Sealing chipboard prior to paint advice

[VeRetired]

I recently bought an internal door (factory primed) that I thought was solid pine but after taking 18ml off either side with a bench saw, it revealed a chipboard core. Although the raw chipboard is on the hinge side and not really noticeable it is not my way of doing DIY, but the man who was paid to hang it used a plane to take a little more off and it is rough to say the least. I have always done my own work in the house but ill health prevents me from doing my own home improvements.

My request for help is: I would like to build the edge up so it will take a coat of paint and look decent, so what is the best method and substance to use.
Thanks for all help.

plane it a bit more and stick on a door lipping

these are sold loose for that very purpose, and are not supposed to be fixed until you have finished cutting down the door.

Thanks JohnD I appreciate your advuice, but I was hoping for a solution that I would be able to manage. That is, without taking the door off, because they are pre-glazed and too heavy for me.

unfortunatle you have 2 choices take it off and do it properly

or fill and paint hoping the random grain movement wont be to obviouse

those sorts of doors are only supposed to have about 9mm knocked off
and 13mm is about the max for a "normal "door
