More about this item

WEST SYSTEM 740-20 Fiberglass & Repair

This lightweight 4 oz woven fiberglass fabric is ideal for applications requiring excellent conformability, smooth finish, and moderate reinforcement without adding significant weight or stiffness. The 50-inch width provides generous coverage for a wide range of projects, while the 20-yard length offers substantial material for large-scale marine construction and repair work.

Lightweight, Flexible Reinforcement:

At 4 oz per square yard, this is one of the lightest woven fiberglass fabrics available, making it perfect for applications where you need reinforcement and moisture protection without adding bulk or rigidity. The lightweight construction drapes beautifully over complex curves and contours, conforming smoothly to virtually any surface shape.

Superior Finish Quality:

The fine weave pattern and light weight of this fabric create exceptionally smooth laminates with minimal surface texture. This reduces the amount of fairing and finishing work required, making it ideal for bright-finished wood applications, clear-coated surfaces, or anywhere a smooth, professional appearance is important.

Extended Length for Large Projects:

The 20-yard length provides substantial material for professional boatyards, contractors, and large-scale projects. This extended roll reduces the frequency of reordering and ensures you have ample fabric on hand for major construction or repair operations.

Key Benefits:

  • Lightweight: 4 oz weight minimizes added bulk and stiffness
  • Excellent Drape: Conforms smoothly to complex curves and contours
  • Smooth Finish: Fine weave creates minimal surface texture
  • Quick Wet-Out: Lightweight fabric saturates easily with epoxy
  • Wide Coverage: 50-inch width reduces seams on large surfaces
  • Extended Length: 20-yard roll for large-scale projects
  • Versatile Applications: Ideal for sheathing, repairs, and light reinforcement

Common Applications:

  • Sheathing wood surfaces for moisture and abrasion protection
  • Bright-finished wood applications requiring smooth surface
  • Lightweight hull and deck repairs
  • Covering foam or balsa core materials
  • Creating smooth, clear-coated composite surfaces
  • Light reinforcement where flexibility is important
  • Cosmetic overlays and finish layers

This 20-yard roll provides exceptional value for professional operations and large-scale projects. Whether you're sheathing wooden hulls, creating smooth finish layers, or performing lightweight repairs, this 4 oz fiberglass fabric delivers exceptional conformability and finish quality for professional results in demanding marine environments.
