Are concrete outdoor bar stools prone to efflorescence in humid climates?
Concrete outdoor bar stools can indeed develop efflorescence in humid climates due to moisture absorption and salt deposits. Efflorescence, a white powdery residue, occurs when water evaporates from the concrete, leaving behind soluble salts. While concrete is durable, its porous nature makes it susceptible to this issue in high-humidity environments. To minimize efflorescence, seal the stools with a high-quality concrete sealer and clean them regularly. Proper maintenance and choosing weather-resistant finishes can help preserve their appearance and longevity in humid conditions.
