    1. Wear protective gloves. Ensure surfaces are free from dust, dirt or debris.
    2. Before using, make sure that the can temperature is above zero (optimum +20°C). Application temperature from +5°C up to +30°C.
    3. Shake can vigorously for 30 seconds to mix properly components.
    4. Screw gun onto the can. Hold can upside-down during application.
    5. Moisten surfaces with water prior to application.
    6. Fill gaps from down to up, zigzag motion, alternating from one wall to the other. Fill gaps to approximately 60 % volume. Max. wide of the gap 3-4 cm. Wider gaps should be applied after hardening of the previous layer. Each layer should be moistened with water using a spray.
    7. After full curing, cut the excess foam with a knife and protect it from UV exposure by coating with plaster, paint, acrylic or silicone.
    8. In the event of a stoppage exceeding five minutes duration, wipe the nozzle with cleaner for foam applicator.
    9. After removing the applicator gun from the can, wipe down the nozzle and gun (internal and external surfaces) using a cleaner.
