What is hydraulic lime?

Hydraulic lime sets by a process called hydrolysis, a reaction caused by water.  They are faster setting than non hydraulic limes and more durable, meaning they are well suited to use external use, especially in damp or exposed conditions.  There is more information about the differences between hydraulic lime and non hydraulic lime in our WHICH LIME? user guide.

Hydraulic lime is sold as a bagged powder, which means that it is mixed and applied in the same way as a modern cement. It is available in differing degrees of strength, classified as feeble hydraulic, moderately hydraulic and eminently hydraulic.

How do I mix hydraulic lime?

A standard drum mixer can be used to mix hydraulic lime, although a roller pan or paddle mixer is prefereable for larger projects.

In an empty mixer, add 1 part sand, followed by 1 part lime and then 2 parts sand.  Mix dry for at least 5 minutes.  Gradually mix in the water until the required consistency is reached. Mix for a further twenty minutes.  There are more details in our HOW TO MIX HYDRAULIC LIME user guide.

Or have a look at our User Guide PLASTERING WITH HYDRAULIC LIME for more information.
