How does natural rattan’s porosity affect its absorption of rainwater?
Natural rattan’s porous structure plays a significant role in its interaction with rainwater. Due to its high porosity, rattan fibers can absorb moisture quickly, which may lead to swelling, warping, or even mold growth if not properly treated. This absorption property makes rattan furniture susceptible to damage when exposed to prolonged rain or high humidity. However, this same porosity also allows rattan to dry relatively fast if placed in a well-ventilated area. To enhance durability, many manufacturers apply protective coatings or sealants to reduce water absorption. Understanding rattan’s porosity helps in maintaining its longevity, especially for outdoor furniture. Proper care, such as avoiding direct rain exposure and regular cleaning, can minimize moisture-related issues.
