persnickety old paint
Our house is 30 years old and the orginal builder used exterior plastic epoxy paint (this has been determened by experienced old painters - they didn't know how to handle this either) on all interior trim and doors. We have tried sanding and using Zinzer 123 and like primers, but the new paint just peals off. We have also tried several paint removers and it will remove the new paint but will not touch the old paint. Have tried to sand off the old paint with a belt sander and circler sander, still won't come off, just gums up on the sandpaper. We are replacing most of the trim but the windows have to stay and we have about 18 solid wood doors with panels that we would like to keep because of replacement cost.
Any help would be appreciated. Would like to finish this project in my life time and time is getting short (63 and counting).
