It is essential to use lime if you are restoring a building that was originaly constructed with lime.
Most modern building materials are made using portland cement, which is hard, rigid and impervious. Lime allows a structure to breathe - it is porous, and flexible. It allows water to escape the building. Any fine cracks which develop will self heal, as opposed to cement, which just cracks and lets water in.Building with lime is a process that is simple, yet needs understanding. Lime is a lovely material to use, it is very forgiving, and inexpensive. Once you understand the material, and how it works, using it within your home will become a pleasure.
