Made by Cornish Lime using our Mature Lime Putty with coarse sands from our extensive stock range. Available in a mini bag nominal weight or polythene lined bulk bag. Our stock coarse putty mortars are CLM28 and CLM28 with fibre additions.

We won’t supply ready mixed haired mortars/renders as lime is a highly alkaline product and research has proven that this can very quickly degrade the hair. We only advocate the addition of hair immediately prior to the material being applied.

Non Stock Mortars

We can supply a wide range of premixed mortars, but because they can seperate if stored for long periods of time we only hold our bestselling mortars in stock. For non-stock mortars a half tonne minimum order is required, and price will vary depending on order quantity.

For comparison we have listed a selection of mortars made from currently available sands. Please get in touch on 01208 79779 if you are interested in finding out more.

Our current non-stock coarse mortars are: CLM11, CLM17, CLM24, CLM26, CLM27, CLM34, CLM48, CLM70, CLM74, CLM80, CLM90, CLM102.
