Repair cracks, gaps, and broken fittings around your pool or spa with the Anderson A+B Epoxy Putty 9904K, a hand-moldable two-part compound that bonds to plaster, concrete, fiberglass, and acrylic surfaces. After mixing, the putty begins to set within 40-60 minutes and reaches full steel-hard strength in 12 hours. One of its standout capabilities is the ability to cure fully while submerged, so you can patch skimmers, main drains, and return fittings without emptying the pool. The compound holds its shape once applied with zero shrinkage or sagging, and after curing it accepts sanding, drilling, and paint for a professional-looking finish.

Key Benefits

• Multi-Surface Two-Part Compound: The 9904K bonds firmly to plaster, concrete, fiberglass, and acrylic, giving you one product for virtually any pool or spa repair surface.
• Rapid Set, Steel-Hard Finish: Working time of 40-60 minutes lets you shape the repair precisely, while a full 12-hour cure produces a bond as hard as steel for lasting durability.
• Underwater Curing Capability: Apply and cure this putty beneath the waterline, making it possible to fix skimmers, drains, and fittings without the time and expense of draining the pool.
• No Shrinkage or Sagging: The mixed compound stays exactly where you place it, maintaining its molded shape throughout the curing process for a clean, precise repair.
• Sandable, Drillable, Paintable: Once hardened, the cured epoxy can be finished with sandpaper, drilled for hardware, or painted over to blend seamlessly with surrounding surfaces.
