How do you prevent efflorescence on concrete outdoor bar stools over time?
Efflorescence, the white powdery residue on concrete surfaces, is a common issue for outdoor bar stools. To prevent it, start by selecting high-quality, low-porosity concrete stools. Apply a penetrating concrete sealant annually to block moisture absorption, the primary cause of efflorescence. Regularly clean stools with a mild detergent and soft brush to remove dirt and salts before they crystallize. Avoid harsh chemicals that can damage the surface. For existing efflorescence, scrub with a vinegar-water solution or commercial efflorescence remover, then rinse thoroughly. Proper drainage around stools also minimizes water exposure. With consistent sealing and maintenance, your concrete stools can remain efflorescence-free for years.
