Can you put a patch over another patch to stop a leak in an above ground pool liner?

Yes, you can put a patch over another patch to stop a leak in an above-ground pool liner, but it's essential to ensure that the surface is clean and dry before applying the new patch. Using a patching material that is compatible with the original patch is crucial for a secure bond. However, for a more permanent fix, it's best to remove the old patch and properly clean the area before applying a new patch. Always follow the manufacturer's instructions for best results.
