Hi, I'm new to this site. Not a painter, just part of Physical Plant in a Physician's Clinic and do autocad drawings, select finishes, etc. We have a building that is 20 years old. All the millwork has been stained and sealed. It's not even a pretty stain. Everyone here is convinced it would take months to paint over it and then it might not stick. Anybody ever done this? What's the process?
