What techniques prevent efflorescence on concrete sculpture surfaces?
Efflorescence, the white powdery residue on concrete surfaces, can mar the appearance of sculptures. To prevent it, follow these techniques:
1. Use Low-Alkali Cement: Opt for cement with low alkali content to minimize salt migration.
2. Proper Curing: Ensure adequate curing time to reduce moisture movement.
3. Waterproofing Sealers: Apply penetrating sealers to block water absorption.
4. Additives: Mix in pozzolanic materials to reduce efflorescence-causing compounds.
5. Regular Cleaning: Remove surface salts promptly to prevent buildup.
By implementing these methods, you can maintain the aesthetic quality of your concrete sculptures.
