Fortunately, waterproofing paper mache is a simple and inexpensive process. Our comprehensive guide discusses various waterproofing methods, ensuring the longevity and integrity of your creations.
This article explains how to waterproof paper mache effectively using different methods, including a waterproof sealant, polyurethane, or wax.
Each method has advantages and disadvantages, so knowing what you want from your paper mache project is important before deciding which method is best for you.
So if you’re tired of having your paper mache creations ruined by water damage, read on to find out how to make them waterproof.
8 Amazing Ways on How to Waterproof Paper Mache
1. Using Waterproof Spray
Waterproof sprays, such as those used in the automotive industry, can be applied to the paper mache object to create a protective layer.
This is especially useful to protect your project from water exposure or outdoor elements. If your project is done with newspaper, it’s best to use a light spray so the paper underneath doesn’t become brittle.
2. Using Resin
Casting resin can waterproof paper mache projects, particularly if you want an airtight seal. This method is highly effective and creates a durable protective layer.
The downside is that it can be difficult to use and is more expensive than other methods.
3. Using Polyurethane
Polyurethane sealants are great for waterproofing paper mache projects. They create an invisible protective coating that protects your project from water damage.
This method is fairly inexpensive, but it’s important to ensure you apply the sealant properly, or it won’t be effective.
4. Using Wax
Waxing paper mache can protect the project from moisture and make it more durable.
This method is inexpensive but will require maintenance as the wax must be reapplied over time. If your project is exposed to a lot of water, there may be better methods for you.
5. Using Mod Podge
Mod Podge is a great way to seal and protect paper mache objects. It’s easy to use, inexpensive, and creates a glossy finish that can make your project look more professional.
However, it won’t provide as much waterproofing power as other methods. When using mod podge, do some light sanding on the object before you begin. This will help smooth out any imperfections and give you a better result.
6. Using Lacquer
Lacquer is an effective waterproofing solution that will create a hard, protective coating on paper mache objects.
It’s easy to apply but can be quite expensive and requires more skill than other methods. However, if applied correctly, it can create a long-lasting waterproof barrier.
7. Using Melted Wax
Melted wax is a great way to waterproof paper mache objects. It’s easy to use and requires no special tools or supplies. Simply melt some beeswax in a double boiler and then brush it on the paper mache object.
This will create a barrier protecting the project from moisture and water. Allow the wax to cool and harden before fully displaying it.
Test a small area first to be sure the wax won’t discolor the paper mache object.
8. Sealing with Waterproof Glue
Waterproof glue, also known as polyurethane glue, can be used to seal paper mache projects. This will create a strong and durable waterproof barrier that will protect the object from moisture and water damage.
Make sure to use a good quality waterproof glue or it won’t provide adequate protection. Additionally, make sure to follow the manufacturer’s instructions for best results.
With these 8 methods, you can waterproof paper mache items and make them last longer. Choose the best method for you and enjoy many years of fun creations!

Additional Tips to Waterproof Paper Mache for Outdoor Use:
1. If your project is used outdoors, use a waterproof spray specifically designed for outdoor use. This will create a stronger barrier than indoor-specific sprays.
2. Make sure the paper mache object has no cracks or holes before you begin the waterproofing process. These can weaken the protective layer and cause water damage.
3. If you are using melted wax, mix paraffin and beeswax for the best results.
4. Always test your waterproofing method on a small area of the paper mache project before continuing with the entire piece. This will help ensure that the waterproofing process won’t affect the color or texture.
5. If waterproofing for outdoor use, let the paper mache project dry and cure completely before exposing it to the elements. This will help ensure the best results.
6. Test the waterproofing regularly after exposure to ensure it is still effective.
7. Be sure to use a high-quality sealant for outdoor use when using paints or varnishes in your project. This will help ensure that the paint won’t be affected by water damage.
With these tips and methods, you can now confidently waterproof paper mache projects! Enjoy crafting your favorite pieces with longer-lasting protection.
