- Choose a waterproofing spray or seam sealer designed for canvas.
- Hang the bag in an open area.
- Lightly mist the entire surface with the product.
- Continue spraying until no more liquid is absorbed by the fabric.
- Let it dry outside for at least 24 hours before using.
2. Alum Powder and Detergent
You’ll need alum powder, washing detergent, a bucket or bowl, and of course the backpack you want to waterproof.
- Prepare a detergent mix. Fill a bucket or bowl with warm water and dissolve two tablespoons of washing detergent.
- Soak the backpack in the detergent mix until saturated
- Dry the backpack.
- Prepare an alum solution by dissolving one tablespoon of alum powder per gallon of warm water

a. Materials You’ll Need
To get the job done, you’ll need:
- Wax
- Cotton balls
- Alum powder
- Detergent
- Clean cloth
b. Prepare The Mix
Mixing the wax, cotton balls, alum powder, and detergent is an essential step in protecting your bag.
To make your canvas tote bag waterproof, begin by melting the wax in a double boiler.
| Chemical | Way to Waterproof a Canvas |
|---|---|
| Wax | Melt |
| Cotton Balls | Mix |
| Alum Powder | Add |
| Detergent | Soak |
Once mixed together, you are ready to soak your bag in the detergent mixture and continue on with the waterproofing process.
c. Soak In Detergent Mixture
Soak your bag in a mixture of wax, cotton balls, alum powder, and detergent to give it a protective layer.
For best results when waterproofing a cotton canvas tote bag, make sure to cover it completely with the mixture.
d. Prepare The Alum Mixture
Use 2 tablespoons of alum for every cup of water and mix until completely dissolved. This will create a mixture that you can soak your leather bag or canvas item into.
Make sure that the wax has been removed from the acrylic canvas fabric. After this, dip it in the alum mixture and leave it for 15 minutes before rinsing off with cold water.
e. Soak In Alum Mixture
Dip your canvas bag into the alum mixture and leave it for 15 minutes.
Follow these steps to waterproof your canvas bag:
- Inspect the bag and brush off any dirt or debris
- Gently pour the alum mixture over the canvas bag
- Leave it submerged in the mixture for 15 minutes
- Rinse thoroughly with clean water
- Hang dry and inspect for any signs of wear
3. Using Wax
To waterproof your canvas backpack with wax, you’ll need a block of beeswax, an old towel or rag, and a heat source.
Before applying the wax to your backpack, it’s best to test it out on a scrap piece of cloth; this will help ensure that the wax won’t discolor or damage your bag.
Start by melting the beeswax in a double boiler over low heat, then use the rag or towel to rub it onto the outside surface of the bag.
Once you’ve applied all of the wax thoroughly to both sides of your pack, turn it inside out and apply another layer of melted wax for extra protection.
Finally, let the wax dry until it is completely hardened, and voila. Your canvas backpack is now waterproofed.
a. Materials You’ll Need
You’ll need:
- Beeswax or waterproofing spray
- Clean cloth
- Sponge
- Double boiler
- Rag or towel
- Special canvas cleaner or Soft brush
The type of canvas you have will determine how much wax to use: if it’s untreated, you may want to double the amount of wax used.
b. Preparation of the Wax
Apply a thin layer of wax to your bag with a cloth, making sure to cover the entire surface evenly.
To make sure you waterproof your canvas tote properly, here are 3 easy steps:
- Clean the surface of the bag thoroughly
- Test a small area of the bag first with wax and then submerge it into the water
- Apply additional layers of wax as needed
Pay attention when applying wax on the surface and don’t forget to check if any areas lack coverage.
c. Applying the Wax
There are several ways to make sure your canvas backpack is waterproofed, and this method involves applying wax onto the canvas.
Here are some methods to make it easier:
| Method | Tools | Time Required |
|---|---|---|
| Ironing | Cloth or brush, iron, heatproof mat & wax | 30 minutes |
| Boiling | Pot/pan, Water, Wax & Cloth | 15 minutes |
| Freezing | Plastic bag/container, ice cubes & wax | 10 minutes |
Alternative Methods for Waterproof Your Canvas Backpack
There are several alternative methods you can use to make it water-resistant.
Using wax, silicone, or polyurethane-based sprays is the most common way to keep moisture out.
You can also utilize a fabric sealant that is specifically designed for canvas products.
Additionally, you can purchase a pre-made water-resistant bag cover that slips over your existing bag and provides an extra layer of protection from rain and other liquids.
| Method | Pros | Cons |
|---|---|---|
| Wax | Easy to apply; good for light showers | Not suitable in heavy rains; requires frequent re-application |
| Silicone Spray | Long-lasting protection; prevents staining by water/dirt | Can cause discoloration of material; may require special cleaners when removing residue |
