    Selleys Pro-Trade Expanding Foam - 750ml

    Selleys Pro-Trade Expanding Foam is a high-performance filler expanding foam designed to fill gaps and holes in walls, ceilings, doors, and windows.

    • Once cured, can be sanded, cut, plastered, grouted, caulked, or painted for a seamless finish.

    • Reduces noise, dust, draughts, and prevents pests from entering gaps.

    How to Use

    1. Ensure surfaces are clean, dry, and free from dust and grease.

    2. Shake the Selleys Pro-Trade Expanding Foam 750ml can thoroughly before use.

    3. Attach the supplied nozzle and dispense foam into the gap, filling only one-third as the foam will expand to fill the space.

    4. Allow the foam to cure (approx. 5 hours for painting, full cure may take longer depending on conditions).

    5. Once cured, trim excess foam with a knife and finish as required—sand, plaster, grout, cut, caulk, or paint.

    FAQ

    What are the best uses for Selleys Pro-Trade Expanding Foam?

    Selleys Pro-Trade Expanding Foam is ideal for filling large, irregular gaps and cavities around pipes, skirting boards, architraves, and door/window frames. It expands up to three times its original volume to create a tight seal, insulating against heating and cooling loss. Additionally, it deadens sound and prevents the passage of dirt, water, and pests.

    How do I apply Selleys Pro-Trade Expanding Foam for optimal results?

    Before applying Selleys Pro-Trade Expanding Foam, ensure the surface is clean, sound, and slightly moistened for better adhesion and expansion. Shake the can vigorously, apply from the bottom up while holding the can upside down, and avoid overfilling as the foam will continue to expand. Optimise the expansion while applying by spraying some water, and then allow it to cure before cutting or sanding it.

    How long does Selleys Pro-Trade Expanding Foam take to cure and can I paint it?

    Selleys Pro-Trade Expanding Foam is tack-free in about 5 minutes and can be cut or sanded after approximately 30 minutes. It becomes fully paintable in about 3 hours, allowing you to seamlessly integrate the repaired area with its surroundings. However, as it is sensitive to ultraviolet radiation, apply a coat of paint if it is going to be exposed to direct sunlight.
