Hi

I've a external toilet and outhouse that im going to be taking down which will expose a old granite (plus random other stones) wall, I've noticed the old mortar is very crumbly and dusty so i expect it wash away with rain if i dont render or plaster the wall.

Does anyone have any knowledge on the best way to do this ?

thanks
