In the past walls were rendered and plastered with lime. Lime is a truly wonderful material that can be bent to a whole series of uses, but as a render on stone it is unsurpassed. It ‘breathes’, allowing moisture to escape and suppressing damp walls. This is because it is very porous. So why are there damp walls in so many old houses today?
