Lime, Hydraulic or Non-Hydraulic? Conserv®

Lime, Hydraulic or Non-Hydraulic? Hydraulic lime sets by hydrolysis whereas non-hydraulic lime sets by carbonation. The hydraulic lime can set underwater, that's because hydrolysis is a reaction caused by water. The non-hydraulic lime needs air to carbonate and thus set. In physical terms, the two materials are very different to work with.

Different Types of Lime Mortar Explained DoItYourself

Non-hydraulic Lime Mortar. Non-hydraulic lime is so named because it does not require water in order to harden. This type of lime is basically taken from calcium carbonate in its purest forms, i.e. limestone and chalk. The material is burned in a kiln and made to produce quicklime or calcium oxide.

Allow 30 minutes for a natural hydraulic lime mortar compared to up to a week for lime putty mortar. Pre-mixing is obviously unnecessary when purchased as a ready to use mortar. When you’re ready to carry out the work, the mortar is “knocked up” (agitated/mixed) immediately prior to use to plasticise the mix and help to reduce shrinkage.
