Fiberglass Mat 1.5 Oz 10"

The most economical of reinforcing fabrics, mat is random lengths of glass fibers laid down in a random pattern and held together with a resin-soluble binder. This construction provides equal strength in all directions, wets out easily, and quickly builds thick, rigid laminates. Used to finish laminates with a smooth, resin rich layer and to reinforce gelcoat repairs where stress cracks are involved. Great for model building. Compared to woven cloth, laminations made of mat use more resin, making them more rigid, more waterproof, but overall lower in strength. Because of the binders used to hold mat together, it is not a recommended fabric to use with epoxy.
