A 20kg tub yields approximately 10 litres of wet lime mortar or render. For rendering, this covers roughly 1m² at a 12.5mm thickness. For brickwork pointing, this will fill roughly 1.2m², for stonework pointing 1m² at 25mm depth or bedding 0.5m².
Consumption rates will change based on the condition of the background and suction. The width and depth of the joint will influence this estimation. On-site trials are advised for the best yield indication for your specific project.
As natural products, our natural sands may exhibit variations in colour, texture, and shape. While these variations are minimal, when colour consistency is crucial, we strongly advise each elevation is completed using material from the same batch.
