Use sharp heavy-duty scissors or shears. Because of its thickness, it may be harder to trim cleanly than lighter fiberglass cloth.

It’s relatively stiff compared to other fiberglass fabrics, but it can still conform to gradual curves with proper wet-out and pressure.

Yes, and you usually should. Woven roving builds thickness fast but has a coarse weave, so it is almost always alternated with chopped strand mat: the mat fills the weave and ties the layers together for a stronger, void-free laminate. A common schedule is mat, roving, mat. Finish with cloth or mat for a smoother surface.

Woven roving works well with polyester, vinyl ester, and epoxy resins. Polyester is common in boatbuilding, while epoxy is preferred for repairs and higher strength applications.

Woven roving is much thicker and heavier than standard fiberglass cloth. It’s used for strength and bulk, while cloth is typically used for finishing or lightweight laminates.

Woven roving is a heavy-duty fiberglass fabric made from continuous strands woven into a coarse, crisscross pattern. It provides high tensile strength and is ideal for structural laminates in marine and industrial applications.
