  • Solvent-based fillers: These are stronger. They work well for bigger holes. They can be harder to clean.
  • Epoxy fillers: These are very strong. They are great for deep damage. They are also waterproof.
  • Wood dust and glue: Some fillers use wood dust. This helps them match the wood color.
Factors That Improve or Reduce Quality

Not all wood fillers are made the same. Some will work better than others.

  • Good fillers are made with quality ingredients. They are designed to be tough. They resist shrinking. They blend well with wood.
  • Poor fillers might shrink a lot when they dry. They can crack. They might not hold paint or stain well. They may not last long outdoors.
User Experience and Use Cases

How you use the filler matters. Think about the job you need to do.

  • Small holes and cracks: Water-based fillers are usually fine for these. They are easy to use.
  • Deeper holes or gouges: You might need a stronger filler. Epoxy or solvent-based ones work well here.
