Our recommended epoxy for fiberglass tubs is the Loctite Epoxy Weld, which provides a strong and durable bond for repairing cracks or leaks on fiberglass surfaces. It is waterproof and can also be used to fill in gaps or holes. Its two-part formula allows for easy mixing and application, and it sets in just 5 minutes. Once fully cured, the epoxy can be sanded, painted, or even drilled into. The Loctite Epoxy Weld is a reliable and versatile solution for anyone looking to repair their fiberglass tub.
