Seeing your plastic outdoor furniture become brittle and develop cracks can be frustrating. This common issue is primarily caused by prolonged exposure to the sun's UV rays, extreme temperature changes, and inadequate maintenance. Fortunately, you can prevent this damage and extend the life of your furniture with some simple, proactive steps.
The most significant threat to plastic furniture is ultraviolet radiation from the sun. Over time, UV rays break down the polymer chains in the plastic, causing it to lose its flexibility and strength, leading to brittleness and cracks. To combat this, your first line of defense is to apply a UV-protectant spray specifically designed for plastic furniture. These sprays create a protective barrier that shields the plastic from the sun's harmful rays. Reapply this protectant every few months, especially during the peak summer season, for consistent coverage.
Where you place your furniture also plays a crucial role. Whenever possible, position chairs and tables in shaded areas, such as under a patio umbrella, a pergola, or a large tree. If you have storage space, the ultimate protection is to bring furniture indoors or into a shed during the harsh winter months or when you know it won't be used for an extended period. For times when storage isn't an option, invest in high-quality, breathable furniture covers. Avoid plastic tarps, as they can trap moisture underneath, leading to mold and mildew.
Your cleaning routine is another critical factor. Avoid using harsh chemicals, abrasive scrubbers, or power washers on a high setting, as these can scratch and weaken the plastic's surface. Instead, create a gentle cleaning solution of mild dish soap and warm water. Use a soft-bristled brush or a cloth to clean the furniture, and always rinse thoroughly. This regular cleaning removes dirt and pollutants that can accelerate the degradation process.
Finally, be mindful of the physical stress you place on the furniture. Avoid dragging chairs and tables across the patio, as this can create stress points that are prone to cracking. Instead, always lift items to move them. By integrating these practices—using UV protectants, providing shade and cover, gentle cleaning, and careful handling—you can significantly slow down the aging process of your plastic outdoor furniture, keeping it looking great and functional for many seasons to come.
