Promix Coarse Basecoat Render & Plaster - Natural Hydraulic Lime Mortar

Suitable for internal or external use, where the binder strength is appropriate for the host background or surface.

Cornerstone Promix Coarse Basecoat suits various render and plastering applications, including coarse render coats, dubbing out, scat coats, scratch coats and float coats.

For challenging backgrounds with very high or low suction, Promix Bonding Coat can be used as a coarse first coat, followed by a coat of Promix Basecoat on top. For a more traditional, slightly coarser and buff coloured finish, we recommend our Promix Traditional Basecoat. Appropriate for various project types, including conservation, renovation, or sustainable construction.

A 25kg bag yields approximately 15 litres of lime render or plaster and covers roughly 1.5m² at a 10mm thickness. Consumption rates will change based on how even the background is and suction. On-site trials are advised for the best yield indication for your specific project.

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.

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.
