✔ Waterproof Protection

Simply knead the clay and press into cracks or voids. Easily conforms to uneven edges and stays firmly in place after curing.
Once set, the surface becomes water-resistant and helps block odors, moisture, and air leaks—ideal for indoor sealing use.
Perfect for AC wall gaps, pipe pass-throughs, electrical boxes, cable holes, and cracked drywall—great for homes and RVs.
Ready to use straight from the pouch—just shape, press, and smooth. No drips, no mixing, and no cleanup needed.
Clean and dry the surface thoroughly.
Tear open a pack and take the desired amount of clay.
Mold it into shape and press it firmly into place.
Let it air dry for 3–5 days until fully solidified.
⚠️ Avoid contact with water before it's completely dry.
