Selsil Premium Flex PU Foam provides insulation and airtightness in partition walls, roofs, floors, ceilings of buildings even at low temperatures. It is suitable for joints between gypsum blocks and limestone bricks. It is also suitable for joints with vibrations and small movements such as air ducts and pipe penetrations.
The application surface must be solid, clean, dry and free of dust, oil and grease. The most suitable can temperature for use of PU foam is between 20–25°C. Moistened surface provides better results. Low temperature cans should be used after storage at room temperature for a period of time (20 min).
Shake the tube vigorously about 30 times before use. Hold the foam can upside down during the application. Screw the can to the gun. The foam amount can be adjusted with the trigger. Fill the cavity for 70%, the foam will expand to fill the rest. The foam should be applied layer by layer if joints are wider or deeper than 4 cm. Wait 15–30 minutes between applications. Before each application lightly spray with water.
During application, clean the gun if foam residue accumulates on it. After application, the gun should be cleaned with Selfix Foam Cleaner.
Not suitable for PE, PP, PC, PMMA, PTFE substrates.
Do not use in applications where continuous water immersion is possible.
Fresh foam can be cleaned with Selfix Foam Cleaner before curing. The cured foam may be removed mechanically.
Cured foam will discolor if exposed to UV, therefore paint or coat the cured foam for best results in outdoor applications.
The curing process is dependent on temperature and humidity. Lower temperatures decrease yield and increase curing time.
