Why KA 46 Waterproof Canvas Is Better Than Standard Canvas

Many traditional canvas fabrics are made from 100 percent cotton and may not include protective coatings. While they can be durable, they often require additional treatment for outdoor use.

KA 46 coated canvas improves on standard canvas in several ways.

Stronger and More Durable

The polycotton blend increases tensile strength, making the fabric less likely to tear or stretch compared to standard cotton canvas.

This makes it suitable for projects that require long-term durability.

Better Weather Protection

Standard canvas may absorb water unless treated. KA 46 fabric includes a water-repellent coating that helps protect against rain and outdoor conditions.

This makes it more reliable for outdoor shelters and protective covers.

---

Resistant to Dirt and Mildew

The coated finish also helps prevent dirt buildup and mildew formation, which are common issues with untreated canvas fabrics.

---

Breathable Compared to Synthetic Fabrics

Unlike some fully synthetic waterproof materials, KA 46 polycotton canvas remains more breathable, helping reduce condensation in enclosed spaces like tents.
