Do you have a paper sign that needs to be waterproofed? Whether it’s an outdoor sign for your business or a poster for an event, ensuring that your paper sign can withstand the elements is essential.
Waterproofing a paper sign protects it from the weather and ensures it looks its best and lasts longer.
In this article, we’ll show you how to waterproof a paper sign quickly and easily so you can keep your message looking great no matter the weather.
We’ll also give some tips to make sure your waterproof paper sign is up to the task. Read on for more information.
Why It’s Important to Waterproof Paper Sign?
Waterproofing your paper signs is important if you plan to display them outdoors. This can include storefront business signs, event posters, or any other type of sign that will be exposed to the elements.
Without waterproofing, your paper sign could damage in bad weather such as wind and rain. Water can make colors fade and writing run, making the sign look unattractive and unreadable.
Waterproofing your paper sign ensures it remains readable and professional-looking for much longer.
Materials You’ll Need:
Waterproofing a paper sign is easy with the right materials. Here’s what you’ll need:
- Clear acrylic sealant or clear polyurethane.
- Paintbrush or foam brush for applying the sealant.
- Clean cloth or paper towel.
How to Waterproof a Paper Sign: 8 Steps to Follow
Step 1: Clean the surface.
Start by wiping down the paper sign to remove any dirt or debris. Use a cloth or paper towel and be sure to get all of the corners and edges. If your sign is particularly dirty, you may need a wet rag and soapy water.
Step 2: Apply the sealant.
Next, apply a layer of clear acrylic sealant or polyurethane to the surface of your paper sign. Use a paintbrush or foam brush for best results and make sure that all sides of the sign are well-covered.
Step 3: Allow to dry.
Once you’ve applied the sealant, allow it to dry for at least 24 hours before moving on to the next step. This will allow the sealant to bond with the paper and create a waterproof layer on your sign.
If the sealant is still wet after 24 hours, wait until it’s completely dry before continuing.
Step 4: Apply a second layer.
Once the first layer has dried, apply a second layer of clear acrylic sealant or polyurethane to the paper sign. This will add extra protection and ensure that your waterproof paper sign can withstand the elements longer.
Step 5: Allow to dry again.
Once you’ve applied the second layer, allow the paper sign to dry for several hours, or overnight. This will ensure that the sealant has completely dried and bonded with the paper, creating a waterproof barrier that should keep your sign safe from water damage.
Step 6: Apply polyurethane paint.
If you want an extra layer of protection for your paper sign, consider applying polyurethane paint. This will help seal it from water damage and ensure the colors won’t fade easily.
You can use a brush or spray can to apply the paint, making sure to cover all sides of the sign evenly.
Step 7: Check for any gaps or holes.
Once you’ve applied all of the waterproofing layers, it’s important to check for any gaps or holes in the paper sign.
This can be done by running your finger along each side of the sign and feeling for any air pockets that could let water in. If you find a gap, simply apply another sealant layer to cover it.
Step 8: Allow to dry completely.
Once you’re satisfied with the waterproofing, allow your paper sign to dry completely before using it outdoors. This will ensure that all layers have had time to bond and create a watertight barrier for maximum protection.
Congratulations! You’ve now successfully waterproofed a paper sign. With these simple steps, you can keep your signs safe from the elements and look professional for much longer.

Frequently Asked Questions:
How do you waterproof a paper poster?
You can waterproof a paper poster by applying two to three coats of a sealant or varnish, such as Mod Podge. This will form an invisible barrier over the paper and protect it from moisture, making it water-resistant.
You should also apply several layers of clear tape to the poster’s edges to protect against water damage. Finally, you can also spray the poster with a waterproofing aerosol to create an extra layer of protection.
Does waterproofing paper reduce its quality?
No, the waterproofing paper does not reduce its quality or vibrancy. It may even enhance it!
Waterproofing creates an additional layer of protection for your paper poster, which can preserve its color and vibrancy over time. The sealant or varnish waterproofing the paper will not alter its appearance.
What can I use to make a waterproof sign?
Vinyl, PVC, and aluminum are the most common materials used to make a waterproof sign. Vinyl is the most cost-effective option and can be printed with special inks for an eye-catching display.
PVC is waterproof and lightweight, making it ideal for outdoor use. Aluminum signs are the strongest and most durable of these options and are often used for permanent displays.
Does laminating paper make it waterproof?
Yes, you can make paper waterproof by laminating it. Laminating adds a layer of clear plastic over the paper, which creates an invisible barrier and protects it from moisture.
The lamination also increases the strength and durability of the sign, making it more resistant to wear and tear. It’s also cost-effective as the same sign can be used for several years without replacement.
