Thank you for your feedback, The Door. We sincerely apologize about any confusion on the Masonite 36 in. x 84 in. No Panel Lincoln Park Primed Interior Sliding Barn Door Slab with Hardware Kit, Primed White @ The Home Depot. This door is not a prefinished door if you purchased it from this product page - it is primed only and does require paint on all 6 sides to maintain warranty. If you ever need assistance with finishing or installation, please feel free to let us know first before you continue as most issues can be cleared up with a quick conversation. We apologize again for the issues you have experienced, and if you have any additional questions, please don’t hesitate to contact us via email at helpline@masonite.com. Sincerely, Masonite
