What are the best methods to seal knots in pine outdoor ottomans?

Sealing knots in pine outdoor ottomans is essential to prevent moisture absorption, cracking, and resin leakage. Here are the best methods to ensure long-lasting protection:

1. Sand the Surface: Start by sanding the knots and surrounding area with 120-grit sandpaper to create a smooth surface for better adhesion.

2. Use Shellac or Knotting Solution: Apply a shellac-based knotting solution or specialized wood primer to seal the knots and prevent resin bleed.

3. Epoxy Resin Filler: For larger or loose knots, fill them with epoxy resin to stabilize the wood and create a waterproof barrier.

4. Waterproof Sealant: Finish with a high-quality outdoor wood sealant or spar urethane to protect the entire ottoman from UV rays and moisture.

5. Regular Maintenance: Reapply sealant every 1-2 years to maintain protection against weathering.

By following these steps, your pine outdoor ottoman will stay durable and resistant to the elements for years to come.
