Intro
Waterproof canvas is a rugged, versatile fabric used for tents, awnings, tarpaulins, truck covers, and outdoor gear. By applying specialized coatings and finishes, ordinary canvas is transformed into a water-resistant or fully waterproof material. Pakistan Fibres supplies bulk waterproof canvas tailored to industrial, outdoor, and commercial applications, meeting both performance and compliance requirements.
Water-Resistant vs Waterproof
It is important to distinguish between water-resistant and waterproof canvas:
- Water-Resistant: Canvas treated with light coatings that repel moisture and withstand light rain or splashes, but may allow water through during prolonged exposure.
- Waterproof: Canvas treated or laminated with heavy-duty coatings that create a complete barrier to water, suitable for tents, tarpaulins, and covers exposed to heavy rain.
| Treatment Type | Description | Common Chemicals / Processes | Applications |
|---|---|---|---|
| Waxed Canvas | Traditional method where natural wax is applied to cotton canvas. Provides water resistance with a vintage look. | Beeswax, paraffin wax, linseed-based compounds | Bags, jackets, tents, covers for outdoor furniture |
| PU-Coated Canvas | Polyurethane applied as a coating to create a flexible water barrier while retaining fabric breathability. | Polyurethane dispersions (Germany, Japan, USA) | Tents, awnings, industrial tarps, backpacks |
| PVC-Laminated Canvas | Polyvinyl chloride layer laminated onto fabric for 100% waterproof performance; heavier but very durable. | PVC plastisols, phthalate-free PVC (EU compliant) | Truck covers, industrial curtains, outdoor flooring |
| Acrylic-Coated Canvas | Acrylic polymers applied for water repellency with UV resistance; popular in marine and outdoor textiles. | Acrylic emulsions with fluorocarbon or silicone additives | Boat covers, awnings, garden umbrellas |
| Fluorocarbon / Silicone Repellents | Modern repellents that cause water to bead and roll off; highly durable but more expensive. | Fluorocarbon C6 (eco-friendly), silicone-based coatings | High-performance outdoor gear, premium tents, apparel |
How Waterproofing Works
Waterproof coatings create either a physical barrier or a chemical surface modification that prevents water molecules from penetrating the fabric weave:
- Wax & Oils: Fill fabric pores, causing water to bead up.
- Polyurethane & Acrylic Coatings: Form a thin polymer layer that blocks water but may allow some breathability.
- PVC Lamination: Creates a non-porous film, making fabric fully waterproof but less breathable.
- Fluorocarbon & Silicone: Alter fabric surface energy, forcing water to roll off without absorption.

Industry Applications
Outdoor industries use waterproof canvas for tents, awnings, and tarpaulins. Transport companies rely on it for truck covers and cargo protection. Marine and leisure sectors use it for boat covers and umbrellas. Fashion and bag industries use waxed and PU-coated canvas for weatherproof designs. Industrial users employ PVC-laminated canvas for heavy-duty applications.
Export Packaging & Shipping
Waterproof canvas is supplied in rolls wrapped with moisture-proof poly. Heavy grades can be bale-packed. Each roll labeled with size, GSM, and waterproof treatment type. Palletization supported for container loading. Both FCL and LCL shipments available, with reinforced cartons for LCL cargo to prevent compression. We follow buyer manuals for retailer-specific packaging when required.
