Mubah PU Foam Spray 750ml, Multipurpose Expanding Foam (PU 512)

What it’s used for

• Filling gaps around doors, windows, pipes, wall joints, and cracks in concrete, brick, plaster, and masonry.

• Temporary sealing of small openings where air or water infiltration is an issue (e.g., around cables, conduits, or corner joints).

• Providing thermal and sound insulation in walls, cavities, and service penetrations.

Key features

• Expanding foam technology: The foam expands to fill cavities completely, reaching deep into gaps and creating a tight, durable seal.

• Strong adhesion: Bonds well to concrete, brick, wood, metal, and most plastics, giving a firm, long‑lasting hold.

• Water & weather resistant: Once cured, it resists moisture and many weather conditions (though prolonged direct UV exposure should be avoided or covered with paint or plaster).

• Easy application: The can comes with a controlled spray nozzle; you direct it into the gap, let the foam expand, and then trim excess once cured.

• 750ml large capacity: One can is suitable for multiple small‑ to medium‑sized repairs, making it practical for both DIY users and contractors.

How to use it (simple steps)

1. Shake the can well (roughly 30–60 seconds) with the straw/nozzle attached.

2. Clean the gap – remove dust, loose debris, and water so the foam can stick properly.

3. Fill the gap about 40–50% full; the foam expands to fill the rest. Avoid over‑filling, as it will bulge out and waste material.

4. Wait for full curing (usually 4–12 hours, depending on temperature and humidity), then trim excess foam with a knife or scissors.

5. Optionally paint or plaster over the cured foam if you want a finished, UV‑protected surface.

This product is ideal for plumbers, contractors, and DIYers who need a quick, clean, and effective solution for sealing, insulating, and reinforcing joints and cracks in buildings.
