Whether you can leave your outdoor furniture in the rain depends heavily on the material it's made from. Understanding your furniture's construction is key to knowing if it needs protection from the elements.
Some materials are built to withstand rain and moisture, while others will quickly deteriorate if left exposed. Here’s a breakdown of common outdoor furniture materials and their relationship with rain.
Materials That Can Handle Rain:
* Aluminum: Especially powder-coated or cast aluminum, is highly rust-resistant and can be left in the rain without issue.
* Teak: This dense wood contains natural oils that make it exceptionally weather-resistant. It will weather to a silvery-gray patina but remains structurally sound.
* Resin Wicker: Synthetic wicker, made from polyethylene (PE) resin, is waterproof and will not be damaged by rain. Ensure the underlying frame is also rust-proof.
* Plastic/Resin: Most all-weather plastics and resins are designed to be left outdoors year-round and are impervious to water damage.
Materials That Need Protection:
* Steel: Unless it is specifically labeled as stainless or galvanized steel, it is prone to rust and must be covered or stored during rain.
* Wrought Iron: While durable, it can rust if its protective finish is scratched or worn. It's best to cover it.
* Natural Wood (like Pine or Acacia): Untreated or poorly sealed wood can rot, warp, and crack when exposed to constant moisture.
* Fabric: Most cushions and umbrellas are not fully waterproof but are water-resistant. They will dry faster if made with quick-dry foam, but covering them prolongs their life.
Best Practices for Rainy Weather:
1. Use Furniture Covers: High-quality, breathable covers are the best defense for furniture that shouldn't get wet. They protect from rain, sun, and debris.
2. Check Drainage Holes: Many chairs and tables have small drainage holes to prevent water from pooling. Ensure these are not blocked.
3. Store Cushions: For the longest lifespan, store cushions in a dry place when not in use, especially during prolonged wet weather.
4. Regular Cleaning: Periodically clean your furniture to remove dirt, pollen, and moisture that can lead to mold or mildew.
In conclusion, you can leave rain-resistant materials like aluminum, teak, and resin wicker in the rain. However, for furniture made from steel, wrought iron, or most natural woods, using a cover is highly recommended to prevent damage and extend its longevity.
