Lime has been used in buiding work since Roman times, but use declined in the 20th century. Recently it has had a resurgence in use, as it has been realised that modern materials can be damaging. It is important that lime is used in the restoration of period properties. This is also better for the environment. Simply put, lime render reacts with the CO2 in rainwater in a repeated cycle. It is converted back to calcium carbonate (the original limestone). This means that over the years, it gets stronger and harder. Here at K.E. Jones & Son Builders, we use lime from the Anglia Lime Company
