What Is Ostomy Paste and How Do You Use It?

What is ostomy paste?

Ostomy paste is a moldable material used to fill in small gaps and uneven areas between your stoma and the skin barrier (wafer). It acts like a “caulk” or filler rather than a glue, helping to create a smoother surface so your ostomy appliance can seal more effectively and reduce the risk of leaks.

Most ostomy pastes are made from hydrocolloid materials designed to be skin-friendly and to absorb a small amount of moisture. They are available in traditional tubes, strips, or pre-formed shapes, giving you options depending on your stoma, skin contours, and personal preference.

What is the purpose of ostomy paste?

The main purpose of ostomy paste is to help create a better seal and protect the skin around your stoma.
When your peristomal skin (the skin around the stoma) is uneven, scarred, or creased, paste can fill in those tiny gaps and prevent output from sneaking underneath the barrier.

By improving the fit of your appliance, ostomy paste may help:

• Reduce leakage and unexpected pouch changes

• Protect irritated or at-risk skin

• Extend wear time in some cases

• Improve comfort and confidence in daily activities

Paste is one tool in a larger toolkit of ostomy products; it works best when combined with a well-fitted barrier and good skin care habits.

When should you use ostomy paste?

You might consider using ostomy paste if:

• Your stoma is irregularly shaped or sits slightly above/below the skin surface

• You have dips, scars, folds, or creases near the stoma

• You notice recurring leaks in the same area under your barrier

• Your skin barrier does not sit flush against your skin despite careful sizing and application

Many people start using paste after discussing leaks or irritation with a Wound, Ostomy, and Continence Nurse (WOCN) or other ostomy specialist. If you are unsure whether paste is right for you, a clinician can evaluate your stoma, skin, and current appliance to recommend the best approach.

When might ostomy paste not be necessary?

Not everyone needs ostomy paste. You may not need it if:

• Your peristomal skin is flat, smooth, and free from scars or deep folds

• You have a well-fitting barrier that seals securely and rarely leaks

• You are already using a barrier ring or another product that adequately fills gaps

In some situations, relying only on paste can mask an underlying fit problem. If leaks continue even with paste, it may be more effective to adjust the barrier size, shape, or type rather than adding more paste. If you have open wounds, severe irritation, or a history of skin allergies, consult a clinician before using paste or any new product.

Types of ostomy paste

There are several forms and formulations of ostomy paste, each with advantages depending on your needs:

• Traditional tube paste
  A soft, toothpaste-like paste that you squeeze directly from a tube.
  It’s easy to apply as a thin bead or dot where you need it.

• Strip or “stoma” paste
  Paste formed into strips or sticks that you can break off, roll, and mold into shape.
  This is helpful if you prefer working with a more solid form rather than a tube.

• Alcohol-containing and alcohol-free formulations
  Some pastes contain alcohol and may cause a temporary stinging sensation on irritated or broken skin.
  Alcohol-free options are available for those with sensitive or already irritated skin.

Different brands may vary in texture, firmness, and how easily they spread or mold. If one type doesn’t feel comfortable or easy to use, another brand or format may be a better match.

How to apply ostomy paste (step-by-step)

Always follow the instructions provided with your specific product and any guidance from your clinician.
The general steps below offer a helpful starting point:

1. Prepare and clean the area
   Gently remove your existing pouching system. Wash the skin around your stoma with warm water (and a mild, recommended cleanser if advised) and pat thoroughly dry.

2. Inspect your skin and stoma
   Look for any redness, open areas, or changes in your stoma. If you notice new or worsening problems, contact your ostomy nurse or healthcare provider.

3. Cut or size your barrier
   Cut the opening of your skin barrier to fit closely around your stoma, leaving only a small gap. A closer fit reduces the amount of paste you need.

4. Apply the paste

   • Tube paste: Apply a thin bead of paste around the opening of the barrier or directly to the skin where you see dips or gaps.

   • Strip paste: Tear off a small piece, roll it between your fingers, and press it into the areas that need filling.

   Use only enough paste to fill spaces; more is not always better and can make cleanup harder.

5. Allow a brief set time (if recommended)
   Some pastes work best if you let them sit for a short time to firm up slightly. Check your product instructions for specific guidance.

6. Apply the barrier and pouch
   Place the barrier over your stoma and press gently but firmly around the opening for several seconds to help ensure a good seal.
   Attach your pouching system according to the manufacturer’s instructions.

7. Check for comfort and seal
   Make sure there are no obvious gaps and that the appliance feels secure. If you feel burning, itching, or ongoing leakage, remove the system and consult your healthcare provider.

Common mistakes when using ostomy paste

A few simple adjustments can improve results and protect your skin:

• Using too much paste, which can make removal difficult and does not always improve the seal

• Applying paste to damp or oily skin, which can weaken adhesion

• Using paste as a substitute for a properly fitted barrier or for professional assessment of frequent leaks

• Ignoring persistent irritation, which should be evaluated by a clinician

If you encounter ongoing problems, it’s better to seek guidance than to continually increase the amount of paste you use.

How to remove ostomy paste

Ostomy paste is designed to come off when you remove your barrier, but some residue may remain on your skin.
To remove it comfortably:

• Gently peel away your barrier and pouch, avoiding sudden pulling or tearing

• Wipe away remaining paste with a soft cloth or disposable wipe and warm water

• Use only ostomy-safe adhesive removers if recommended by your clinician or product manufacturer

• Avoid harsh scrubbing or strong soaps that can damage or dry your skin

Your goal is to clean thoroughly without irritating already sensitive skin.

Alternatives and complements to ostomy paste

Depending on your anatomy and skin condition, your clinician may suggest other options that work alone or together with paste:

• Barrier rings (pre-formed hydrocolloid rings that can be stretched or molded around the stoma)

• Convex barriers to help a retracted or flush stoma protrude into the pouch

• Different barrier shapes and sizes to better match your body contours

• Flexible or moldable barriers designed to adapt to uneven surfaces

Often, a combination of the right barrier plus a small amount of paste or a ring provides better results than any single product used alone.

Frequently asked questions about ostomy paste

Is ostomy paste safe for sensitive skin?
Many ostomy pastes are formulated for sensitive skin, and alcohol-free options are available. If you have a history of allergies or skin reactions, check ingredients and talk with your clinician before using a new product.

Can I use ostomy paste with barrier rings?
Yes, many people successfully use both, but the combination should be guided by a clinician. In some cases, a ring alone may provide enough filling and support, making paste unnecessary.

How often should I replace paste?
Ostomy paste is removed and reapplied each time you change your pouching system. If you find yourself changing your appliance more frequently due to leaks, discuss this with your healthcare team.

Does ostomy paste extend wear time?
For some people, paste helps reduce leaks and can contribute to longer wear time. However, its main role is to improve the seal and protect the skin, not to force longer wear beyond what’s comfortable or recommended.

Ostomy paste can be a valuable tool in protecting your skin and helping your ostomy system perform at its best. If you are unsure whether paste is right for you, or if you’re struggling with leaks or irritation, consider consulting a Wound, Ostomy, and Continence Nurse or your healthcare provider. They can help you choose the right combination of products and techniques for your body and lifestyle.
