What are the effects of freeze-thaw cycles on concrete bench coatings?
Freeze-thaw cycles significantly impact the durability and performance of concrete bench coatings. When water penetrates the coating and freezes, it expands, causing micro-cracks and weakening the protective layer. Repeated cycles lead to peeling, flaking, and loss of adhesion, exposing the concrete to further damage. High-quality, weather-resistant coatings with flexible polymers can mitigate these effects by accommodating expansion and contraction. Proper surface preparation and sealants also enhance longevity. Understanding these impacts helps in selecting the right coatings for outdoor concrete furniture in cold climates.
