Make fast, permanent fixes—even underwater. This hand-kneadable specialty epoxy mixes in about a minute and bonds tenaciously to fiberglass, metal, wood, concrete, ceramic, glass, and most plastics (including PVC). It sets in 20–30 minutes, then can be drilled, tapped, sanded, or painted. A fade-resistant dye turns the putty fiberglass white after mixing and stays bright white even with UV exposure.

Great for

• Cracks, holes, and leaks in pools and spas

• PVC fittings and returns (forms a cuff around pipes)

• Chips in fiberglass steps, skimmers, and light niches

Directions

1. Measure: Break or cut off the amount you need.

2. Mix: Twist and knead until color is uniform (about 1 minute). Stop once uniform—over-kneading can reduce tack from skin oils.

3. Apply: Press firmly into cracks/holes. For pipes, form a full cuff around the circumference.

4. Hold: Set the piece in place and do not overwork—bonds form immediately.

5. Prep tip: Clean and roughen surfaces for best adhesion.

6. Underwater tip: Use the polyethylene wrapper to keep putty from sticking to fingers.

7. Finish: After set, you can drill, file, tap, sand, machine, or paint.

8. Aftercare: Wash hands with soap and water.
   Not recommended for polyethylene or polypropylene plastics.
