Fiberglass Cloth | 4oz x 42" E-Glass

4oz Fiberglass Cloth – 42” Wide (Sold by the Yard)

This 4oz E-glass fiberglass cloth is the industry standard for surfboard and paddle board construction. At 42 inches wide, it’s perfectly sized to span the full width of most paddle boards including lapping under the rails, minimizing waste and saving time in your lamination process.

Featuring a plain weave with a balanced 50/50 yarn construction—equal strands running nose-to-tail and rail-to-rail—this cloth lays down smooth and wets out easily with either epoxy or polyester resin systems. It’s lightweight yet strong, offering excellent clarity and a clean finish that’s ideal for top coats or waterproof sealing over wood and foam cores.

Whether you’re building a new board or doing repairs, this cloth delivers professional-grade performance trusted by some of the top names in the surf industry.
