How Do You Make Canvas Waterproof

Canvas, renowned for its strength and durability, has been a popular choice for a variety of purposes ranging from painting to camping. Despite its many benefits, canvas is not inherently waterproof. But fear not! There is a simple solution to make it resistant to water, allowing you to use it outdoors worry-free. In this blog post, we will guide you through the necessary steps to waterproof your canvas.

What You’ll Need:

  • Canvas fabric
  • Waterproofing spray or wax
  • A brush or sponge
  • Clean cloth
  • Water for testing

Step-by-Step Guide to Waterproofing Canvas:

Step 1: Clean the Canvas

Before we start with the waterproofing process, it’s important to ensure that the canvas is clean. Dust and dirt can hinder the waterproofing process, so make sure you clean it thoroughly. Use a clean, dry cloth to wipe off any visible dirt and dust from the canvas.

Step 2: Apply the Waterproofing Solution

The next step involves applying the waterproofing solution. There are two main types of waterproofing solutions that you can use – spray or wax.

If you’re using a spray, hold the can about 6 inches away from the canvas and spray evenly. Make sure all areas of the canvas are covered.

For those who opt for the wax option, you’ll need a brush or sponge to apply the wax evenly over the canvas. Start from one end and work your way to the other, ensuring every part of the canvas is covered.

It’s worth noting that the waterproofing solution should be applied when the canvas is dry. If it’s wet, the solution might not adhere properly, compromising its waterproofing ability.

Step 3: Let it Dry

Once you’ve applied the waterproofing solution, give it time to dry. The drying period varies based on the type of waterproofing solution used and the prevailing weather conditions. Typically, it takes between 24 to 48 hours.

Step 4: Test its Waterproofness

After the canvas has dried, it’s time to test if it’s indeed waterproof. Pour a bit of water on the canvas. If the water beads up and rolls off, then congratulations, your canvas is waterproof! If the water gets absorbed, you might need to apply another coat of waterproofing solution.


Waterproofing a canvas is a relatively simple and straightforward process. With just a few items, you can make your canvas resistant to water and extend its durability. So, go ahead, give it a try, and unlock the full potential of your canvas!


When using a waterproofing solution, make sure to do it in a well-ventilated area. Always follow safety instructions provided by the manufacturer.
