In this episode of Talking Conservation, we explain the different types of lime used in building and restoration work. If you have ever wondered what the difference is between air lime, natural hydraulic lime (NHL), pozzolans, or hybrid lime mixes, this video will give you a clear introduction.
Understanding the types of lime is essential before starting any work on older or historic buildings. Whether you are a homeowner, builder, surveyor or anyone dealing with traditional construction, choosing the right lime can make a big difference to the long-term condition of the building.
We cover:
What air lime is and how it works
How pozzolans change lime chemistry and performance
What makes a lime hydraulic and how NHLs are classified
The role of hybrid mixes, including hot lime and insulating lime plasters
The importance of matching materials to traditional buildings
This is the second video in our lime series. In the next episode, we will discuss how to select and apply the correct lime type for specific jobs including pointing, rendering, plastering and flooring.
