How to Repair a Crack in Fiberglass

2017-09-19

Glass reinforced plastic (GRP), known as fiberglass or glass wool, is thin fibers of polymer (plastic) woven together with strands of glass. Fiberglass is used in innumerable consumer and industrial products from airplanes and automobiles to showers and insulation. When used in a finished product, fiberglass is mixed with a bonding material such as epoxy or thermoplastic, in order to shape it and strengthen it. There are some health hazards associated with handling GRP, especially when it's sold as glass wool.

Always wear a face mask when working with GRP so as not to breathe in any glass particles. It's also advisable to wear gloves, so the glass strands don't cut your fingers [source: New York City].
