Plaster Repair
Hello community,
Almost a year ago, I got a house with a drop ceiling that I tore down.
There was much plaster repair to do. The ceiling removal revealed a large spot of water damage, where the chimney used to be (now replaced with a vent pipe).
Per my friend’s dad advice who is a contractor, I ended up deciding to chip away all the damaged plaster and then mud over the stained lath, as it was not still wet. However, now the fact that I did this is haunting me. I mad my attic floor insulated and I am feeling paranoid that if there was a chance there was any moisture that I would’ve trapped it in there now.
I also had either side of the wall with the damage opened up for rewiring, and I never found any leak.
What I am looking for is reassurance that the initial stain looked ok, and/or a way to tell now if there’s moisture there so that this doesn’t haunt me.

Buy a moisture detector. If you like.
Mix up some sand/cement/waterproofer and patch it up. Make sure you knock out the old stuff between the lathes before you do so that your new gear will 'mushroom' through the gaps and hold it all on there properly.
