This tutorial provides a DIY solution to filling holes and gaps in wooden areas by creating a homemade DIY Wood Filler. This technique can be used with both polyester and epoxy resins. Resin compatible dyes can be used to create colour matching where needed. It is notable that if you can get a piece of the same wood to create the wood flour, then the matching process will be easier. The strength of the resin is also much superior to that of traditional 1 part wood fillers and shop bought fillers.
