What Is a Paper Mache?
This hands-on activity is perfect for kids since it doesn’t require any fancy materials or tools. And, best of all, it’s inexpensive! You probably have most of what you need around the house already.
All you really need to get started is some strips of paper and glue or paste. Once you have your basic supplies, you can get creative with adding other embellishments like paint, glitter, and feathers.
One important thing to keep in mind is that paper mache is not waterproof. That’s why it’s important to choose the right type of glue or paste and to apply a sealant if you plan on using your project outdoors or in a place where it might get wet. [1]
Why Should You Waterproof a Paper Mache?
Paper mache is a fun and easy way to create art and crafts, but if you don’t waterproof it, your project can be ruined by rain or moisture. Waterproofing paper mache will protect it from the elements and make it last longer.
There are a few different ways that you can waterproof paper mache. You can use a clear sealer, like polyurethane or mod podge. You can also use gesso, which is a white primer that you can find at most craft stores.
How to Waterproof a Paper Mache?
1. Use Waterproof Glue
If you are looking for a quick and easy way to waterproof your paper mache, then using waterproof glue is the way to go. There are a few different types of waterproof glues on the market, so make sure to choose one that is specifically designed for paper mache.
2. Use Mod Podge
Mod Podge is a popular crafting glue that can also be used to waterproof paper mache. Simply brush a layer of Mod Podge onto your project, and allow it to dry. Once it’s dry, your paper mache will be protected from the elements.
3. Seal It with Lacquer
If you want to give your paper mache project a shiny, protective coating, then sealing it with lacquer is the way to go. Lacquer is a common product found at most hardware stores and isn’t complicated to use. Follow the directions on the can carefully, and take precautions by wearing gloves and a mask while you work. Inhaling lacquer fumes can be dangerous. [2]
4. Use Wax
Wax is another great option for waterproofing paper mache. Simply melt some wax and brush it onto your project. The wax will create a protective barrier that will keep water out.
5. Cover It with Fabric
If you want to add an extra layer of protection to your paper mache, then covering it with fabric is a good option. Simply glue or sew the fabric onto your project, and you’ll create a water-resistant barrier.
6. Paint It
Paint can also be used to waterproof paper mache. Simply choose a waterproof paint, and apply it to your project. You can even use multiple coats of paint for added protection.
7. Use Resin
If you want to give your paper mache a clear, protective coating, then using resin is the way to go. Although it is slightly more complicated to use resin, it is definitely worth putting in the extra work. Please take care to follow the directions on the packaging of your resin product, as well as wear gloves and a mask while you work. Inhaling resin fumes can be dangerous. [3]
8. Seal It with Polyurethane
If you want to give your paper mache project a glossy, protective coating, then sealing it with polyurethane is the way to go. Polyurethane is a type of coating that can be found at most hardware stores. It’s easy to apply and relatively inexpensive. Just make sure to follow the directions on the can, and wear gloves and a mask while you work, as polyurethane can be harmful if inhaled.
9. Use Shellac
Adding shellac to your paper mache project will give it a high-gloss finish. Though Shellac may take a bit more effort to work with than some of the other options on this list, it is definitely worth your time. Just make sure to follow the directions on the shellac carefully, and wear gloves and a mask while you work, as shellac can be harmful if inhaled. [4]
10. Use Enamel Paint
If you want to give your paper mache project a durable, protective coating, then using enamel paint is the way to go. Enamel paint can be found at most hardware stores, and it’s relatively easy to apply. Just make sure to follow the directions on the can, and wear gloves and a mask while you work, as enamel paint can be harmful if inhaled. [4]

Useful Tips for Making a Paper Mache Waterproof
If you are planning to make a paper mache project that will be exposed to the elements, it is important to waterproof it. Here are some useful tips to help you make your paper mache waterproof:
- Choose the right type of paper. Use either waxed paper or coated Kraft paper for your project. This type of paper is more resistant to water and will not expand or contract as much as regular paper when it gets wet;
- Apply several layers of newspaper strips. The more layers you apply, the better protected your project will be from moisture;
- Use a waterproof sealer. Once you have applied the desired number of layers, seal the entire project with a waterproof sealer. This will add an extra layer of protection against moisture;
- Let the project dry completely before using it. It is important to let the sealer dry completely before exposing your project to the elements. Otherwise, the moisture could cause the paper mache to swell and potentially ruin your project;
By following these tips, you can be sure that your paper mache project will be resistant to moisture and will last for many years to come. [5]
