Suitable for internal or external use, where the binder strength is appropriate for the host background or surface.

Coarse Putty Mortar & Basecoat Render is a suitable for general building and pointing work as well as rendering applications, including coarse render coats, dubbing out, scat coats, scratch coats and float coats. For areas which could use additional reinforcement or shrinkage control, we recommend our Fibered Coarse Lime Putty Mortar.

Well-suited for stonework or brickwork applications with various joint sizes 8mm or above looking for a traditional finish.

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.

Consumption rates will change based on the condition of the background and suction. The width and depth of the joint will influence this estimation. 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.

Cornerstone Coarse Putty Mortar & Basecoat Render is a wet ready mixed multipurpose non-hydraulic lime putty mortar for pointing and general building work or as a coarse basecoat. Available in the colour buff.

Engineered with precision utilising non-hydraulic mature lime putty, natural sands to create a high-performance multipurpose mortar and render with a coarse traditional finish. 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 stonework applications looking for a traditional coarse buff finish or rendering applications looking for a highly breathable basecoat.

Features and benefits:

• One of our most popular and versatile mortars
• Multipurpose use for building, pointing or rendering
• Made with our own four months matured lime putty
• No pigments to prevent colour fading
• High vapour permeability for improved moisture management
• Straightforward to use and knock up
• A fatty and workable mortar for those behind the trowel
