What are the effects of prolonged water immersion on plastic outdoor rectangular tables?

Prolonged water immersion can significantly impact the durability and appearance of plastic outdoor rectangular tables. Continuous exposure to water may lead to material degradation, including warping, discoloration, and weakening of structural integrity. Over time, moisture can cause mold or mildew growth, especially in crevices or joints. Low-quality plastics may become brittle or develop cracks, while UV exposure combined with water can accelerate fading. To minimize damage, choose UV-resistant, high-density polyethylene (HDPE) tables, ensure proper drainage, and store tables during heavy rains. Regular cleaning and protective covers can also extend their lifespan.
