Usage Instructions

Surfaces must be clean from dust, loose particles and oil stains.
Moisten dry surfaces with water mist to ensure a 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 onto the gun. Hold the can upside down when extruding the foam. Foam output can be adjusted with a gun trigger and adjustment screw.

Apply the foam adhesive to the board surface in a continuous flow, parallel with the sides of the board (3 to 4 cm from the edge) and one strip in the middle, parallel to the longest side (up to 25 cm between adhesive strips).

After applying the foam adhesive onto the board wait 2 to 3 min and then press the board onto the wall. The board can be adjusted/straightened during the next 5 min.  

With one foam can 7 m2 of wall surface can be covered with insulation boards. The yield in lineal meter is around 34 m (with bead of 2,5 cm).

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

Tips

• Air temperature during use: +10°C to +30°C.
• Always follow building design, building regulations, standards or other relevant guidelines concerning additional mechanical fastening. 
• Use of insulation support anchors is always recommended.
• 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 Cleaning Wipes 941 to clean hands and clothes from uncured foam. 
• Penosil Foam Remover 995 softens cured foam and helps to remove it easier.

Limitations

• Does not adhere to polyethylene (PE), PTFE (Teflon®) or silicone surfaces. 
• Do not use at temperatures below +10°C.
• Cured foam needs to be covered with a suitable material to protect against UV rays. 
• Not recommended for bituminous surfaces.
