1. What’s natural wood filler made from?

2. Can natural wood filler be used outdoors?

Only some types are weather-resistant. Check the product label—external use usually requires overcoating with paint or varnish.

3. How long does natural wood filler take to dry?

4. Can I use natural wood filler under oil or solvent-based finishes?

Yes, but test compatibility. Some fillers may absorb finishes unevenly, especially on visible grain.
