How do you remove old lime mortar? Using a pointing chisel to remove lime mortar is quite easy; the mortar is soft and breaks easily in front of the chisel. Portland-based mortars are quite hard, and hand-chiseling takes many blows from the hammer to remove just a couple inches of joint. This hard mortar is very damaging for brick and soft stone.

What is the difference between lime plaster and gypsum plaster? Lime sets slowly by absorbing carbon dioxide from the air, whereas gypsum plaster sets rapidly by crystallising (even fully hydrated gypsum plaster sets within about a day). Also, as a lime plaster dries it shrinks slightly, while a gypsum plaster expands.
