Superfine Putty Finishing Plaster
Verified by manufacturer 28 days ago
A ready mixed non-hydraulic lime putty plaster with a superfine texture suitable as an internal fine finishing coat with a refined natural white coloured finish.
Application
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.
Description
