FAQ

Frequently Asked Questions

4oz Fiberglass Woven Roving

Can epoxy resin be used with fiberglass cloth?

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.

Can fiberglass cloth be used on wood or metal?

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

What does the weight (oz) of fiberglass cloth mean?

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.

How do I cut fiberglass cloth?

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.

What is fiberglass cloth used for?

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.

What’s the difference between fiberglass cloth and chopped mat?

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.
