Why aren't wooden ladders painted?

Wooden ladders are typically not painted to maintain their natural texture and grip, which can be compromised by paint. Additionally, paint can hide signs of wear and damage, making it harder to assess the ladder's safety. The natural wood allows for better adherence to surfaces when climbing, reducing the risk of slipping. Moreover, untreated wood can better absorb moisture, helping to prevent rot and prolonging the ladder's lifespan.
