A 25kg bag will produce approximately 15 litres of mortar and fill roughly 1.2-1.5m² of joint at a 10mm depth or can lay roughly 25 standard bricks. 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 kiln-dried 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.
Supplied in 25kg polythene-lined and colour and batch-code paper bags for easy identification on-site and palletised for ease of transport, storage, and handling. FIBC tonne bags are also available.
