Knocked off a load of plaster to uncover damp stone walls, mortar crumbling quite severely. Just wondering if there's a chance knocking off more plaster could compromise the wall's structural integrity? The wall was solid before removing the plaster, no cracks/signs of movement. Here's a pic of the exposed stone:
The plan is to apply a damp proof membrane to the damp wall, so is the best approach to continue taking off all the loose plaster and re-pointing using a standard sand/lime/cement mix?
