PENOSIL
Polystyrol FixFoam 877 Foam adhesive for insulation boards

VALUES

• Great adhesive properties
• Works in all weather conditions
• All season (-5°C to +30°C)
• Easier, faster, cleaner than traditional adhesive mortar
• Low curing pressure and post expansion
• Thermal and sound insulation
• Strong structure

USAGE INSTRUCTIONS

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

Moisten dry surfaces with water mist (only at temperatures above zero degrees) 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 the gun trigger and adjustment screw.

Insulation boards and interior design boards:
Apply the foam adhesive to 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 10 m2 of wall surface can be covered with insulation boards.

Windowsills:
Before fixing the windowsill, make sure the base surface is levelled. Spacers must be used to support the windowsill; foam can only be used as an adhesive.
Apply foam adhesive onto the base surface 3 to 4 cm from the edge.
Weights must be used to fix the windowsill until the foam adhesive is cured.

TIPS

• Air temperature during use: -5°C to +30°C.
• Always follow building design, building regulations, standards or other relevant guidelines concerning additional mechanical fastening when covering insulation boards with cladding materials.
• Use of insulation support anchors is always recommended.
• Consult with a sales agent, a dealer or an architect regarding compatibility with various stone-based materials and other technical issues.
• 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 -5°C.
• Cured foam needs to be covered with a suitable material to protect against UV rays.
• Not recommended for bituminous surfaces.
• Windowsills must have additional constructional support, foam can only be used as an adhesive.
