How do stone sculptures resist corrosion from de-icing salts in winter?

Stone sculptures face significant challenges during winter, especially when exposed to de-icing salts used on roads and walkways. These salts can accelerate corrosion and weathering, but several methods help protect stone artworks.

1. Material Selection: Dense, non-porous stones like granite or marble are naturally more resistant to salt penetration compared to softer stones like limestone.

2. Protective Sealants: Applying water-repellent sealants creates a barrier, preventing salt and moisture from seeping into the stone.

3. Regular Cleaning: Prompt removal of salt residues with gentle washing reduces long-term damage.

4. Proper Placement: Elevating sculptures or placing them away from high-salt areas minimizes direct exposure.

5. Seasonal Maintenance: Inspecting and reapplying protective coatings before winter ensures ongoing defense.

By combining these strategies, stone sculptures can endure harsh winter conditions and retain their beauty for years.
