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. 



A natural Hydraulic Lime ideal for rendering, plastering, pointing and masonry mortars, grouting & lime washing.

Health & Safety

Singleton Birch NHL particles, if inhaled, can irritate the upper respiratory track. Avoid contact with eyes. Irritation and even injury can occur. When mixed with water, the paste obtained is highly alkaline. It can dry the skin and mucous membranes in the event of prolonged contact. If present, chromates can be dissolved by the water and this could cause allergic skin reactions in some hypersensitive individuals when exposed by lengthy and repeated contact. The basic components of NHL are common natural materials.


Singleton Birch NHL 5 is a dry powdered lime made by slaking quicklime from silaceous chalks.

This material is stronger and more durable with a faster setting speed. Suitable for use with dense materials, exposed masonry and marine construction.
