Epoxybond Pool Putty 2-Part Epoxy Putty — Underwater-Setting Repair for Pools & Spas, 1:1 Mix, Bonds Concrete/Fibreglass

Epoxybond Pool Putty is a two-part, hand-moldable epoxy putty that bonds and cures above or below water to stop leaks, fill cracks, and restore chips on concrete, fiberglass, tile and other pool surfaces.

If you're repairing a leak, chip, or crack in a swimming pool or spa and want a fast, durable fix without draining the water, this Atlas Minerals Epoxybond Pool Putty set is formulated to be mixed 1:1 by hand and applied directly where needed. It cures underwater, resists yellowing, sagging, and shrinking, and bonds to a wide range of materials so you can patch tile, concrete, and fiberglass with minimal tools or downtime.

How does Epoxybond Pool Putty work to stop leaks underwater?

The putty is a two-part epoxy system packaged for hand mixing that chemically reacts after kneading. Once blended and pressed into a crack or hole, it adheres to wet surfaces and sets while submerged, forming a hard, watertight bond.

• Mixes 1:1 by volume for straightforward activation.
• Cures in place underwater—no pool draining required.
• Hardens into a rigid patch that resists water pressure and wear.

Which surfaces can I repair with this putty?

Epoxybond is formulated to adhere to common pool and spa materials, making it versatile for many repair tasks. It works for both structural repairs and cosmetic fixes, though surface prep improves durability.

• Concrete and gunite—fill hairline to small structural cracks.
• Fiberglass—repair chips, gouges, and small delaminations.
• Ceramic and porcelain tile—restore broken or missing pieces and seal edges.
• Other substrates—bonds to metals and some plastics with proper cleaning.

How easy is it to apply for a DIY homeowner?

Application is intentionally simple: cut, knead, press, and smooth. No special tools, heat, or power equipment are required, and because it cures underwater you avoid the effort and cost of draining and refilling a pool.

• Hand-moldable—knead parts A and B together until uniform color.
• Apply directly to wet or dry areas; shape and tool with gloved fingers or a putty knife.
• Sets up without sagging or shrinking and resists yellowing over time.

What performance should I expect after it cures?

Once fully cured, the repaired area becomes a hard, permanent-feeling patch designed to maintain color and shape under typical pool conditions. It is intended for repair and sealing rather than structural load-bearing replacement.

• Maintains color—formulated to resist yellowing under sunlight and chemicals.
• Does not sag or shrink—holds its shape after curing for dependable seals.
• Long-lasting adhesion—creates a durable bond to treated surfaces when applied correctly.
