Make fast, permanent repairs—even underwater—with this hand-kneadable epoxy repair putty. Designed for pools, spas, and plumbing, this specialty epoxy mixes in about one minute and bonds strongly to fiberglass, PVC, metal, concrete, wood, ceramic, glass, and most plastics.

Ideal for sealing cracks, holes, and leaks, this epoxy sets in 20–30 minutes and cures to a durable, machinable finish that can be drilled, sanded, tapped, or painted. A fade-resistant dye turns the putty fiberglass white after mixing and stays bright even with UV exposure.

Perfect for repairing pool shells, PVC fittings, returns, skimmers, steps, and light niches, this epoxy forms a watertight seal and works above or below the waterline. Trusted for strong adhesion, long-lasting durability, and quick results when downtime isn’t an option.
