Can you install ledger stone to a painted drywall?

Installing ledger stone directly onto painted drywall is not recommended, as the paint can interfere with adhesion and may lead to the stone falling off over time. It's best to remove the paint or install a suitable backing material, such as cement board, to ensure a strong and lasting bond. Proper surface preparation is crucial for successful installation. Always consult product guidelines and, if necessary, a professional for the best results.
