More about Superfine Putty Finishing Plaster
Cornerstone Superfine Putty Finishing Plaster is a wet ready mixed finishing plaster designed for internal finishing plaster coats within an appropriate render system. Available in the colour off-white.
Engineered with precision utilising non-hydraulic mature lime putty, natural sands and chalk dust to create a high-performance superfine plaster. Made with our own premium lime putty, matured in our pits on-site for a minimum of 4 months. As a fatty lime with a high free lime content, our non-hydraulic lime putty range is more breathable, porous and flexible than our Natural Hydraulic Lime ranges.
Well-suited for a smooth and satisfying internal finish or projects looking to achieve a traditional aesthetic.
- The finest and smoothest lime putty plaster in the range
- Made with our own four months matured lime putty
- Features a finer finish than most site mixed plaster
- No pigments to prevent colour fading
- More porous than a Natural Hydraulic Lime plaster
- High vapour permeability for improved moisture management
- Straightforward to use and knock up
- A fatty and workable plaster for those behind the trowel
Suitable for internal use only, where the binder strength is appropriate for the host background or surface.
Superfine Putty Finishing Plaster is suitable for finishing coats over an appropriately prepared undercoat. Depending on the project’s aesthetic requirements, various finishing techniques, such as a float, sponge, or matte glass-like finish, can be achieved. Appropriate for various project types, including conservation, renovation, or sustainable construction.
A 20kg tub yields approximately 13 litres of wet lime plaster and covers roughly 3m² at a 3mm thickness. This product is unsuitable for thicker applications beyond 3mm.
Consumption rates will change based on the condition of the background and suction. On-site trials are advised for the best yield indication for your specific project.
As natural products, our natural 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 20kg buckets and palletised for ease of transport, storage, and handling. FIBC tonne bags are also available.
As a traditional non-hydraulic lime putty plaster, Cornerstone Superfine Finishing Plaster hardens through carbonation, a chemical process in which the plaster absorbs atmospheric CO₂. Seasonal climatic variations significantly influence carbonation; work with this product is inadvisable between September and early April if the structure is unheated.
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.
