Fiberglass Mat

The lightest weight .09 oz. fiberglass chop strand mat is sold by the yard (cut yardage is not returnable); the 3/4 oz. and 1.5 oz. fiberglass mat is sold in pre-cut lengths. Use different weights of fiberglass mat to achieve various results, as indicated below.

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.
