Cornerstone’s general purpose range of Lime mortars and renders, with St. Astier Natural Hydraulic Lime and selected sands to make a high performance, fully breathable NHL mortar.

Through the controlled addition of work aids, the Cornerstone Drymix range has been formulated to give improved workability, reduced risk of shrinkage and reduced water requirements.

Cornerstone’s Drymix mortars are batch blended for consistency, are naturally coloured with no pigment addition, and are available in a range of sands (CLD28 Coarse & CLD35 Fine) and binder strengths (NHL2 & NHL3.5) to give the desired finish, natural colour and mortar properties.

Finish: Drymix is available in two finishes. Coarse mortars (CLD28) are made with a coarse 5mm down sand, most commonly used for base coat applications.  Fine mortars (CLD35) are made with a fine 2mm down sand which can be applied thinner and are most commonly chosen for their fine finishes.

Binder: Drymix is held in stock in two binder strengths, NHL2 and NHL3.5. NHL5 mortars are available upon request. NHL2 is a weaker binder appropriate for softer stones and more heavily weathered surfaces; NHL3.5 is a moderate strength binder for more robust stonework.

Product is palletised for ease of storage, handling and warehousing and packaged in colour-coded and batch-coded 25Kg bags for ease of use and easy identification on site.

Products shown below are available ex-stock; should you require a sand or colour blend other than those below, please contact us to discuss so we can make it to order accordingly.


Cornerstone Drymix can be mixed with water to make a fully functional lime mortar.

Each project is unique, always seek professional advice before undertaking a project.
