How to use Super Flexible Smooth Finish Filler

Before you start

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


  1. Push the filler firmly into the hole or crack. Leave it slightly raised above the wood to make sure the crack or hole is filled.
  2. Before the filler has dried, smooth over with a wet knife.
  3. After one hour, it will be dry and can be painted over.

If you are filling a wider hole, fill it in 6mm layers leaving one hour between each layer



Tools can be cleaned in warm, soapy water.
