The Poly Expanding Foam aerosol is a 750g polyurethane foam that expands to fill large, irregular gaps, hollows and cavities. The self-expanding formula reaches into awkward spaces, then cures so it can be trimmed, sanded and painted for a tidy finish.

  • Size: 750g aerosol
  • Colour: White
  • Material: Polyurethane foam
  • Paintable: Yes
  • Stainable: Yes
  • Sandable: Yes

This larger 750g expanding foam aerosol is well suited to bigger filling jobs around frames, pipes and cavities indoors and out. Once cured it can be cut, trimmed, sanded, stained and painted, so repairs blend neatly into the surrounding surface.

Brilliant Aussie deal

Been buying Poly gear for years and this is one of their better ones. The Poly Expanding quality is excellent — everything was included and setup took under 10 minutes. Had it at the door in Brisbane within 2 days. My son immediately claimed it for himself so I had to order another. 10 out of 10.
