For a flawless finish on your wood projects, restorations or repairs, we offer some helpful tips that will make your life easier.





Thin too thick wood filler

Over time and when left exposed to air the wood filler will start to thicken and eventually harden. Before it starts to harden, add a small amount of warm water and stir to thin the wood filler for use. Always ensure the product package is closed when not in use to prevent hardening.


Use a palette or putty knife to apply

As mentioned in the video above, use a palette knife or putty knife to apply the wood filler correctly and ensure that it completely fills any holes.


Allow wood filler to dry in shade

To ensure that the product cures and hardens as it should, do not place it in sunlight or a heat source as this will force the product to cure too quickly and could result in shrinkage or cracking.


A dab of glue keeps wood filler 'vas'

One thing I learned during my DIY days was to apply a small dab of glue to the top of screws before filling the hole with wood filler. Even if there was shrinkage, the wood filler remained in the hole and I could apply more filler to the gaps.


Choose the correct colour

When purchasing wood filler for a project remember that the colour of the wood filler should match the finished colour of the project. In other words, if you are going to be staining the wood a particular colour, select a wood filler with a tint that matches that colour. The reason for this is that the wood filler does not take wood stain and any areas filled will be visible.
