Can freeze-thaw cycles cause spalling in concrete outdoor armchairs?

Freeze-thaw cycles can indeed cause spalling in concrete outdoor armchairs, leading to surface deterioration and structural weakening over time. When water penetrates the porous concrete and freezes, it expands, creating internal pressure that cracks the material. Repeated cycles exacerbate this damage, causing flakes or chunks to break off—a process known as spalling.

To mitigate this, use high-quality, air-entrained concrete designed for outdoor use, which contains tiny air pockets to absorb expansion. Sealing the surface with a waterproof coating can also reduce water absorption. Regular maintenance, such as inspecting for cracks and reapplying sealant, helps prolong the chair's lifespan. Choosing weather-resistant materials or storing armchairs indoors during harsh winters can further prevent freeze-thaw damage.

By understanding these risks and taking preventive measures, you can ensure your concrete outdoor furniture remains durable and visually appealing for years.
