How to create a non-reflective surface on polished granite outdoor chairs?

Polished granite outdoor chairs can be stylish but often suffer from excessive glare, making them uncomfortable in bright sunlight. To create a non-reflective surface, consider these methods:

1. Matte Sealants: Apply a matte-finish sealant designed for stone surfaces. This reduces shine while protecting the granite from weathering.

2. Acid Etching: Use a mild acid solution (like diluted vinegar or commercial stone etcher) to lightly etch the surface, creating a subtle texture that diffuses light.

3. Sandblasting: For a more permanent solution, sandblasting with fine grit can create a uniformly matte surface. Professional equipment is recommended.

4. Anti-Glare Coatings: Specialty coatings (e.g., UV-resistant matte varnishes) can dull reflections without compromising durability.

5. Textured Pads or Brushes: Manually scuffing the surface with abrasive pads (e.g., diamond-coated) can break up the polish.

Always test methods in an inconspicuous area first. Regular maintenance (cleaning with pH-neutral products) will preserve the non-reflective effect. These techniques balance aesthetics and functionality for outdoor granite furniture.
