What techniques prevent efflorescence on concrete figurative sculptures?

Efflorescence, the white powdery residue on concrete sculptures, is a common issue caused by moisture and salt migration. To prevent it, follow these techniques:

1. Use High-Quality Concrete Mix: Opt for low-alkali cement and additives to minimize salt content.

2. Proper Curing: Ensure slow, even curing to reduce internal moisture and cracking.

3. Apply Sealants: Use penetrating or film-forming sealants to block moisture absorption.

4. Control Moisture Exposure: Avoid placing sculptures in damp areas or direct water contact.

5. Regular Cleaning: Gently wash sculptures to remove salt buildup before it hardens.

By implementing these methods, you can maintain the beauty and longevity of your concrete figurative sculptures.
