Understanding Cast Aluminum

Before we dive into the protection methods, it's important to understand what cast aluminum is and why it's a popular choice for outdoor furniture. Cast aluminum is made by pouring molten aluminum into a mold, which gives it a solid, durable structure. It's resistant to rust, corrosion, and fading, making it ideal for outdoor use. However, that doesn't mean it's completely immune to the elements. Exposure to harsh weather conditions can still cause damage, such as pitting, cracking, or discoloration.

Regular Cleaning

One of the simplest and most effective ways to protect your cast aluminum dining set is to keep it clean. Dirt, debris, and other contaminants can trap moisture against the surface of the metal, which can lead to corrosion. To clean your set, start by removing any loose dirt or debris with a soft brush or a dry cloth. Then, mix a mild detergent with warm water and use a sponge or a soft cloth to gently scrub the surface of the furniture. Rinse thoroughly with clean water and dry with a soft towel.

Avoid using abrasive cleaners, steel wool, or other harsh materials, as these can scratch the surface of the aluminum and make it more susceptible to damage. Also, be sure to dry the furniture completely after cleaning to prevent water spots and rust.

Applying a Protective Coating

Another way to protect your cast aluminum dining set is to apply a protective coating. There are several types of coatings available, including paint, powder coating, and clear sealants. Each type of coating has its own advantages and disadvantages, so it's important to choose the one that's right for your needs.

  • Paint: Painting your cast aluminum dining set can give it a fresh, new look and provide an extra layer of protection against the elements. However, paint can chip, peel, or fade over time, especially if it's exposed to direct sunlight or harsh weather conditions. To paint your set, start by cleaning the surface thoroughly and sanding it lightly to create a rough surface for the paint to adhere to. Then, apply a primer and let it dry completely. Finally, apply two or three coats of paint, allowing each coat to dry completely before applying the next one.
  • Powder Coating: Powder coating is a popular choice for outdoor furniture because it's durable, long-lasting, and resistant to chipping, peeling, and fading. Powder coating involves applying a dry powder to the surface of the metal and then baking it in an oven to create a hard, protective finish. To powder coat your set, you'll need to take it to a professional powder coating shop. The process can be expensive, but it's worth it if you want a high-quality, long-lasting finish.
  • Clear Sealants: Clear sealants are a great option if you want to protect your cast aluminum dining set without changing its appearance. Clear sealants can provide a protective barrier against moisture, UV rays, and other environmental factors. To apply a clear sealant, start by cleaning the surface of the furniture thoroughly and letting it dry completely. Then, apply the sealant according to the manufacturer's instructions, using a brush, a roller, or a spray gun. Let the sealant dry completely before using the furniture.

Covering Your Set

Covering your cast aluminum dining set when it's not in use is another effective way to protect it from the elements. A good quality cover can provide a barrier against rain, snow, UV rays, and other environmental factors. When choosing a cover, look for one that's made from a durable, waterproof material and that fits your set snugly. Make sure the cover has vents to allow air to circulate and prevent moisture from building up inside.

To cover your set, start by cleaning and drying it thoroughly. Then, place the cover over the furniture and secure it with straps or ties. Make sure the cover is tight and doesn't flap in the wind, as this can cause damage to the furniture.

Storing Your Set

If you live in an area with harsh winters or extreme weather conditions, you may want to consider storing your cast aluminum dining set indoors during the off-season. Storing your set indoors can protect it from snow, ice, and other environmental factors that can cause damage.

To store your set, start by cleaning and drying it thoroughly. Then, disassemble the furniture if possible and stack the pieces in a dry, cool place. You can use a storage shed, a garage, or a basement to store your set. Make sure the storage area is well-ventilated and free from moisture.

Avoiding Direct Contact with Moisture

Moisture is one of the biggest enemies of cast aluminum furniture. To protect your set from moisture, avoid placing it in areas where it's likely to get wet, such as near a pool, a sprinkler system, or a drainage area. If your set does get wet, dry it immediately with a soft towel to prevent water spots and rust.

Also, be careful when using your set during rainy or humid weather. If it's raining, cover the furniture with a waterproof cover or move it indoors. If it's humid, try to keep the furniture in a well-ventilated area to prevent moisture from building up.

Protecting Your Set from UV Rays

UV rays from the sun can cause damage to your cast aluminum dining set over time. UV rays can fade the color of the furniture, weaken the metal, and cause it to become brittle. To protect your set from UV rays, avoid placing it in direct sunlight for long periods of time. If possible, place the furniture in a shaded area or use an umbrella or a canopy to provide shade.

You can also apply a UV protectant to the surface of the furniture to help prevent damage from UV rays. There are several types of UV protectants available, including sprays, wipes, and creams. Choose a UV protectant that's specifically designed for use on cast aluminum furniture and follow the manufacturer's instructions carefully.

Conclusion

Protecting your cast aluminum dining set from the elements is essential if you want to keep it looking great for years to come. By following these tips and tricks, you can help prevent damage from moisture, UV rays, and other environmental factors. Remember to clean your set regularly, apply a protective coating, cover it when it's not in use, store it indoors during the off-season, avoid direct contact with moisture, and protect it from UV rays.
