Our house is about 150 years old (maybe older) and we decided to remove the old 'plaster' to reveal the stones. The plaster was, i assume lime based with sticks, hair and small stones. I have roughly got rid of the loose stuff but I'm after advice about the next steps. Do I clean off the stones with brick acid or soapy water? Do I use a stone enhancer? How do I seal it to stop it constantly crumbling. Any advice welcome
