Ostomy Paste vs Barrier Ring: Which One Should You Use for Leaks?
Quick Answer: Paste Fills Small Gaps, Rings Create a Wider Seal
- Ostomy paste works more like a filler. It can help fill small creases, dips, or gaps between the stoma and the skin barrier. It is not glue.
- Barrier rings create a wider, moldable seal around the stoma. They may be helpful when the skin is uneven, output seeps around the barrier opening, or a larger sealing area is needed.
Start Here: Check Where the Leak Starts
Before choosing paste or a barrier ring, remove the pouching system and look at the back of the skin barrier. The leak mark can show where output first moved under the wafer.
| What You Notice | What It May Suggest | What to Consider First |
|---|---|---|
| Leak starts from one small spot | A small crease, dip, or tiny gap | Ostomy paste may help fill the gap |
| Output seeps around the inner opening | Wider sealing issue around the stoma | A barrier ring may help create a broader seal |
| Skin is exposed around the stoma | Barrier opening may be too large | Re-measure and re-cut the barrier first |
| Skin has folds, scars, or dips | Barrier may not sit flat | A ring, paste, strip, or different system may be needed |
| Output is loose or liquid | Seal may break down faster | A stronger seal or shorter wear time may help |
| Skin burns, itches, or breaks down | Leakage may already be irritating the skin | Change the system and reassess the fit |
UOAA recommends checking the underside of the barrier for signs of stool or urine leaking underneath. If leakage marks are present, extra paste or a barrier ring may be needed in those areas.
Ostomy Paste vs Barrier Ring: Key Differences
| Decision Point | Ostomy Paste | Barrier Ring |
|---|---|---|
| Main purpose | Fills small gaps and creases | Creates a wider seal around the stoma |
| Texture | Soft paste from a tube or strip paste | Moldable ring or seal |
| Best for | Small dips, creases, or minor uneven areas | Uneven skin, wider gaps, frequent seepage near the opening |
| Application area | Around the cut edge or at the stoma base | Around the stoma or on the back of the barrier |
| Common mistake | Using too much | Stretching too much or leaving the opening too large |
| Important note | Not glue | Not a fix for a poorly cut barrier |
WOCN states that ostomy paste can be used as a filler for small uneven areas and creases, but it should not be used as glue and should only be used in small amounts.
When Each Product May Help More
Ostomy Paste
Ostomy paste may help when the skin is mostly flat but has a small uneven area that prevents the barrier from sitting smoothly.
It may be useful when:
- There is one small crease near the stoma.
- A tiny dip causes leakage from the same spot.
- The cut edge of the barrier needs a little filling.
- The skin surface needs light smoothing before the wafer is applied.
- You only need a thin bead of filler, not a full ring.
Use paste sparingly. Too much paste can interfere with a good pouch seal, and heavy output may wash paste away more easily.
Barrier Ring
A barrier ring may help when the pouching system needs a wider, more flexible seal.
It may be useful when:
- Output seeps around the inner edge of the barrier.
- The skin around the stoma is uneven.
- There are folds, scars, or dips near the stoma.
- The stoma opening is difficult to seal with the wafer alone.
- You need a moldable product that can stretch or shape around the stoma.
UOAA describes barrier rings and strips as products that can fill uneven skin surfaces, improve adhesion, and seal gaps between the stoma and the wafer.

How to Apply Each Product
Ostomy Paste
Goal: fill small gaps without creating a bulky layer.
|
Basic steps
|
UOAA notes that paste may be applied to the cut edge of the wafer or directly to the skin at the base of the stoma.
Practical tip:
If paste feels messy, apply less than you think you need. It is meant to fill gaps, not replace adhesive.
Barrier Ring
Goal: create a closer, more flexible seal around the stoma.
Basic steps
|
UOAA states that barrier rings may be applied to the back of the wafer or placed on the skin at the base of the stoma. Rings can also be broken apart or molded into a narrow piece when only part of the ring is needed.
Practical tip:
Do not overstretch the ring. If the ring becomes too thin, it may not fill the gap well.
Common Mistakes That Can Make Leaks Worse
Ostomy Paste
- Using paste as glue
- Applying too much paste
- Applying paste on wet or oily skin
- Using paste to cover an active leak
- Ignoring a barrier opening that is too large
- Reapplying paste repeatedly without changing the pouching system
Paste works best as a small filler. If you need a large amount every time, the pouching system may need reassessment.
Barrier Ring
- Stretching the ring too thin
- Leaving the center opening too large
- Applying the ring on damp skin
- Using a ring without checking the barrier cut size
- Stacking multiple products without a clear reason
- Assuming a ring can fix every leak
A barrier ring can support the seal, but it cannot fully correct a wafer opening that does not match the stoma shape.
Both Products
Avoid patching an active leak. If output has already moved under the barrier, the pouching system should usually be changed instead of covered with tape, more paste, or extra layers.
WOCN advises changing the pouching system at the first signs of leakage and not trying to patch it with tape because leakage can cause skin irritation and odor.
When Paste or a Barrier Ring Is Not Enough
Paste and barrier rings are helpful accessories, but they are not the main solution for every leak. If leakage continues, the full pouching system should be reassessed.
1. Recheck the Barrier Fit
The opening may be:
- Too large
- Too small
- Cut in the wrong shape
- Not centered around the stoma
- No longer matching the current stoma size
Stoma size can change, and WOCN notes that the pouching system opening may need to be changed when the stoma size changes.
2. Check Skin Shape and Output
Leaks may also happen because of:
- Skin folds
- Scars
- Dips or creases
- A flat or retracted stoma
- Loose or liquid output
- Sweating or oily skin
- Weight changes
- Changes in abdominal shape
If the skin surface is not flat, paste or a barrier ring may help smooth the area. UOAA notes that rings or paste can be used to make the skin surface flatter around folds, creases, or scarred areas so the wafer can seal well.
3. Contact a Stoma Nurse if Leaks Continue
Ask a stoma nurse or healthcare provider for help if:
- Leaks happen soon after every pouch change.
- The same area leaks repeatedly.
- The pouch will not stay on as long as usual.
- The skin stays red, wet, painful, or broken.
- You feel burning or itching under the barrier.
- The stoma has changed shape, height, or size.
- You are unsure whether convexity, a belt, paste, or a ring is appropriate.
WOCN notes that itching or burning under the pouching system may indicate leakage, rash, or infection, and recommends removing the pouching system as soon as possible to check the skin.

Why Does My Ostomy Barrier Gap When I Sit or Move?
Frequently Asked Questions (FAQ)
Q1: Is ostomy paste the same as glue?
No. Ostomy paste is not glue. It is used as a filler for small gaps, creases, or uneven areas. Using too much may interfere with the pouch seal.
Q2: Can I use both paste and a barrier ring?
Sometimes, yes. Some people may need both, but adding more products is not always better. If you need multiple layers every time, the pouching system may need a better fit.
Q3: Should I use paste or a barrier ring for liquid output?
Liquid output can weaken the seal faster. A barrier ring may provide a wider seal, but the best choice depends on the stoma height, skin shape, and where the leak starts.
Q4: Can a barrier ring stop all leaks?
No. A barrier ring can help improve the seal, but it cannot fully fix a barrier opening that is too large, too small, or poorly matched to the stoma shape.
Q5: Why does my skin burn after applying paste?
Some ostomy pastes contain alcohol and may sting on open or irritated skin. WOCN notes that some pastes can cause burning if used on open skin.
Q6: Should I add more paste if my pouch starts leaking?
Usually, no. If output has already moved under the barrier, change the pouching system and check the cause of the leak instead of patching over it.
