GCSR Labs

GCSR Labs is a Gold Coast, Queensland-based supplier of a fibre-fill epoxy resin developed specifically for surfboard ding repair. According to the company's website, the resin cures within minutes when exposed to sunlight, requires no mixing and no application of fibreglass cloth, and is formulated to cure in any temperature condition. It is designed to work on both EPS (epoxy) and polyurethane surfboards, leaving a tack-free finish that can be sanded shortly after curing. The company states the product is made in Gold Coast, Australia, and positions it as a way for surfers to complete their own repairs and get back in the water quickly, while also noting a focus on minimising environmental impact. GCSR Labs operates primarily as an online retailer of this specialised repair resin rather than as a general surf-gear or apparel store.
