What I'm doing now, because the convex and belt were causing a granuloma, is:
1: Washing the area with antibacterial dish soap and then conditioner just once, followed by moisturizing soap after that and after any spewing. I find antibacterial soap much less painful than alcohol or iodine for sterilizing the burns from infection, which causes weeping and separation from the paste.
2: Blow drying well and applying two coats of skin protectant (I use generic Flonase as it stops the stings).
3: Placing a ring of 50/50 cut moon barrier strips 1/2" away from the stoma and another coat of skin protectant around the stoma. This is designed to protect the skin from a blowout. It's expensive but works. Dry extremely well at this point, perform a finger test to ensure it's bone dry and not slippery or wet.
4: Applying olive oil-based lotion on scar tissue only, filling the belly button hole with toilet paper to level it, and placing thin cardboard strips over scar tissue and belly button hole. If not, the adhesive causes intense itching from grabbing it.
5: Precutting the wafer hole, weakening it horizontally for the belly fold.
6: Applying a ring of paste around the stoma and pressing down around it so it sticks to the skin. Put another ring of paste around the first one. Then remove the backing and cover the flat area of the wafer with yet another ring of paste. It takes about half a tube. 😆
7: Lining up and gently applying, pressing down around the stoma but not causing the paste to stick out much past the edge of the wafer hole. Barely have wafer flanges touching the skin. Press those into place. This creates a wall of paste with an elevated convex which, of course, needs more time to set up. But it's been protecting the granuloma.
8: I put extra-large barrier strips all around to secure the mess into place, then blow dry to heat activate. Then I lay and wait a few hours for the paste to set up.
It's kind of weird but it works, with 5 average day bag wear times usually. It's on solid and I don't have to use a belt, which was causing the granuloma issue. In fact, I was told to do this very thing by my ostomy supplier and we laughed because I was already doing it. 😆
So if I get a blowout, like the wall of paste fails for instance, there is this pouch area that catches it before getting all over the place.
The thing is though, it makes the area extremely stiff and sitting in a chair or driving (not straddling a toilet or stool) seems to cause stress issues from the paste on the skin, then leaks can occur or not. Sometimes they don't. I can't feel the difference so it's tough to tell.
At night, lying only on my back, everything is fine. It's when I get up and move around, sit in chairs especially, that aggravates it, causing the wafer to pop off or get irritated.
So I definitely need some sort of flexibility from both the skin adhesive material and the wafer. But the adhesive has to be very strong, so that only adhesive remover is going to budge it. So that all three; skin, adhesive, and wafer, move as one.
If I can accomplish this, I would then consider a two-piece with a lock (none of this Hollister click junk, I had to super glue theirs together as it was always parting).
So Hollister has a new flexible wafer, but it's a click two-piece which I would have to turn into a one-piece.
So now I need something like a flexible paste (no sting), similar to painter's caulk.
I was thinking of using painter's caulk on top of a thin layer of ostomy paste, but the set-up time could be many hours as it cures much slower.
So the problem I see now is the paste not being flexible. I tried rings and they just fail quickly, lacking sufficient adhesion strength.
Rings are too low for my needs, but I may try them if I can get the wafer to fit and flex with my belly fold. See if they are strong enough.
