USAGE INSTRUCTIONS

Surfaces must be clean from dust, loose particles and oil stains.

Shake the can vigorously at least 20 times. Remove the cap. Hold the foam can in an upright position with the valve up. Screw the straw applicator tightly onto the foam can valve.

Hold the can upside down when extruding the foam. Foam output can be adjusted with the applicator trigger.

Fill the joints up to approx. 50%. In the case of larger joints, apply foam in several layers. Excess foam can be cut after it has fully cured.

Tips

• Air temperature during use: +5°C to +30°C.
• 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 of uncured foam.
• Use Penosil Cleaning Wipes 941 to clean hands and clothes of uncured foam.
• Penosil Foam Remover 995 softens cured foam and helps to remove it easier.

Limitations

• Does not adhere to polyethylene (PE) or PTFE (Teflon®) or silicone surfaces.
• Do not use at temperatures below +5°C.
• Although the cured foam is less sensitive to UV and direct sunlight than other PU foams, it is still recommended to cover it with a suitable opaque material.
• Do not cover before foam has fully cured.
