How does prolonged exposure to rain affect polypropylene bar stool integrity?

Polypropylene bar stools are popular for outdoor use due to their lightweight and cost-effective nature. However, prolonged exposure to rain can compromise their structural integrity over time. Polypropylene is a type of plastic that resists moisture absorption, but constant wet conditions may lead to surface degradation, fading, and even warping. UV rays combined with rainwater can accelerate this process, causing the material to become brittle and prone to cracking.

To mitigate damage, consider applying a UV-resistant sealant or storing stools indoors during heavy rainfall. Regular cleaning and maintenance can also extend their lifespan. While polypropylene is more weather-resistant than many other plastics, no material is entirely immune to long-term environmental stress. Choosing high-quality, UV-stabilized polypropylene stools can help ensure better durability in wet climates.
