What are the best methods to prevent efflorescence on concrete outdoor loungers?
Efflorescence, the white, powdery residue on concrete surfaces, is a common issue for outdoor loungers. To prevent it, start by using high-quality, low-alkali concrete mixes. Proper curing is essential—keep the concrete moist for at least 7 days to reduce salt migration. Applying a penetrating sealer creates a barrier against moisture, the primary cause of efflorescence. Regular cleaning with a mild acid solution (like vinegar) can remove existing deposits. For long-term protection, choose sealers specifically designed for outdoor concrete furniture. Elevating loungers slightly improves drainage, minimizing water exposure. With these steps, your concrete loungers will stay pristine for years.
