i feel the pain. i just finished a honey do project last week.
what started as repairing a crack in a 100+ year old house with mortar and lathe ended with an ice cream bucket of broken mortar on the floor and a whole bunch of swearing. the mrs. tellin me maybe i needed to call a pro didn't help.
in the end, it got fixed , repainted and my college student son switched his stuff in there.
of course that left a semi open room to work on. fortunately no big issues in that one.
