames.
• Filling and sealing gaps, joints and cavities.
• Filling of penetrations in walls.
• Heat insulation of roof construction.
• Sealing of cable and pipe penetrations.
• Soundproofing and sealing partition walls.
• Bonding of insulation materials.
• Multi‐Purpose, adhesion and fixation.

Directions 

• Ensure all surfaces are clean, sound, dry and free from dust, grease or other contaminants.
• Application temperature is between +5 °C and +30 °C. Always wear gloves and goggles when applying.
• SHAKE THE CAN WELL BEFORE USE.
• Moistening the surfaces and the foam improves adhesion and shortens the cure time.
• For the Hand Held version, screw the straw adapter onto the valve, TURN THE  CAN UPSIDE DOWN and activate the foam by pressing the valve. 
• For the Gun Grade version, screw onto an applicator gun, taking care not to overtighten. 
• To apply the foam TURN THE CAN UPSIDE DOWN and press the trigger, the output of the foam can be regulated with the trigger and controlled with the adjustment screw on the back side of the gun.
• Always keep the can upside down during application. 
• Partially fill the holes and cavities, as post expansion will completely fill the hole.
