PENOSIL
Window & Door Gunfoam 173 All season installation gun foam

VALUES

• Low curing pressure
• All season (-5°C to +30°C)
• Excellent air tightness and sound insulation properties
• Prevents thermal bridges
• High mechanical strength
• High yield

USAGE INSTRUCTIONS

Surfaces must be clean from dust, loose particles, ice and oil stains.
Moisten dry surfaces with water mist (only at temperatures above zero) to ensure faster curing time and better end results. 

Shake the can vigorously at least 20 times. Hold the foam can in an upright position with the valve up. Screw the can to the gun. Hold the can upside down when extruding the foam. Foam output can be adjusted with a gun trigger and adjustment screw. 

Fill the joints up to approx. 65%. In case of larger joints, apply foam in several layers and moisten slightly between each layer. Excess foam can be cut after it has fully cured.

Do not aim the gun at people. Avoid screwing the can to the gun with valve upside down. Do not screw the gun to the can. Do not bend or turn the can during screwing.

TIPS

• Protect adjacent surfaces with paper, plastic film or other suitable material. 
• Due to the wide variety of construction materials, we recommend a preliminary compatibility test. 
• Working at low temperatures, the foam can must be prewarmed to room temperature (around +20°C). 
• Use Penosil Foam Cleaner 929 to clean tools and surfaces from uncured foam. 
• Use Penosil Multipurpose Wipes 943 to clean hands and clothes from uncured foam. 
• Penosil Foam Remover 995 softens cured foam and helps to remove it easier.
• Air temperature during use: -5°C to +30°C

LIMITATIONS

• Does not adhere to polyethylene (PE), PTFE (Teflon®) or silicone surfaces. 
• Do not use at temperatures below -5°C.
• Cured foam needs to be covered with a suitable material to protect against UV rays.
• Do not cover before the foam has fully cured.
