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.

Attach the spray applicator onto the tip of the foam gun. Shake the can vigorously at least 20 times. Hold the foam can in an upright position with the valve up. Hold the foam can adapter in place with your fingers while screwing the can onto the gun. Hold the can upside down when extruding the foam. Foam output can be adjusted with gun trigger and adjustment screw. Rotate the spray applicator as needed.

Apply the foam from approx. 40 cm distance. One foam layer's thickness is max. 2 cm. Wait at least 30 min before applying the next layer. Number of layers is not limited. When applying foam in layers, moisten slightly between each layer. Excess foam can be cut off after it has fully cured.

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

Tips

• Air temperature during use: +10°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.
