How to use Exterior Multi Purpose Smooth Finish Filler

Before you start

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


  1. Push the filler firmly into the hole or crack. Overfill it to ensure it’s slightly raised above the surface. This will make sure that the hole is definitely filled.
  2. Before it full dries, smooth it with a wet knife.
  3. Wait one to two hours for the filler to dry.
  4. If the hole you are filling is deeper than 20mm, you will need to fill it with several layers. Wait one to two hours for each layer to dry before adding another.


Once the filler has completely dried, you’ll be able to decorate over it.


Your tools can be easily cleaned in warm, soapy water.
