How to prevent efflorescence on concrete outdoor seating exposed to moisture?
Efflorescence, the white powdery residue on concrete surfaces, is a common issue for outdoor seating exposed to moisture. To prevent it, follow these steps:
1. Use Quality Concrete Mix: Opt for low-alkali cement and additives to reduce efflorescence-causing salts.
2. Proper Sealing: Apply a penetrating sealer to block moisture absorption and salt migration.
3. Ensure Good Drainage: Slope the seating area to prevent water pooling.
4. Regular Cleaning: Remove dirt and debris to minimize moisture retention.
5. Avoid De-Icing Salts: These can introduce salts that contribute to efflorescence.
By addressing moisture exposure and sealing the concrete properly, you can maintain a clean, efflorescence-free outdoor seating area.
