Is Cotton Canvas Fabric Waterproof? Make it Waterproof

Let’s talk about what to expect with cotton canvas and water in more detail in this article.

When you purchase cotton canvas workwear, you want it to protect you from the elements in addition to brush and debris. But is cotton canvas fabric waterproof?

You shouldn’t anticipate untreated cotton canvas workwear to be completely waterproof, even though cotton canvas will naturally repel water. The majority of cotton canvas workwear will receive an additional water-resistant finish treatment to make it even more water-resistant.

I’m going to demonstrate how to waterproof cotton canvas fabric at home for you today. It’s probably much simpler than you realize.

Is Cotton Canvas Fabric Waterproof?

Untreated cotton canvas workwear cannot be expected to be completely waterproof, despite the fact that cotton canvas will naturally repel water.

A very tight, robust weave is a canvas weave. This tight cotton weave expands and seals the weave when it becomes wet, helping to stop moisture from penetrating your skin.

The answer is that a canvas weave naturally keeps moisture from penetrating to your skin. The issue is that, despite keeping moisture out, no one wants to wear a sopping-wet work jacket.

Yes, the weave may help keep moisture from seeping through to your skin, but cotton will still absorb moisture, making the garment itself wet and heavy.

To help with this problem and prevent the canvas from absorbing water, there are two main solutions that are frequently used.

  1. A DWR or wax water-resistant finish is applied to the clothing.
  2. To help fend off moisture, a fabric blend is used.

How to Make Cotton Canvas Waterproof?

Before you start, I suggest reading through the following advice and recommendations.

  • Before you wax, make your project’s pieces.

I’ve discovered that doing this can help you save time and money. Wax the entire yard of canvas fabric if you think you’ll need it all at once. But it will save time to cut out the pieces you need first.

Even though this one may seem obvious, it deserves to be mentioned anyway. This will create such a mess that cleanup will be nearly impossible. So, after waxing all of my heavy-duty canvas fabrics, this is what I like to do.

  1. I let the towels I used cool and harden after I’ve finished waxing my canvas.
  2. I carefully fold them and store them in a garbage bag for the next time I need to wax some fabric after they have dried.

The extra wax in the towels can be absorbed into the next batch of fabric you are waxing, allowing you to use less wax overall.

  • When waterproofing any fabrics, be certain that the area is well-ventilated.

The smell of paraffin isn’t the best, and when you start ironing, the room will smell like burning wax. Smoke will also be produced. I prefer to wax my cotton canvas outside in a covered area if it’s warm enough outside, so make sure to plan ahead.

  • Remove the ceramic pot from the crockpot, add the wax, and microwave until almost melted to hasten the wax melting process.

When you take the pot out of the microwave, it’s going to be very hot, so be careful. Avoid allowing the wax to heat up to the point where it starts to pop and splatter all over your microwave. Use cling wrap to protect!

  • While waxing, fold the canvas by the full yard in half.

In order to flip the piece over, you will need less wax on the backside because any wax that has penetrated the top layer will soak through to the bottom layer. Smaller pieces can also be assembled using this step. merely generates less waste.

  • To keep your clothes safe, put on an apron.

Hang your pieces to dry over a shower rod to cure once you have finished waxing all of your fabric. Additionally, they can be folded and hung on a hanger.

Can Pure Cotton Resist Water?

The short response is no. Pure cotton products cannot resist water for two reasons, which are:

  • When pure cotton products are submerged, the cotton fibers absorb water, causing the product to quickly become wet and remain wet until all the water has evaporated from the fabric.
  • Since cotton fibers are also very flexible, it is extremely difficult for products made entirely of cotton to repel water. When wet, the fibers flex under the weight of the water rather than acting as a barrier against it.

There are numerous blends and products available to coat cotton because it cannot withstand moisture.

Conclusion: is Duck Canvas Fabric Waterproof?

Paraffin Wax is pressure-impregnated into duck canvas fabric to make it waterproof. This implies that the coating cannot be rubbed off.

A heavy-weight canvas fabric known as “duck canvas” is waxed canvas. A blend of different waxes is applied to it making it virtually a waterproof material. Backpacks, handbags, tents, and boat covers can all be made out of this material.


What Kind of Canvas is Waterproof?

Acrylic canvas, like cotton canvas, is a tight-weave fabric. It is waterproof but also breathable, more resistant to UV rays (exposure to the sun), snubs mildew, resists stains, is colorfast and available in every shade imaginable, and it looks fantastic.

Can Duck Canvas Be Used Outside?

Cotton or Duck canvas should not be left outside unless treated. They are susceptible to stains and do not resist mold or mildew. If not preserved, the colors will also fade. Compared to cotton canvas, duck cloth/canvas is more tightly woven, and oil cloth/canvas has been coated with linseed oil to make it water-repellent.

Can Canvas Get Wet from Rain?

Canvas is a durable material and is naturally slightly waterproof. Your canvas should only be slightly wet during a mist or light rain; otherwise, the water may not soak through at all.
