My leather couch is peeling,how can I fix it.
It's not real leather if peeling. Try gluing it back down and look on Amazon, I think they sell kits to repair faux leather. Good luck.
Try Plasticote Paint (sorry spelling may not be quite right). Otherwise not sure what you could do accept reupholster or stretch covers. good luck!
Kelli is right that if it is peeling, it is not genuine leather. It is most likely bonded leather. Bonded leather cannot be repaired the same way as real leather can.
Many people have had luck with painting leather and leatherette products using a chalky based paint.
