Canvas waterproofer is a product designed to make canvas materials resistant to water. Canvas is a popular fabric for tents, boat sails, tarps, shoes, and other outdoor gear due to its strength and durability, but it can absorb water if not treated. Waterproofing enhances the canvas’s ability to repel water and protects it from the detrimental effects of prolonged moisture exposure.
Here’s how canvas waterproofer works and how to use it:
How It Works:
- Barrier Creation: Waterproofers typically create a barrier on the canvas surface, which prevents water molecules from passing through. This barrier can be due to a physical film or a chemical treatment that repels water.
- Filling Pores: Canvas, being a woven fabric, has small pores. The waterproofer works to fill these pores to prevent water from seeping through.
- Repellency: Some waterproofing products contain hydrophobic (water-repelling) substances that cause water to bead up and roll off the canvas surface instead of soaking in.
Types of Canvas Waterproofers:
- Wax-based: Historically, paraffin wax and beeswax were used to waterproof canvas. These waxes are still popular today, especially for a more traditional and rugged aesthetic.
- Silicone-based: These sprays or liquids create a protective barrier that repels water effectively.
- Polyurethane-based: These create a more plastic-like film on the canvas, providing a solid barrier against water.
- Teflon-based: These utilize the hydrophobic properties of Teflon to repel water.
- Water-based: Non-Toxic, Won’t darken canvas, Breathable. This is a great all round option and it’s what we sell here on this website. Dynaproof water-based re-waterproofer product.
When choosing a canvas waterproofer, consider the specific needs of your canvas item, the environmental conditions it will face, and any aesthetic preferences you might have. Remember that while waterproofing can significantly improve the water resistance of canvas, no treatment will make it completely and permanently waterproof under all conditions.
