Nordstrand Fiberglass Mat 50in x 30ft Marine Grade Roll
This marine grade chopped strand fiberglass mat from Nordstrand provides 125 square feet of coverage at a width of 50 inches and length of 30 feet. The 1.5 ounce per square foot material ensures a balance between strength and flexibility. Designed specifically for boat, camper, and other watercraft repair, the mat is compatible with epoxy, vinyl ester, and polyester resins for versatile use.
The roll format allows convenient handling and easy cutting to your project needs, guaranteeing no weak spots or loose strands. This product is ideal for creating strong, durable repairs or reinforcements on hulls and decks, maintaining marine-grade quality to withstand water exposure and mechanical stresses.
SICCOMA Woven Fiberglass Cloth Tape 2in x 99ft Non-Adhesive Roll
The SICCOMA woven fiberglass cloth roll is a plain weave E-glass tape 2 inches wide and 99 feet long. Unlike chopped strand mats, this cloth is a continuous woven mesh, providing high tensile strength and dimensional stability. Its non-adhesive format allows for flexible use in applications such as pipe winding, seam reinforcement, and crack repair on boats and models.
At only 0.13 mm thickness, it’s a lightweight yet sturdy reinforcement layer compatible with many resins. The selvage edges minimize fraying for clean finishes on detailed marine repairs or molding projects. This tape is excellent for users seeking precision reinforcement or structural strengthening in narrow, curved, or confined boat areas.
Wesnoy 1708 Fiberglass Cloth Roll 6″ Wide by 360″ with Roller Tools
The Wesnoy fiberglass cloth roll measures 6 inches wide by 360 inches long, composed of robust 1708 fiberglass cloth noted for strength and flexibility. The product includes three fiberglass roller tools designed for varied application techniques, enabling smooth resin application and bubble elimination during the layup process.
This pack caters to both major area coverage and fine detail work. The cloth suits typical marine resins such as epoxy and polyester and excels in increasing structural integrity without excessive weight. Ideal for boat hull repairs, shower stalls, or tub reinforcements, the included rollers enhance ease of use and professional finish quality.
CRMCC Heavy-Duty Fiberglass Mat Roll 50″ x 360″ Chopped Strand Mat
Designed for demanding projects, the CRMCC 13 oz/yd² chopped strand mat roll measures an expansive 50 inches wide and 30 feet long. Its heavy-duty construction allows it to support large-scale marine repairs like boat hulls and decks, plus industrial applications like tank lining or automotive panel reinforcement.
The industrial-grade E-glass fibers are bound uniformly for fast resin saturation and maximum strength. Compatible with polyester, vinyl ester, and epoxy resins, this mat reduces seams and speeds application thanks to its wide format. It offers exceptional rigidity, durability, and resin holding capacity for prolonged performance in harsh marine environments.
SIMPLYHARDWARE 1708 Fiberglass Cloth Roll 8″ Wide x 360″
The SIMPLYHARDWARE 1708 fiberglass roll features an 8-inch width by 360-inch length, made from marine-grade biaxial fiberglass. This versatile mat is commonly used for boat molding, roofing, and repair tasks that require balanced strength in multiple directions.
Its compatibility with epoxy, polyester, and vinyl ester resin systems allows for wide application in watercraft repair. The biaxial weave provides uniform strength and structural reinforcement with easy handling. This roll is a good solution for improving boat hull integrity or creating durable composite layers effectively.
Buying Guide for Fiberglass Rolls for Boats
1. Type of Fiberglass Material
Choose between chopped strand mats, woven cloth, biaxial mats, or mesh tapes depending on the repair area and required strength. Chopped strand mats excel in rapid resin saturation and structural reinforcement, while woven cloths and biaxial mats provide directional strength and flexibility, ideal for layered laminates.
2. Roll Size and Coverage
The roll width and length should match your project scope. Wide rolls (50 inches or more) minimize seams on large hull surfaces, enabling quicker application and a stronger finish. Narrower rolls or tapes are better suited for seam reinforcement, patches, or curved surfaces.
3. Weight and Thickness
Heavier mats (over 10 oz/yd²) provide higher rigidity and durability, essential for structural components. Lightweight mats (around 1.5 oz) offer flexibility and are great for cosmetic repairs or layering. Consider the balance between weight and application ease when selecting your material.
4. Resin Compatibility
Ensure the fiberglass is compatible with your chosen resin system: epoxy, polyester, or vinyl ester. Most marine-grade fiberglass rolls accommodate all three, but checking compatibility maximizes adhesion, curing quality, and longevity in marine environments.
5. Additional Tools and Accessories
Some bundles include roller tools or fillers to aid resin application and air bubble removal, improving your finish quality. Consider kits or combos if you need comprehensive repair solutions beyond just the fiberglass material.
6. Durability and Marine-Grade Standards
Marine-grade fiberglass is designed to resist water, UV damage, and salt corrosion. Look for products specifically marketed for marine use to ensure longer-lasting repairs and optimal performance in wet, harsh conditions.
