I have solid wood internal fire doors around my house.
One of the doors sticks when trying to close it, and in an attempt to open it while it was jammed shut, a piece close to the latch chipped/splintered. Luckily it didn't completely come off so I was able to push it back into place, but if anyone attempts to close the door again, it will completely splinter off.
What's the best way of fixing this causing the least amount of damage in the process? Ideally it would not involve re-painting since it was sprayed by a professional and getting them back for a small job like this would be difficult.
Would some sort of wood glue work here? How would I get it into the crack without completely removing the chipped piece, if this is even possible?
