This topic is about understanding how stoma powder affects the adhesion of ostomy appliances and learning the correct way to apply the powder. Here are some helpful tips and insights shared by others:

- Use sparingly: It's important to apply only a light layer of stoma powder. Too much powder can prevent the wafer from sticking properly. Dust on a thin coat, then gently brush, tap, or blow off any excess so that only a fine film remains.

- Only when skin is weeping or broken: Many people suggest using powder only if the skin around the stoma is damaged or weeping. If the skin is intact, it's best to avoid using powder, as well as soaps, creams, or ointments, which can interfere with adhesion.

- Crusting method for damaged skin:
1. Apply a light layer of powder and remove the excess.
2. Dab the area with a skin-prep or barrier wipe, such as 3M Cavilon.
3. Let it dry to form a thin "crust."
4. Apply the wafer. This method can protect the skin and improve adhesion, with some users experiencing a wear-time of 5-7 days.

- Alternative practice—light powder every change: Some people use a light dusting of powder at each change, even on healthy skin, for preventive protection. They still remove the excess powder and often skip the barrier wipes, following advice that modern wafers are gentler and don't require wipes unless the skin is irritated.

- Sequence example from a urostomy user:
1. Air-dry the skin after showering.
2. Lightly dust powder in two rings over a 5"×5" area.
3. Brush off the excess powder.
4. Spray a liquid skin barrier over the same area and let it become tacky.
5. Stretch the barrier ring to the size of the flange, keeping the outer plastic in place while pressing the ring to the wafer.
6. Apply the wafer and warm it with your hand for several minutes to secure the seal.

- Equipment/brands mentioned include Hollister, 3M Cavilon Skin Prep wipes/spray, generic barrier sprays, barrier rings, and two-piece appliances.

- Typical wear-time results reported are 5 days regularly, and up to 7 days in cooler, drier weather.

- Key reminders:
- Powder alone can reduce adhesion, so it's best to combine it with a barrier film or not use it if the skin is healthy.
- Always remove visible powder before applying the wafer.
- Warm the wafer or ring with your hand after application to enhance bonding.
