Outdoor stone sculptures are vulnerable to fungal growth due to exposure to moisture, shade, and organic debris. To preserve their aesthetic and structural integrity, follow these proven methods to prevent fungal infestations:

1. Regular Cleaning: Use a soft brush and mild detergent to remove dirt, algae, and organic matter. Avoid harsh chemicals that may damage the stone.

2. Proper Drainage: Ensure the sculpture’s base allows water to drain away, preventing stagnant moisture that fosters fungal growth.

3. Antifungal Treatments: Apply commercial or natural antifungal solutions (e.g., vinegar, hydrogen peroxide) to inhibit spore development.

4. Sunlight Exposure: Position sculptures in areas with adequate sunlight, as UV rays naturally deter fungal growth.

5. Sealants: Use breathable, water-repellent sealants to protect the stone without trapping moisture.

By combining these strategies, you can effectively safeguard your stone sculptures from unsightly and damaging fungal growth.
