Removing varnish from an outdoor table can restore its natural beauty and prepare it for a fresh finish. Here are some effective methods to strip old varnish safely and efficiently:

1. Sanding: Start with coarse-grit sandpaper (80-100 grit) to remove the top layer of varnish, then switch to finer grit (150-220) for a smooth surface. Always sand along the wood grain to avoid scratches.

2. Chemical Strippers: Apply a eco-friendly varnish stripper, following the manufacturer’s instructions. Scrape off the softened varnish with a putty knife, then clean the surface with mineral spirits.

3. Heat Gun: Use a heat gun to loosen the varnish, then scrape it away carefully. Avoid overheating to prevent wood damage.

4. Natural Solutions: A mixture of baking soda and vinegar can help break down varnish for eco-conscious refinishing.

After removal, clean the table thoroughly and apply a new sealant to protect it from weather damage. Choose a method based on your table’s material and your preferred level of effort!
