Waterproof Canvas

Canvas is a popular material due to its durability and versatility. But when it comes to water exposure, not all canvas is created equal.

Understanding the difference between water-resistant and waterproof canvas can help you choose the right fabric for your needs. In this article, we’ll explore the properties and limitations of water-resistant canvas and the methods used to make canvas waterproof.

We’ll also look at natural solutions for waterproofing canvas, such as wax and linseed oil coatings.

Water-Resistant Properties

Water-resistant canvas is designed to repel water to some degree, making it suitable for light rain and moisture. It is made by weaving cotton or linen fibers tightly together, creating a material that is less permeable than standard fabric.

This tight weave prevents water from seeping through the fabric easily. However, water-resistant canvas does not provide complete protection from water, and it can only resist water up to a certain point.

With prolonged exposure to water, eventually, water-resistant canvas will become saturated, leading to sogginess, and seepage of water.


Water-resistant canvas has limitations when it comes to water exposure. If it is exposed to water for an extended period, such as in heavy rain or a wet environment, it will eventually become saturated.

The waterproofing quality of cotton and linen fibers can be diminished over time due to natural wear and tear or exposure to the elements. When this happens, the fabric will become soggy and uncomfortable, which can lead to damage or mold growth.

Methods to Make Canvas Waterproof

To make canvas waterproof, manufacturers use various techniques to improve the fabric’s water resistance. One way is to blend cotton or linen fibers with synthetic materials like aramid fibers.

This blend results in a material that is waterproof, heat-resistant, and abrasion-resistant. Some manufacturers may also use gel coatings, petroleum-based sealants, or sprays to make canvas waterproof.

Another method is adding chemicals such as Durable Water Repellent (DWR) coatings, Fluorocarbon sprays, and fluoropolymers, which are used to create a barrier that repels water without being absorbed by the fabric. Wax or silicone coatings can also be applied to canvas as waterproofing agents.

The wax coating can be made up of beeswax or paraffin wax and provides a significant coating that repels water. The silicone coating can be applied via sprays and covers the canvas fibers, preventing water from penetrating the material.

Natural Canvas Waterproofing Solutions

If you prefer natural solutions for waterproofing canvas, there are several methods you can use to create your own water-resistant canvas. Beeswax and paraffin wax are two readily available natural waterproofers that can be applied to canvas at home.

To make a wax coating, rub a bar of beeswax or paraffin wax onto the material and use a hairdryer or heat gun to melt the wax and create an even coating. The wax will create a barrier that repels water and provides a natural waterproofing solution.

However, it is important to note that wax coatings can change the color and texture of the canvas material. Another natural solution for waterproofing canvas is a linseed oil coating.

Linseed oil is an oil extracted from flax seeds and can be used to protect canvas from water damage. To make a linseed oil coating, mix two parts boiled linseed oil with one part turpentine and one part white spirit.

Apply the mixture to the canvas with a paintbrush and allow it to dry for several hours. After that, your canvas should be more water-resistant.

Be warned that linseed oil is known to yellow and darken over time, making it a less aesthetically satisfying choice.


In conclusion, choosing the right canvas depends on the application you need it for. For light rain and moisture, water-resistant canvas will work fine.

However, a heavier duty application at risk of extensive water exposure may require waterproof canvas. The methods used to make canvas waterproof work relatively well, but natural waterproofing solutions offer not only benefits to the environment but also aesthetic satisfaction.

Waxed and oil coated canvas maintain their natural texture, making them less noticeable in outdoor settings.

Synthetic Canvas Waterproofing Solutions

Canvas is a popular fabric used in outdoor gear and marine equipment due to its durability and strength. However, it is not naturally waterproof, making it prone to water damage.

Synthetic canvas waterproofing solutions have become increasingly popular with the development of modern fabric technology. These solutions offer a variety of benefits, including increased water resistance, durability, and longevity.

In this article, well explore three synthetic canvas waterproofing methods: petroleum-based polymer sealants, DWR coatings, and fluoropolymer sprays.

Petroleum-Based Polymer Sealant

One of the most popular synthetic waterproofing methods for canvas is the use of petroleum-based polymer sealants. These sealants are formulated to penetrate the fibers of canvas, creating a water-resistant barrier.

This solution is commonly used for outdoor gear and marine equipment, such as boat covers or outdoor tents. The sealant works by filling in the gaps and pores in the canvas, blocking water from penetrating the fabric.

Using a petroleum-based polymer sealant for canvas is a simple process. First, clean and dry the canvas thoroughly.

Then, apply the sealant evenly, making sure to cover the entire surface. Allow the sealant to dry as per the manufacturer’s instructions.

Once dry, the canvas will be more water-resistant, durable and more resistant to the elements.

DWR Coating

Durable Water Repellent (DWR) coatings are synthetic materials that are applied to the surface of canvas to create water-repellent properties. When applied to canvas, the coating essentially coats the fabric’s fibers with hydrophobic features, causing water to bead up and run off the canvas surface.

DWR coatings are commonly used for outdoor clothing and equipment, such as tents, backpacks, and rain jackets. There are two main types of DWR coatings: silicone-based coatings and fluoropolymer coatings.

Silicone-based coatings are known for their durability and resistance to abrasion. They tend to have a shorter lifespan in areas of high friction such as zippers and backpack straps.

Fluoropolymer coatings are usually seen as a low-cost alternative to silicone and are known for being easy to apply. Both types of DWR coatings are effective in making canvas water-resistant.

Fluoropolymer Spray

Fluoropolymer sprays are cheap, easy to use, and can add a substantial amount of water-repellent coverage to canvas. These sprays contain fluorochemicals, which create a barrier on the surface of the canvas that repels water.

Fluoropolymer sprays are commonly used for outdoor gear, including tents, tarps, and awnings. These sprays can be an effective solution for waterproofing canvas with a low cost.

To apply a fluoropolymer spray, first, clean and dry the canvas thoroughly. Then, evenly spray the surface of the canvas with the spray, making sure to cover the entire surface evenly.

Allow the spray to dry completely as directed by the manufacturer. Once the spray is dry, the canvas will be more water-repellant.


Synthetic waterproofing methods for canvas are effective solutions for making canvas water-resistant. Petroleum-based polymer sealants, DWR coatings, and fluoropolymer sprays are all options available to increase canvas water resistance.

When looking to choose the suitable waterproofing method, it is important to consider the application, durability, and cost-effectiveness.
