More about Promix Bonding Coat Render & Plaster
Cornerstone Promix Bonding Coat is a dry ready mixed lime render designed for challenging backgrounds as a bonding coarse coat or the last coat for a highly textured finish. 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. 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 with fibres for use on multiple backgrounds in the absence of mesh. Available as standard with Saint-Astier® NHL2. Other binders and mix ratios are available upon request.
Well-suited for a range of backgrounds, including porous mineral backgrounds or projects looking for a highly textured final finish.

Promix Bonding Coat suits various rendering or plastering applications including bonding and harl coats. Promix Bonding Coat should be used as part of a multi-coat render application, preferably in conjunction with at least one coat of Promix Coarse Basecoat on top of Promix Bonding Coat. 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 2.8m² at a 5mm 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.
