The house was built in 1939. It has 18" thick stone walls, finished on the inside with plaster. There is no lath, it is a material that kind of looks like drywall with holes in it for the plaster to hold onto.
A roof leak (fixed) left a wall with a large hole. (6 feet by about 2 feet)
What would be the best way to fix this? The water did come down between studs, so there is good wood on either side of the hole. Is that board with the holes a good approach? I have done a lot of home repair and remodelling stuff but never had to fool with the walls before.
Any ideas are appreciated.
