Hi there, thank you for your review. I'm so sorry to hear that your paint did not dry to the hardness you expected. Our Premium Plus Paint cures to its full hardness in about 4 weeks. Please note that humid temperatures can slow down the drying process. In the meantime, we recommend being gentle on the coating to avoid any abrasions or touch-ups. Once cured, the paint will provide the proper durability and protection. To fix the affected spot, I recommend sanding to remove the loose coating. Then make sure the area is clean and dry before touching that up. If needed, recoat the chair arm for uniformity. Customer satisfaction is important to us, and we appreciate your feedback. Please reach out to us directly if you need further assistance; our Customer Care team is happy to help! -Lina
