How to use Expanding Foam Filler

Before you start

  1. Open doors and windows for added ventilation.
  2. Ensure the surface and hole is clean and free of grease and loose material.
  3. Cover furniture, carpets and surrounding areas and mask off any brickwork.

Never use tools on the valve and avoid bending it as this might cause accidental product release.


  1. Shake the can well for at least 30 seconds.
  2. Carefully screw the nozzle onto the valve.
  3. Moisten the surface with water.
  4. Hold the can upside down and start filling from the lowest point, shaking the can occasionally during use.
  5. Only fill half of the gap that needs filling – the foam will expand and take care of the rest.
  6. Once it’s dry, it can be easily cut, sanded, plastered or painted.


If the foam is going to be exposed to sunlight, it must be coated/painted over.           


Any spills or overflow and be cleaned up with nail polish remover.
