Leakmaster Quick Set Putty Single Stick for Underwater Leak Repair - Dries White | PQ501

The professional's choice for a fast-acting, underwater leak repair.

Product Overview

The Anderson Manufacturing PQ501 is a hand-moldable, single-stick epoxy putty engineered for rapid plumbing and structural repairs. Unlike traditional two-part systems that require measuring, this pre-mixed formula activates instantly when kneaded and hardens to a permanent seal in just minutes. It is specifically formulated to cure underwater, making it the ideal solution for sealing cracks in skimmers, main drains, and light fixtures without draining the pool.

Key Features

• Rapid Polymerization: The fast-setting epoxy chemistry cures in just 5 minutes to stop leaks instantly.

• Extreme Adhesion: Bonds aggressively to fiberglass, concrete, gunite, PVC, and ceramic, even while submerged.

• Underwater Cure: Engineered to harden fully below the waterline, allowing for immediate repairs without lowering water levels.

• Chemical Resistance: The cured epoxy resists degradation from chlorine and pool chemicals, ensuring a long-lasting, non-shrinking seal.

How to Use

Note that it is recommended by the manufacturer for the temperature of the item applied to (or water in contact) be above 50 degrees for the product to cure properly.

This product, once cured is inert and can tolerate low temperature water.  Works with both fresh and salt water pools.

1. Prep the repair area by removing loose debris, algae, or oils to ensure a strong bond.

2. Cut the desired amount of putty from the single stick.

3. Knead the material with your fingers until the color is uniform and the putty feels warm.

4. Apply firmly into the crack or void within 2 minutes of mixing, smoothing it over the edges.

5. Cure allow at least 5 to 10 minutes for the putty to harden completely before disturbing.
