Topic Explanation:
The discussion revolves around finding effective methods to waterproof the glue wafer and tape collar of an ostomy appliance, particularly for activities involving water like swimming, snorkeling, or using a hot tub. The original poster, who uses a two-piece urostomy system, currently uses High Tape, a waterproof tape, but experiences issues with moisture retention and skin irritation upon removal. They are seeking alternative solutions or improvements to their current method to enhance comfort and appliance reliability during water activities.

Advice and Helpful Insights:
1. Alternative Wafers and Tapes:
- Consider using wafers without a tape backing, which are often more water-resistant. Major brands like Coloplast, Hollister, and Convatec offer tape-free wafers that might provide a better solution. For instance, Convatec has the Durahesive wafer, and Hollister's New Image line includes options without tape.
- Contact these companies directly to request samples and get advice tailored to your specific needs, often provided by a registered nurse.

2. Skin Protection and Extended Wear:
- Apply a skin prep solution on the tape portion of the wafer, allow it to dry, and then apply a second coat. This method can help extend the wear time of the tape and protect the skin.

3. Using Transparent Medical Tapes:
- Explore using clear medical tapes like Tegaderm, which are thin, transparent, and adhere well to the skin, providing a waterproof seal over the ostomy appliance. Tegaderm is easy to remove and gentle on sensitive skin, making it suitable for frequent changes.
- Tegaderm comes in various shapes and sizes and is used for multiple medical purposes, including dressing wounds and securing IV cannulas. It can be found online and is available in different regions, including the US and Canada.

4. General Advice:
- Keep experimenting with different products and combinations to find what works best for your specific needs, as individual experiences with ostomy appliance security and skin sensitivity can vary widely.
