Commonly used as a finish layer. 3/4 oz. Builds thickness. 1.5 oz. Adds bulk quickly. Also great as an initial layer when bonding repair work. Note: Chop strand fiberglass mat is not compatible with epoxy resin systems. Instead, use polyester resin systems to wet out this type of material. This is because polyester resins break down the styrene binder, allowing fibers to become completely saturated. Need polyester resin, spreaders, thickeners, or other supplies for your project?
