While it is impossible to make the actual epoxy resin at home due to a difficult manufacturing process and hard-to-get materials, it is possible to mix additives into epoxy resin to create a specialised epoxy to match any given repair need. To make epoxy wood filler suited for shaping and contouring, add colloidal silica to two-part epoxy. Alternatively, you can add sawdust to epoxy to make a wood filler that closely matches a wood's texture.
Things you need
- 2-part epoxy resin
- Colloidal silica
- Ice lolly sticks
- Paper bowls
Place one segment of the epoxy resin into one bowl, and the other segment into the other bowl. Mix the two parts of epoxy together into a third bowl using a lolly stick to stir.
Add one part of colloidal silica for every five parts of epoxy to the mixture. Stir until blended.
Use this epoxy mixture to spread onto areas that need a high amount of contouring or shaping. This epoxy is ideal to repair wood moulding, wood columns and other items with a high level of detail.
Mix the two parts of the epoxy resin together in a bowl. Stir until well blended.
Add two parts of sawdust for every five parts of epoxy. Stir the mixture together until the sawdust is completely blended into the epoxy.
Use this mixture as a filler for holes and other crack repairs. This filler also works well for wood rot repairs. The sawdust in the epoxy gives the patch a similar texture to the original material, creating a more seamless appearance.
