How to mix lime mortar
Here is our instructional video showing you how to mix lime for mortar.
We recommend using approximately 1 part lime to 3 parts sharp sand. We used Singleton Birch NHL 3.5 for this project, and the mortar was used for building a small wall.
Which lime should I use?
Depending on the purpose of the mortar, different limes are usually used. We used a Natural Hydraulic Lime, with the strength 3.5 (known as NHL 3.5), on this particular project which is ideal for re-pointing and building walls. NHL 2 is weaker, generally more flexible & sets slowly, which is ideal for internal applications or where conservation is a primary concern with soft or deteriorating stones and bricks. NHL 5 is stronger and has a faster set, which is primarily used for granite, engineering brick, basalt, flint, paving, roofing and chimneys.
