About This

  • 【Easy to Mold & Instant Repair】 Our moldable sealing clay is designed for effortless application with no special tools or mixing required. Simply knead the soft, pliable putty with your fingers to shape it into any form—circular, square, or custom—to fit irregular gaps. It’s the perfect, mess-free solution for homeowners and DIY enthusiasts looking for a quick wall hole filler or pipe repair.
  • 【Multi-Purpose Sealing Solution】 This versatile waterproof sealant mastic is an all-in-one fix for your home. Use it as a duct seal putty for HVAC, a plumber’s putty for sink drains, or a wall putty to fill holes from air conditioning pipes and cables. It effectively blocks unwanted odors, and seals gaps in electrical boxes with its heat-resistant properties.
  • 【Superior Waterproof & Airtight Seal】 Formulated with a high-density waterproof repair sealing clay, it creates an indestructible barrier against leaks and moisture. Once applied, it cures into a firm, airtight seal that resists cracking, shrinking, and drying out over time. Whether indoors or outdoors, it stands up to temperature fluctuations, keeping your environment dry and protected year-round.
  • 【Professional White Finish】 Our sealing mud comes in a clean white color that blends seamlessly with most household walls for an understated, professional look. The slow-curing formula gives you ample time to smooth the surface for a neat finish. For best results, ensure the application surface is clean and dry; the clay will fully solidify into a sturdy, reliable seal within 3-5 days.
  • 【Stay Fresh with Resealable Bag】 Each pack features a built-in sealing bag so you can reseal it after every use, preventing waste and ensuring the clay stays soft. If the putty hardens, just heat it in the microwave for 20 seconds; it will become super soft and flexible again, perfect for hassle-free repairs.

    "Saved me from an expensive plumbing repair"

    I discovered a small leak under my kitchen sink late at night.

    This repair tape was incredibly easy to apply and stopped the leak immediately.

    It held securely until I could arrange a permanent repair.

    A must-have item for every homeowner.

    "Quick fix that actually works"

    I used this waterproof repair tape on an outdoor water pipe.

    The application took only a few minutes and the seal has remained strong through several rainstorms.

    It's durable, reliable, and much easier than I expected.

    I'm very impressed with the results.
