Cornerstone Promix Superfine is a dry ready mixed plaster designed for internal finishing plaster coats within an appropriate render system. Available in the colour white, which provides a nearly pure white finish when trowelled or an off-white finish when sponged.
Manufactured by Cornerstone utilising 100% pure natural hydraulic lime, natural sands, and conservation-appropriate additives to create a smooth and satisfying superfine finishing plaster. Working aids allow for a longer open time, making this breathable plaster undemanding to apply, level, and finish.
Well-suited for a smooth and satisfying internal finish or projects looking to achieve a traditional aesthetic of a lime putty plaster but without the slower setting time.
As part of the Cornerstone Promix range for general rendering and plastering, this range is designed to provide a seamless selection from tackling challenging backgrounds to finding the ideal topcoat, ensuring high performance is paired with an ideal finish for any project.
Suitable for internal use, where the binder strength is appropriate for the host background or surface.
Relevant for applications including internal superfine finishing coats, within an appropriate render system. Appropriate for various project types, including conservation, renovation, or sustainable construction.

A 20kg bag yields approximately 15 litres of lime plaster and covers roughly 5.6m² at a 2.5mm 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.
With a diverse range of lime-based products, Cornerstone defies the standard one-size-fits-all approach, providing refined solutions to tackle each project effectively. Their products can be found on prestigious buildings worldwide, blending innovation with tradition to meet evolving industry needs.
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.
