Incorporating an appropriate proportion of hydrated lime into a cement-based mixture improves plasticity and workability, making the product easier to handle on the trowel. Hydrated lime also increases water retention, which helps to improve the contact and bond with the substrate.
Why Add Lime to Mortar?
Lime has been used as a binding material for centuries, even dating back to Roman times. It is an important mineral for making mortar and plaster, but why add lime to mortar?
Using lime in mortar provides a number of benefits, from providing a more robust and more durable mix to offering better weatherproofing. It also helps to reduce shrinkage and cracking and makes the mortar more resistant to water, which can be an issue in areas with high rainfall or humidity.
The main reason for using lime in mortar is that it provides an adhesive quality that helps the mortar to adhere more strongly to the surface it is applied to. This is especially important on surfaces such as stone, which is naturally porous and can be difficult to bond with other materials. Adding lime to the mix increases the adhesive quality of the mortar, allowing it to bond more securely with the surface.
One of the benefits of using lime in mortar is that it helps to reduce the amount of shrinkage and cracking. As mortar dries, it shrinks and cracks, which can lead to weakened structure and damage over time. Adding lime helps to reduce this shrinkage, allowing the mortar to remain stronger and last longer.
