Different Materials of Boxes
There are many reasons why you might want to waterproof a box.

It could be even because you want to assure your belongings will be transported safely. No matter what your reason is, learning how to make a waterproof box is a handy skill to have.
There are many types of materials that can be used to make a waterproof box. The most popular are made out of plastic, metal, or wood.
Plastic boxes are lightweight and inexpensive but they may not be as strong as other materials. Metal boxes are more durable but can be heavier than plastic or wooden boxes. Wooden boxes are the most expensive option but they are also the strongest and most durable option.
Cardboard boxes should not be used to store or transport water-sensitive items but if you have the need for it, you can waterproof them as well, although it won’t be nearly as effective as for other types of boxes. [1]
Can You Make Any Box Waterproof?
It is possible to make any type of box waterproof. However, the level of water resistance may vary depending on the material used. A wooden box is a perfect choice for garden work, as it is strong and robust but will not stand up to soaking and remain watertight. Hence waterproofing is important. Let’s look at some of the most common methods to waterproof your box.
Making a Waterproof Wooden Box
First, you need to decide on the size of the box. The sides of the box should be at least an inch thick to provide enough strength and durability. When it comes to dimensions, it’s all up to your needs.
Once you have decided on the sizes of the box, use a saw to cut the pieces out of lumber. You can use any type of wood for your future box.
After cutting the pieces of wood, sand the edges of each one until they are smooth. This will help to prevent any injuries down the road and will help the sealant to adhere better.
The next step is attaching the pieces together with waterproof glue or silicone caulk. You need to attach the longer walls to the shorter walls. Make sure the pieces are aligned correctly before gluing them together and leave the box to dry. The drying time depends on a lot of factors and sometimes can take up to 24 hours.
After the walls have been glued together, it’s time to secure them even further with braces and some screws. Use the brace for each corner of your box and screw it into place. This will ensure that the walls don’t move and that the box is completely waterproof.
Now that your box is complete, it’s time to waterproof it for good. Apply a sealant or paint to all of the boxes’ external surfaces. This will help keep the water out and your items safe and dry. One of the best sealant choices for water protection is varnish. [1], [2], [3]
Making Cardboard Box Waterproof
Yes, it is possible to make a cardboard box waterproof. It’s quite easy and doesn’t require any special materials or tools. It won’t offer 100% protection. We mind you, but it will reduce the moisture infiltration significantly.
So, let’s see how to do it!
By using a PVA glue
This method should keep the moisture away and your box waterproof for a while, but it’s not permanent. If you want to make it more durable, you can use the other methods below. [4], [5]
By using a protective coating
Another way to waterproof your cardboard box is by using a protective coating.
Avoid using polyurethane on cardboard boxes as it doesn’t work that well on cardboard surface and may even damage it.
Shellac is a to-go choice for all non-wooden surfaces. It can be applied with a brush, and it will dry quickly.
The other type of coating you can use is waterproof acrylic paint. It can be sprayed or applied with a brush, and it dries quickly as well. However, it will make your box a bit heavier, so keep that in mind.
Either of these methods should provide good results and keep your box waterproof for a longer period of time. [4], [5]
