FAQ

Frequently Asked Questions

Yes, epoxy resin is ideal for wetting out fiberglass cloth and other reinforcements like carbon fiber and Kevlar. It saturates the fabric well and cures into a strong, durable laminate.

Yes. When used with the right resin, fiberglass cloth bonds well to wood, metal, foam, and other substrates.

The weight refers to ounces per square yard. Lighter cloth (e.g., 4oz) is more flexible and used for fine finishing; heavier cloth (e.g., 10oz) provides more strength and bulk.

Use sharp scissors or a utility knife. To reduce fraying, you can lightly mist the cloth with water or use tape to mark the cutting line.

Fiberglass cloth is used to reinforce composite materials in applications like boat building, surfboard repairs, auto bodywork, and structural laminates. It’s combined with resin to form a strong, lightweight composite.

Fiberglass cloth is woven for strength in specific directions, while chopped strand mat is made of randomly oriented fibers and is better for building bulk.
