Astral Bondset – White Epoxy Putty (Leak Repair & Sealing)

Astral Bondset Sanitary Underwater: White Epoxy Putty for Plumbing & Wet Repairs

For repairs requiring hygiene and a clean white finish—especially in bathrooms, kitchens, and wet areas—Astral Bondset Sanitary Underwater is the specialized solution. This is a two-component (2K) epoxy putty designed for permanent, structural repairs to sanitaryware, tiles, pipes, and concrete. Its unique formulation allows it to bond and cure effectively even underwater, making it indispensable for leaks and repairs where drying the surface is impossible.

Astral Bondset Sanitary Underwater cures to a bright white, non-yellowing solid that is resistant to mold and mildew. This makes it ideal for restoring chipped basins, fixing loose tiles, sealing cracks near drains, or repairing ceramic parts where a clean aesthetic is required.

• Sanitary Finish (White): Cures to a smooth, bright white finish that blends seamlessly with ceramic, porcelain, and white sanitary fittings.
• Structural Strength: Provides a durable, rock-hard repair that can be sanded, drilled, and painted once fully cured.
• Water & Mold Resistance: Forms an impermeable seal that protects against water damage and resists common mold growth in bathrooms.

How to Use Astral Bondset Sanitary Underwater

1. Preparation: Clean the surface thoroughly—it must be free of grease and loose debris. Lightly roughening the area with sandpaper improves bonding dramatically, especially underwater.
2. Mixing: Cut off the required amount. Knead the two components (resin and hardener) together rapidly by hand until the color is uniform white (no streaks). You have 8-12 minutes to work.
3. Application: Press the mixed putty firmly onto the repair area, forcing it into cracks or holes. Shape and smooth the putty before it hardens. For underwater use, press firmly and hold until adhesion is felt.
4. Finishing: Once fully cured (24 hours), the area can be drilled, sanded, or painted. Learn more about effective epoxy repair techniques.

Q: Does the white color fade or yellow over time?
