More about Promix Traditional Basecoat Render & Plaster
Cornerstone Promix Traditional Basecoat is a dry ready mixed lime render and plaster designed as a coarse basecoat or float coat within an appropriate render system. Available in the colour buff.
Engineered with precision, using 100% pure natural hydraulic lime, natural sands, and conservation-appropriate additives to create a high-performance render and plaster. Enhanced plasticity supports a decreased likelihood of slump and improved adhesion. Further, a longer open time makes this render straightforward to apply, level and finish. Available as standard with Saint-Astier® NHL2 or NHL3.5.
Well-suited for projects looking for an attractive traditional textured finish.

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 Promix Coarse 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 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-coded paper bags for easy identification on-site. 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.
Store in covered and dry conditions, protected from environmental conditions, including water, damp or frost and clear from the ground. Always reseal packaging if product is still present.
Always read the available documentation before use. See the Download Documentation section below for more detailed product information, application guidance and datasheets.
