Buying Guide
Choosing the right wood filler can seem daunting, but here are a few factors to consider:
- Type of Repair: Are you filling small nail holes or repairing a large, damaged area? For small imperfections, a basic wood filler like Elmer’s might suffice. For larger repairs, consider a more robust option like Bondo.
- Interior vs. Exterior: If the repair is outdoors, you’ll need a filler specifically designed for exterior use, like DAP Plastic Wood-X.
- Staining or Painting: If you plan to stain the wood, choose a stainable wood filler like Minwax. If you’re painting, most fillers will work, but make sure they are paintable.
- Color Matching: Some fillers come in various colors or can be tinted. Consider this if you want the repair to blend seamlessly with the surrounding wood. Goodfilla offers great tinting options.
- Ease of Use: Consider your skill level. Some fillers, like Bondo, require mixing and have a strong odor, while others, like Elmer’s, are ready to use and easy to clean up.
- Durability: Think about the amount of wear and tear the repaired area will be exposed to. High-traffic areas may require a more durable filler.
FAQs
Q: How do I apply wood filler?
A: First, clean the area you want to fill. Use a putty knife to apply the filler, pressing it firmly into the gap or hole. Overfill slightly to allow for sanding. Let it dry completely according to the manufacturer’s instructions, then sand smooth.
Q: Can I stain wood filler?
A: Yes, but only if you use a stainable wood filler like Minwax Stainable Wood Filler. Regular wood fillers may not accept stain evenly.
Q: How long does wood filler take to dry?

A: Yes, you can use wood filler on engineered hardwood. Just make sure to choose a filler that is compatible with the finish and color of your floor.
