How To Waterproof A Canvas

There are times when we can never contain the forces of nature. This only proves that nature is truly powerful and can destroy anything. So the only way we can do it is by protecting ourselves from the raging effects of nature.

One way to do this is by waterproofing. Waterproofing was an excellent technique to prevent water penetration into any material.

Whenever a material is waterproofed, a specific waterproof material designed to provide maximum protection against the imminent effect of water is applied. This, in turn, acts as a wall between the material and the water.

There are many types of waterproofing. One of them is the waterproofing of the canvas. This method is used in particular on canvas materials.

In most cases, the typical type of cotton canvas is already a waterproof material. Therefore, it does not require waterproofing. Its fibers swell every time they are exposed to water, thus closing the mesh of the canvas.

However, due to the tarp’s vulnerability to mold and “bird droppings”, it is still subject to tarp waterproofing. This is because the waterproofing of the canvas not only protects the canvas from water but also from other substances that can damage the object.

So for those who want to know about tarp waterproofing, here are some tips you should know:

1. Do not use silicone-based waterproofing cloths.

Never attempt to use silicone-based canvas waterproofers on acrylic canvas. The silicone collides with the original application.

Normally, acrylic tarp contains primarily a waterproofing chemical known as fluorocarbon, which in turn repels the silicone material when applied. If this happens, it will result in irregular treatment. Silicone can also remove the “stain” substance from acrylic canvas.

2. Use a fluoropolymer product.

When waterproofing the canvas, it is better to use a fluoropolymer-based substance. This type of tarpaulin waterproofing is compatible with acrylic tarps. Therefore, it will result in a more durable and strong acrylic canvas.

3. Use a waterproof material that contains petroleum.

Petroleum based materials have long been proven effective for waterproofing tarpaulins. They are very compatible with acrylic canvases. Petroleum-based substances work better for waterproofing tarps than water-based ones.

The best way to identify a petroleum-based substance for use in tarpaulins is by its pungent odor.

4. When waterproofing the tarp, do so outdoors.

It is better to waterproof the tarp outside the house due to the strong smell of the substance. You may suffocate once you do this indoors. Therefore, it is best to waterproof the tarp where there is adequate ventilation.

In addition, these strong substances that are used to waterproof tarps can also damage your plastic furniture. Therefore, you must take special care when waterproofing the canvas.

5. Use protective covers for sensitive furniture.

If you are going to do a canvas waterproofing over a canvas cover, it is best to protect your plastic furniture before beginning the process. You can do this by placing a sheet on the plastic materials.

6. Do a site test first.

It is better that before starting the process, first do a sample test. This is to see if the substance used to waterproof the canvas will not discolor the canvas or cause further damage.

7. Remove the tarp from the boat.

It is better that before you start waterproofing, first remove the tarp from the boat. This is to ensure that hard surfaces do not slip. In addition, there are waterproofing substances that can cause a harmful reaction against gelcoat.

However, if you find it boring and impractical, try to protect all areas vulnerable to “overspray”.

8. First let it dry.

After waterproofing, allow the canvas to dry before reinstalling. This will quickly remove the pungent odor.

However, experts strongly suggest that after the canvas has dried, it would be best to apply a second dose of waterproofer. This is to ensure the durability of the material. It is still safe to do this and will not affect the overall condition of the fabric.
