A small hole or tear doesn't always mean you need a new pool liner. With a vinyl pool liner patch kit, you can often repair minor damage without draining your above ground pool.
Here's how to patch a pool liner, including underwater repairs.
Can You Patch an Above Ground Pool Liner?
Yes. You can often repair small punctures and tears with a vinyl patch kit designed for swimming pools.
Patching works best when the surrounding vinyl is flexible and undamaged. Large tears, separating seams, or brittle liners may require replacement.

What You'll Need to Patch a Pool Liner
LinerWorld's Perfect Patch Vinyl Repair Kit includes vinyl patching material and adhesive. Always follow the instructions supplied with your kit.
How to Patch an Above Ground Pool Liner: Step by Step
1. Locate and Clean the Damaged Area
Identify the hole or tear and gently clean the surrounding vinyl with a soft cloth. Remove dirt, oils, and debris that could interfere with adhesion.
Avoid abrasive cleaning tools or aggressive scrubbing.
2. Cut the Vinyl Patch
Cut a patch large enough to extend well beyond the damaged area. For LinerWorld's Perfect Patch kit, the existing instructions recommend a patch approximately three to five times the size of the hole.
Round the corners to reduce the chance of peeling.
3. Apply the Adhesive
Apply adhesive evenly to the patch, following your repair kit's instructions.
Use only adhesive designed for the patch material and the intended application, especially for underwater repairs.
4. Attach the Patch
For an underwater repair, fold the prepared patch with the adhesive protected as directed by the kit, then position it over the damaged area.
Press the patch firmly against the liner and smooth out trapped air.
For damage above the waterline, follow the kit's instructions for application to a dry or damp surface.
5. Apply Pressure and Monitor
Hold the patch firmly for the time specified by the manufacturer. LinerWorld's Perfect Patch instructions recommend applying pressure for about two minutes.
Allow the adhesive to set as directed, then monitor the repaired area and pool water level for signs of continued leakage.
Can You Patch a Pool Liner Underwater?
Yes, if your patch kit is designed for underwater use.
In many cases, you can repair a small underwater puncture without draining the pool. Avoid draining an above ground pool unless the manufacturer or a qualified professional instructs you to do so.
When Should You Replace Instead of Patch?
Consider replacing your pool liner when:
- The tear is too large for a reliable patch.
- Seams are separating.
- Multiple leaks keep developing.
- The vinyl is brittle, cracked, or deteriorating.
- Previous repairs no longer hold.
Patching can extend the life of a liner, but it cannot restore deteriorating vinyl.
If repair is no longer practical, browse LinerWorld's above ground replacement pool liners to find a compatible replacement.
Keep Your Pool Ready for Swimming
Inspect repaired areas periodically and maintain proper water chemistry to help protect your liner.
For small, isolated damage, a vinyl patch kit may save you the cost of a full replacement. When the liner is extensively worn or damaged, replacing it is often the better long-term solution.
