Uncured foam can be cleaned using a specialized PU foam cleaner or acetone. Wipe away any excess immediately.
Cured foam is very difficult to remove completely. It can be mechanically removed by cutting or sanding. Specialized removers may be available but often require significant effort.
Yes, once the foam is fully cured, the surface can be painted to match surrounding areas.
Refer to the product packaging for the exact expiration date. For optimal performance, it is recommended to use the product within the recommended period after purchase.
The foam is waterproof and mould-resistant, making it suitable for many outdoor applications where it will be protected from direct UV exposure. However, prolonged direct sunlight may degrade the foam over time.
The foam has a high expansion rate, meaning it can expand significantly to fill voids. The exact expansion volume can vary, but it is designed to provide higher yield and fill large areas efficiently.
Avoid exposure to open flames or high temperatures. Wear gloves and eye protection during application. Ensure good ventilation. Refer to the product label for detailed safety and handling instructions.
Ensure the straw adapter is securely attached. Shake the can vigorously. If the temperature is cold, warm the can in warm water.
Check that the application surface is clean, dry, and free from dust, grease, or loose particles. Ensure the foam is fully expanded.
Do not overfill the gap; the foam expands significantly. Apply in layers if necessary for deep voids. Ensure the can is shaken properly.
Ensure the can was shaken adequately and used at an appropriate temperature. Avoid using in extremely humid or dry conditions without proper ventilation.
Setup: Shake the can vigorously for at least 20 seconds before use. Ensure the surface is clean, dry, and free from dust or grease. Screw the straw adapter securely onto the can valve. Invert the can to dispense the foam. For best results in cold weather (below 5°C), place the can in warm water for 15-20 minutes.
Compatibility: The foam adheres well to most building materials including concrete, plaster, brick, wood, and metal. Avoid use on silicone, Teflon, or polyethylene.
Care: Store the can upright in a cool, dry place, away from direct sunlight and sources of ignition. Use within the recommended period after opening for optimal performance. Once cured, excess foam can be cut with a sharp knife. The cured surface can be painted.
