Emerkit 2-Pack Epoxy Putty is a high-strength, moldable, two-part repair compound famous for its ability to set underwater. It consists of two separate components—a resin stick and a hardener stick—that are blended together by hand in an equal 1:1 mix ratio. Once combined, it functions like clay, allowing you to mold it into shape before it cures rock-hard like concrete.

Key Capabilities & Specifications

• Underwater Setting: It cures seamlessly under fresh or salt water, meaning you can plug leaks or fix loose tiles in swimming pools, spas, and water tanks without draining them first.
• High Structural Strength: Once fully cured, it features a massive compressive strength of 82 MPa and a tensile strength of 10.5 MPa.
• Post-Cure Workability: After hardening, it behaves like solid stone or metal. It can be drilled, tapped, machined, sawed, filed, and painted.
• Material Versatility: It forms a permanent bond to practically any rigid surface including concrete, fiberglass, ceramics, timber, glass, metal, and aluminum.
• Zero Shrinkage: The material does not run, drip, shrink, or pull away from surfaces while setting.
• High Resistance: It is non-conductive (great for insulating electrical wires), oil-resistant, and can withstand temperatures up to 150°C.

Common Uses

• Pool & Spa Maintenance: Sealing cracks in plaster, regrouting tiles, and repairing skimmers or pool lights.
• Plumbing & Tanks: Patching leaking pipes, water troughs, roofs, radiators, and fuel or oil sumps.
• Electrical Insulating: Repairing electric fence components, plugs, solar power connectors, and exposed wiring.
• Marine & Hobbies: Repairing boat hulls, rebuilding broken tooling handles, anchoring coral frags for propagation, and sculpting.

Basic Instructions for Use

1. Prepare the Surface: Clean, degrease, and roughen the rigid surface with sandpaper to ensure a strong grip.
2. Mix Equally: Cut off equal portions (1:1 ratio) of the resin and hardener.
3. Knead with Wet Hands: Thoroughly mix the two parts together using wet hands until they reach a completely uniform color with no marbling. Using wet fingers stops it from sticking to your skin and helps you smooth the finish later.
4. Apply and Shape: Work the putty firmly into the crack or joint. It hardens in roughly 2.5 hours at 18°C, reaching its full cure strength in 24 hours. Unused, unmixed putty can be stored airtight to keep it soft for future use.
