Coastal stone sculptures are particularly vulnerable to salt damage due to the corrosive effects of saltwater spray and airborne salts. To preserve these artworks, several effective strategies can be employed.

1. Protective Coatings: Applying specialized sealants or hydrophobic coatings can create a barrier against salt penetration. These coatings repel moisture and reduce salt crystallization on the surface.

2. Regular Cleaning: Frequent rinsing with fresh water helps remove salt deposits before they accumulate and cause damage. Soft brushes or low-pressure water jets are recommended to avoid abrasion.

3. Environmental Controls: Installing windbreaks or barriers can minimize direct exposure to salt-laden winds. Positioning sculptures in sheltered areas also reduces salt contact.

4. Material Selection: Using salt-resistant stone types, such as granite or basalt, can inherently reduce vulnerability to salt damage.

5. Professional Maintenance: Periodic inspections by conservation experts ensure early detection of salt-related issues, allowing timely intervention.

By combining these methods, the longevity and beauty of coastal stone sculptures can be significantly preserved.
