What are the effects of prolonged shade on algae growth for concrete benches?

Prolonged shade significantly influences algae growth on concrete benches, often accelerating colonization due to reduced sunlight and increased moisture retention. Shaded environments create ideal conditions for algae, as they thrive in damp, low-light areas. This can lead to slippery surfaces, aesthetic degradation, and potential structural damage over time. Regular cleaning and protective sealants are recommended to mitigate these effects. Understanding these factors helps in maintaining durable and safe outdoor furniture.
