Clean reusable pouch. Skin barrier ring or paste. Soft wash cloth. Soap and water. Razor for shaving hair on abdomen.

Wash your hands with soap and water. Remove the paper backing from one side of the adhesive disk. Center the sticky side of the adhesive disk over the face-plate opening of the new pouch. Press the adhesive disk onto the face plate, making sure there are no wrinkles in the disk. Alternatively, you can put a thin layer of cement on the face plate of the pouch.
