Cornish Lime CLM28F Fibered Coarse Putty Mortar & Basecoat Render is a wet ready mixed multipurpose non-hydraulic lime putty mortar for general building work or as a coarse basecoat render with fibres for reinforcement. Available in the colour buff.
Manufactured by Cornish Lime utilising non-hydraulic mature lime putty, natural sands and fibres to create a high-performance multipurpose mortar and render. The addition of fibres assists with mitigating cracking and shrinkage while improving the load spread of the render. 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 rendering applications looking for a coarse fibered basecoat for additonal reinforcement and to minimise the likelihood of shrinkage cracking.
As with any natural product, variations in colour, texture and shape may occur. In addition, images may vary slightly from actual products due to these natural variations and screen resolution. For the best consistency, ensure to acquire a sufficient amount of material with your order to avoid batch-to-batch variation.
Suitable for internal or external use, where the binder strength is appropriate for the host background or surface.
Cornish Lime CLM28F Fibered Coarse Putty Mortar & Basecoat Render is a suitable for general building and rendering applications, including coarse render coats, dubbing out, scat coats, scratch coats and float coats. Suitable for stonework, brickwork applications with different joint sizes where the appearance of fibres is not an aesthetic concern. For a coarse pointing mortar without fibres, explore Cornish Lime CLM28F Coarse Putty Mortar & Basecoat Render.
A 20kg tub yields approximately 10 litres of wet lime mortar or render. For rendering, this covers roughly 1m² at a 12.5mm thickness. For brickwork pointing, this will fill roughly 1.2m², for stonework pointing 1m² at 25mm depth or bedding 0.5m².
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 mortar, Coarse Fibered Lime Mortar and Render hardens through carbonation, a chemical process in which the plaster absorbs atmospheric COâ‚‚. Seasonal climatic variations significantly influence carbonation; external work with this product is inadvisable between September and early April.
