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.
