Thanks for getting in touch.
If rendering/plastering over you could use our Walling Mortar – here’s a link to the product:
If you’re not looking to cover you could use either our CLD28 or our CLM28 which will both give a buff/biscuit colour and are made with our CLS28 sand. The CLM28 is made from lime putty and sand and is supplied as a wet product in a plastic bag, the CLD28 is pre-blended with sand and hydraulic lime and is a “just add water” product.
Please let us know if we can be of further help.
