If you have been using the paste/seal, I would continue doing that. It will add another layer of protection so that the skin has a chance to heal. I use a strip of an Eakin Seal that I cut off of the disk and apply kind of like you would apply paste... I stick the ES to the back of the flange (the sticky side), around the hole you've cut out for the stoma. Press it securely in place around the hole of the flange. Apply as usual. Best of luck to you. Is this your first attempt with convex wafers?
