Cracked rock lath w/ plaster
We have a 1940 farm house, walls & ceiling are Rock lath with a plaster skim coat.
Ceiling in the dining room has crack from one side to the other. I just removed the popcorn and old repairs (NOT DONE BY ME) It was paper tape w/ some compound to fill & smooth.
Crack is maybe 1/8 inch in spots with the crack going thru the rock lath. I know how to "V" the crack and clean it out but my question is exactly what compound do I use to FILL it. I do not want this coming back. Can not detect any movement in the rock lath when I push on it.
I read DURABOND or gypsum/sand plaster. Confused. Anything I can get from Home Depot to do this?
Thank you so much, Kathy
