Preparation of skin Barrier/Wafer: 1. Measure your stoma using the measuring guide provided. Select a skin barrier With a flange (white ring) at least 0.5 in. larger than your stoma size. For flush or retracted stomas, convex skin barriers are recommended. 2. Trace the exact same stoma size onto the center white release paper on the back of the skin barrier. 3. Cut along the tracing With a curved scissor. * if using a pre-cut wafer, no cutting necessary. Convatec skin barriers are available in stomahesive and durahesive, solid and flexible With or Without convexity. 4. Acaulking material such as stomahesive paste or an eakin cohesive seal, can be applied to the back of the skin barrier to further fill gaps between the wafer and the stoma. Allow the paste to set for one minute prior to application to the skin (Do not spread the paste.) Application of skin Barrier/Wafer: 5. Center the skin barrier over the stoma. press the skin barrier against the skin if using a tape bordered skin barrier, remove the remaining backing paper one side at a time. 6. During application, maintain gentle pressure on the skin barrier for 30seconds to improve adhesion. Removal of skin Barrier/Wafer Gently pull the skin barrier down, away from the skin, while supporting the adjacent skin with your other hand. To assist with the barrier removal, an Allkare Adhesive Remover wipe may be used to remove any adhesive buildup.
