3M Scotchgard™ Heavy Duty Water Shield — 10 oz., Case of 6
Scotchgard Heavy Duty Water Shield is a professional-strength fabric protector that repels water and resists staining across a wide range of materials — from boat covers and canvas tarps to outerwear, gear, and upholstery. A single application delivers durable, breathable protection that holds up through use and storage.
Key Features
- Broad material compatibility — safe for polyester, nylon, polypropylene, cotton, leather, suede, and more
- Heavy-duty water repellency — beads and sheds water on contact; effective during active use and in storage
- Maintains fabric breathability — does not seal or stiffen treated materials
- Dries odorless — no lingering chemical smell after application
- High coverage rate — one 10 oz. can covers up to 60 sq. ft. on light nylon or 20 sq. ft. on heavier fabrics
- One-application protection — durable results without repeated treatments
Recommended Applications
- Boat covers, bimini tops, and canvas enclosures
- Outdoor gear: backpacks, luggage, tents, and tarps
- Rain gear, outerwear, and work jackets
- Patio furniture cushions and umbrellas
- Leather and suede upholstery
Parts Desk Insights
The case-of-6 format is the right buy for marine dealers, outfitters, and anyone maintaining a fleet of boats or a large inventory of canvas and fabric gear. At 10 oz. per can, each unit is sized for a focused application — a full boat cover, a set of cushions, or a bimini top — making it easy to hand off individual cans to customers or use across multiple jobs without waste. Scotchgard Heavy Duty Water Shield is the go-to recommendation for customers asking how to extend the life of a boat cover or re-treat canvas that has lost its water repellency after washing. For best results, advise customers to apply to clean, dry fabric and allow full drying time before exposure to water.
