Good value, takes time to harden
Works well for filling small holes in the bathroom wall. Just remember it stays soft for a couple of hours, so don't touch it right after applying. Once set, it's very solid.

Saved me from a leaky pipe
Had a minor drip under the sink where the pipe meets the wall. This clay sealed it up perfectly. It's white so it blends in nicely with my tiles too.

Excellent weather resistance
Applied this to an exterior wall crack before the rainy season. It has held up perfectly through heavy storms without cracking or washing away.

Perfect for AC gaps!
I used this to seal the gap around my window AC unit. It was incredibly easy to mold by hand and stopped the draft immediately. No more bugs coming in!

Easy to use for DIYers
No mixing required! Just take a chunk, knead it, and press it into the hole. Great for someone like me who isn't handy with traditional spackle.

Effective but messy hands
The product works exactly as described for sealing drain pipes. My only complaint is that it can get a bit sticky on your fingers while applying, but water cleans it off easily.
Q: How much area does one 300g pack cover?
A: One 300g pack can typically fill approximately 10-15 standard AC hose holes or about 2 linear feet of narrow cracks, depending on the depth of the application.
Q: Will this stick to wet surfaces?
A: For best results, the surface should be clean and dry. While it has some adhesion to damp surfaces, applying it to a dry area ensures the strongest waterproof bond.
Q: Can I reuse the clay if I take it out of the package?
A: Yes, as long as you keep the remaining clay in its original airtight packaging or a sealed bag, it will remain pliable for future use until its shelf life expires.
Q: Can this be painted over once it dries?
A: Yes, once the sealing clay is fully cured (after 24 hours), it can be painted over with standard latex or oil-based paints.
Q: Is this safe to use on drinking water pipes?
A: This product is designed for external sealing and leak prevention on drain pipes and walls. It is not certified for direct contact with potable drinking water inside the pipe.
