Cornerstone Promix Traditional Basecoat Render

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

Promix Traditional Basecoat suits various rendering or plastering applications, including coarse render coats, dubbing out, scat coats, scratch coats and float coats within an appropriate render system. We recommend Cornerstone Promix Bonding Coat as a coarse basecoat for challenging high or low suction backgrounds. For a slightly finer, white and more contemporary finish we recommend our Cornerstone Promix Coarse 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.

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.

Do not use in temperatures below 5°C or above 30°C, or if freezing conditions are predicted within the following few weeks, including wind chill. We always advise following best practices for curing and protecting fresh lime renders and plasters. Protect from adverse environmental conditions, including frost, rain, direct sunlight and drying winds.
