Before I learned about the usage of cardboards, I always thought they are useless material or can only be used for packaging purposes. So, whenever I moved from one place to another or bought some new items, I gathered the cardboards and sold them at a certain period of time. But once I thought, why not use them rather than just throwing them or selling them out. I also searched like you and gathered some wonderful ideas about using these items. For this article, particularly, I have chosen to show you how to make cardboard hard like wood.

How to Make Cardboard Hard Like Wood
First of all, you have to apply a glue coat on the surface of the cardboard. So, follow the steps below for doing that accurately.
Take the PVA glue and mix it’s one part with one part of water. Now, choose your work area and spread a newspaper around it.
Place the cardboard on the newspaper that you have placed earlier and then start applying the mixture to the cardboard surface. Once you complete this process, let the cardboard dry properly. Leave it for two hours at least; it will become dry within that time.
If the first layer has dried out, you have to now apply the second layer on the cardboard’s surface. Don’t hurry while you apply this coat on the cardboard surface; take your time, and do it thoroughly. Make sure to apply the coat to the underside and inside of your cardboard. Once you complete applying the PVC glue, leave it dry again.
Now, you have to mix the glue again, but the ratio of glue and water will change now. In this step, you have to take two parts of the glue and mix it into one part of the water.
Next, you have to apply the third coat with this more PVC mixture. Like always, when you will complete, you have to give the required time to dry properly. While doing this, you will notice that your cardboard is taking a shiny plastic-like appearance. That’s the sign; you are heading towards the right place.
After that, you have to create another mixture of PVC glue. Don’t get annoyed; it is all about the game of glue. The more glue you will apply, the harder your cardboard will become. But you have to maintain consistency; otherwise, the entire project can get ruin. You have to focus on the bottom and interior parts of your cardboard when you are applying the fourth layer of PVC.
This is time to end up the process. I mean, you have to apply the final coat of PVC glue. Make another mixture of glue by maintaining the ratio of 2:1 and then apply all of them on the surface of the project. When this final coat dries, your cardboard will become harder than before.
Okay, now you have to focus on applying a fiberglass resin coat. So, let’s see how you will do that.
For this purpose, you have to choose your workspace in a well-ventilated area. Like the previous method, spread a newspaper on the floor so that your floor doesn’t get damaged during the process. After that, place the silicone mat and place your cardboard on that mat. As the cardboard has become hardened, it won’t stick with the silicone mat. By the way, make sure to wear safety glasses and gloves during this process.
Now, take the polyester resin and mix it up with the catalyst. The amount of this mixture depends on your cardboard’s size, so use your eyeballs to ensure the perfect amount. Allow 17 minutes to set resin properly. I will recommend you to mix a little amount at the initial stage and then mix more if needed.
Once you have finished mixing the resin, take a brush, and start applying the resin to your cardboard’s surface. In this case, you may have to accomplish the process in two parts because you won’t be able to apply the mixture on both sides at the same time. So, finish the front side first and then start working with the bottom side. Make sure to apply enough resin so that no space remains empty.
After applying the resin on the entire surface, you have to leave it for 24 hours to let it set properly. Once it is dry, you have to apply another layer of resin on the surface and then leave it for another 24 hours drying process. That’s it; your cardboards will now become hard as woods.
Frequently Asked Questions
Can cardboard with dirt on it be recycled?
Yes, cardboard with dirt on it can be recycled.
However, you need to clean the cardboard and make sure that there is no paint or other chemicals on it before recycling.
You can either recycle the cardboard yourself by taking it to a local recycling center, or you can take it to your city's recycling depot, where they will recycle it for you.
Is it better to compost or recycle cardboard?
Composting is the best option for cardboard because it will break down the materials into smaller pieces that are easier to digest.
Recycling is better than composting when it comes to paper, glass, metal, and plastic. However, recycling won't help in breaking down cardboard material.
What happens when cardboard gets wet?
When cardboard gets wet, it can absorb water and swell. This is because cardboard has a high level of cellulose which acts like a sponge. The swelling causes the paper to tear easily, and then the ink on it will start to run.
Can you turn cardboard into wood?
Yes, you can make wood from cardboard. There are many ways to do this, but the simplest is to use the pressure cooker method.
Place a sheet of cardboard in the bottom of a pressure cooker and then add water until it's saturated. Cook on high for about 10 minutes or until all the water has evaporated and turned into steam.
You will need to keep adding more water so that there is always enough liquid in the pot. The steam will turn into hot liquid, which will cause fibers from the cardboard to split apart, creating long thin strips of wood fiber with each pass through the boiler.
Hopefully, the above process is going to be way more helpful for you, and you won’t have to ask anyone how to make cardboard hard like wood. If you are still confused or got something more enhanced, let me know through the comment section.
