How to use Big Hole Smooth Finish Filler

Before you start

Make sure all surfaces are clean, dry and free from dust and grease.


  1. Firmly push the filler into the hole or crack. It needs to be slightly raised above the surface to make sure that the gap is completely filled.
  2. If you are filling bigger holes above 50mm, fill the hole in layers waiting for the previous one to dry before adding a new one.
  3. Before the filler dries, smooth it with a wet knife.
  4. After one to two hours, you will be able to redecorate.


There’s not much aftercare required. Use the filler whenever you notice a hole or crack developing.


Your tools can be cleaned in warm, soapy water.
