Structural & Cosmetic Repairs for Composites

Fiberglass Surface Repair

Fiberglass is the workhorse material for boat hulls, bathtubs, and shower units, offering a high strength-to-weight ratio. It consists of glass fibers embedded in a resin matrix, usually finished with a smooth gelcoat. Damage often appears as spider cracks, chips, or deep gouges that penetrate the gelcoat. If left untreated, water can seep into the laminate, potentially causing structural issues like osmosis or delamination, which are costly to fix.

Effective fiberglass repair restores both the protective outer layer and the structural integrity. Our repair solution bonds strongly to the fiberglass substrate, filling voids and sealing cracks against water intrusion. It can be sanded flush and polished to a high shine, seamlessly integrating with the original gelcoat for a professional-grade restoration that stands up to the marine or bathroom environment. It's a quick, durable fix for common composite issues.
