Here is another way to waterproof your outdoor storage box. Put plastic sheeting on the inside.

This will create a barrier between stored items and moisture.

Avoid Putting the Box Directly On the Floor

One of the most important things you can do to prolong the life of your outdoor storage box is to avoid putting it directly on the floor. This is especially true if you live in an area with high humidity or a lot of rainfall. Water can seep into the bottom of the box and cause the wood to rot, so it’s important to raise it up off the ground.

One way to do this is to put it on top of a few bricks or blocks. This will allow air to circulate underneath the box, which will help keep it dry. You can also buy special outdoor storage box stands that are designed to elevate the box and protect it from moisture.

Another option is to build a small platform out of pressure-treated lumber. This will not only elevate the box, but it will also provide extra storage space for things like gardening tools or pool toys. Just be sure to add a layer of landscaping fabric underneath the platform to help keep water from seeping in.

No matter which option you choose, be sure to check the box regularly for signs of water damage. If you see any warping or discoloration, it’s time to take action. [2]

Use an Outdoor Box Cover

One of the best ways to protect your belongings from the elements is to use an outdoor storage box cover. These covers are made from durable materials that will keep out rain, snow, and sun while still allowing you to access your things easily. Many covers come with built-in ventilation to prevent moisture buildup inside the box, and some even have locks to deter thieves.

Use an Outdoor Box Cover

When shopping for an outdoor storage box cover, be sure to measure your box first so you can find a cover that fits snugly. You’ll also want to consider the material—a heavy-duty tarp will offer the best protection from the elements but may be more difficult to remove when you need to access your things.

If you live in a particularly rainy or snowy climate, you may want to invest in a cover that’s specifically designed for your storage box and the weather conditions in your area.

Once you have your cover, be sure to secure it tightly so it doesn’t blow away in high winds. If possible, store your box in a sheltered spot to further protect it from the elements. [1]

Use an Interior Liner

If you want to be extra careful, you can line the inside of your storage box with a heavy-duty liner. This will create an extra barrier between your belongings and the weather. You can find liners made out of vinyl or other waterproof materials at most home improvement stores.

Another option is to use a garbage bag as a liner. Just be sure to use a bag that is large enough to fit inside the storage box with plenty of room to spare. If the bag is too small, it might rip and your belongings will get wet.

Once you have the liner in place, you can fill the storage box with whatever you need to store. Make sure to pack items loosely so that air can circulate and prevent mold and mildew from forming. If you are storing delicate items, like photo albums or electronics, wrap them in a waterproof material before placing them in the box.

Use an Interior Liner

When you are ready to close the lid, make sure that the liner is tucked in so that it doesn’t get caught. If the liner is too big, you can trim it down to size with a sharp knife. Once the liner is in place, you can close the lid and latch it shut. [1]

What is the Best Material for an Outdoor Box?

The best material for a storage box depends on many factors, including the climate you live in and what you plan to use the box for. However, some materials are more commonly used than others, such as plastic, metal, and wicker.

Metal and plastic outdoor storage boxes are popular choices for their lightweight durability. However, wicker is still an option if you want something classic with the added bonus of being water resistant too!

Storage boxes are used for storing items of any kind and can come in many different shapes, sizes or styles. Storage containers made of plastic are strong and can resist bad weather. Storage containers made of metal are even stronger but can rust if they’re not stored carefully.

Wicker is less expensive than other materials, but it also doesn’t look as good. You might want to consider this option before spending too much money on something that won’t last as long.

Metal storage boxes are a great option for those who live in areas with extreme weather conditions such as hurricanes. They are durable and can withstand most blows, so you can store your belongings inside them without any problems.[2]
