Lime Plaster (Medium)
Lime Plaster (Medium) is a natural plaster product that combines the timeless beauty of old-world lime plaster and 21st century technology to outperform any traditional product on the market today.
Formulated from hydrated lime, fine-grain sand and proprietary natural additives, it contains a slightly larger aggregate than the “Fine” version of Lime Plaster to create a striking Marmorino-style finish at a fraction of the cost of comparable European plasters. (For a Venetian-style finish, see Lime Plaster (Fine).

Lime Plaster (Medium) stands apart from synthetic plasters and cement-based coatings due to its natural breathability. Unlike dense, impermeable finishes that trap moisture behind the wall surface, * allows water vapour to pass through, reducing the risk of mold, mildew, and structural deterioration. This permeability is a key reason why lime finishes have remained a trusted solution for centuries, particularly in climates that experience significant temperature and humidity fluctuations. By allowing buildings to “breathe,” * helps maintain a stable interior environment while preserving the integrity of the wall assembly.
Another advantage of *(Medium) is its remarkable longevity. As lime cures, it undergoes a process called carbonation, during which it absorbs carbon dioxide from the air and gradually returns to a limestone-like state. This natural hardening process not only improves durability over time but also contributes to environmental sustainability by reabsorbing CO₂ during its lifespan. When compared to products that rely heavily on synthetic additives or chemical binders, this makes lime plaster an eco-conscious choice for both new construction and restoration work.
Design flexibility is another significant benefit. *(Medium) can be tinted to achieve a broad spectrum of colours without relying on artificial pigments that fade prematurely. Whether a project calls for a subtle, traditional finish or a bold contemporary statement, * can be applied in layered textures, polished to a Venetian sheen, or left matte for a rustic, heritage-inspired aesthetic. These finish options make it a preferred material among architects, designers, and artisans looking for both beauty and performance.
In modern building applications, * also serves as an excellent complement to energy-efficient wall systems, including stone, wood-fibre substrates, and Exterior Insulated Finish Systems (EIFS). Its compatibility with natural building materials makes it especially attractive for homeowners prioritizing sustainability and indoor air quality. When paired with proper substrate preparation and skilled application, * (Medium) delivers a finish that resists cracking, naturally inhibits microbial growth, and ages gracefully rather than degrading.
Whether used to restore historical architecture or to elevate modern interiors, * (Medium) offers unmatched character and lasting value. Its unique balance of craftsmanship, performance, and environmental benefits makes it more than just a surface treatment—it becomes part of the architecture itself, enhancing both the aesthetic experience and the long-term durability of the structure.
