How to create a non-reflective finish on polished granite seating for public parks?
Creating a non-reflective finish on polished granite seating in public parks is essential to reduce glare and improve visual comfort for visitors. Here’s a step-by-step guide:
1. Surface Preparation: Clean the granite thoroughly to remove dirt, oils, or residues. Use a mild detergent and water, then dry the surface completely.
2. Mechanical Abrasion: Use diamond abrasives or sandblasting to create a matte texture. Start with coarse grit (e.g., 80-120) and gradually move to finer grits (e.g., 200-400) for a smooth but non-reflective finish.
3. Chemical Etching: Apply a granite etching solution (like acid-based treatments) to dull the surface. Test on a small area first to ensure desired results.
4. Sealing: Use a penetrating sealer designed for matte finishes to protect the granite from stains and weathering while maintaining its non-reflective properties.
5. Maintenance: Regularly clean with pH-neutral cleaners and reapply sealant as needed to preserve the finish.
By following these steps, you can achieve a durable, glare-free surface that enhances the functionality and aesthetics of public park seating.
