Overhead water tanks, wash basins and plumbing joints are often prone to leakage due to cracks, aging fixtures, water pressure and temperature variations. Left untreated, even a minor leak can lead to water wastage, structural damage and increased maintenance costs. The simplest and most effective solution is using a fast-setting epoxy putty—a ready-to-use bonding material that seals leaks instantly and permanently.
Bondset Fast Setting from Astral Adhesives is engineered as the best epoxy for water leaks, offering unmatched adhesion, quick curing and long-lasting waterproofing.
Why Epoxy Putty Works Best for Plumbing & Sanitary Repairs
Epoxy putty is a two-part adhesive that, once kneaded, transforms into a rock-solid compound capable of bonding metals, ceramics, concrete and PVC. Its unique properties make it ideal for sealing overhead tanks and wash basins.
1. Strong Waterproofing Ability
A high-quality waterproof putty for pipes must withstand constant water flow and pressure. Epoxy putty creates a watertight seal that resists moisture penetration.
2. Fast Setting Time
Bondset Fast Setting cures within minutes, allowing you to restore function quickly without dismantling the plumbing system.
3. Works on Wet or Damp Surfaces
Unlike many adhesives, epoxy putty adheres strongly even when the surface is slightly moist—perfect for emergency plumbing repairs.
4. Multi-Surface Compatibility
It bonds effectively with:
- Metal pipes
- Overhead tank walls
- Ceramic wash basins
- PVC joints
- Cement surfaces
- Water lines and elbows
5. High Strength & Durability
Once cured, the putty becomes extremely hard and impact-resistant. This makes it perfect for long-term sealing.
How to Seal Overhead Tanks & Basins Using Epoxy Putty?
Step 1: Identify the Leak
Inspect the overhead tank, wash basin trap, joints or pipe connections to locate the exact leakage point.
Step 2: Prepare the Surface
Clean the area by removing dirt, algae, loose particles or rust. A clean surface improves adhesive strength.
Step 3: Cut & Knead the Putty
Take required quantity of Bondset Fast Setting and knead it until the color becomes uniform. This activates the curing process.
Step 4: Apply the Putty on the Leak Area
Press the putty firmly into the crack, hole or gap. For overhead tanks, apply from inside or outside depending on accessibility. For wash basins, apply around the crack, trap joint or under the basin.
Step 5: Smooth & Shape
Use wet fingers or a tool to shape the putty neatly. This improves sealing and aesthetics.
Step 6: Allow It to Cure
Bondset Fast Setting hardens within 5–10 minutes and fully cures in 1 hour. Once cured, the surface becomes completely waterproof and ready for use.
