The Jura Grey is a reference limestone from Germany, with a large availability and a considerable demand. This grey limestone is mostly known for its hardness and grey colour consistency. Though, it can accept about any type of finishing, there are only a few Jura Grey finishings that are highly produced and demanded worldwide.
With an extraordinary reputation, the Jura Grey is probably the most popular and well-known natural stone from Germany. Despite having a demand focused on Europe, this limestone is also exported to several other parts of the world. There’s currently a huge availability for this natural stone, along with large reserves for future extraction. This limestone presents a thin to medium grain, with a non-uniform background and a substantial hardness. Additionally, the Jura Grey is mostly characterized by the presence of strong signs of fossils, with a darker colour sparsely distributed throughout the surface. There are mainly four types of Jura Grey finishings, in which all of them look slightly different, especially regarding the intensity of the colour.
Honed
Among all the Jura Grey finishings, the honed technique is probably the most popular one. This happens because the honed type highlights the natural elements of the stone. Therefore, inclusions and fossils become more visible, while the grey colour becomes more intense and consistent, with some silver tonalities. On the other hand, the background is quite irregular and the surface is matte, with very little reflection. In terms of applications, exterior cladding and interior applications, like flooring or coverings, are the most frequent choices.
Main Features: Non-uniform background; matte surface; natural elements; persistent grey-silver colour.
Top Applications: Interior flooring and exterior cladding.
Polished
Used mainly on interior projects, the polished finishing creates a very shiny surface, with a lot of brightness and reflection. It also highlights the natural elements of the limestone, such as fossils and inclusions. The colour also suffers some alterations, as it becomes rather clean and enhanced, with some silver shades. The background reveals to be irregular but with a very rich composition. The most popular usages for the polished finishing is certainly interior applications, where flooring is the most common one.
Main Features: Non-uniform background; shiny surface; natural elements; clean grey-silver colour.
Top Applications: Interior flooring and interior applications in general.
Sandblasted & Brushed
This finishing combination delivers a wide range of features that are highly appreciated for different types of applications, such as a strong anti-slippery capacity, a rough matte surface and a corrugated appearance. Between all the Jura Grey finishings, the sandblasted and brushed is certainly the most utilized on exterior flooring and exterior cladding. While the sandblast makes the stone whiter and more uniform, the brushed method brings back most of the natural elements of the stone, allowing it to maintain some authenticity and discreetness.
Main Features: Uniform background; matte surface; non-slip properties; natural elements; light grey colour.
Top Application: Exterior flooring and exterior cladding.
Sandblasted
The sandblasted finishing creates a quite uniform background with a concrete looking effect, due to the sand blasting silica procedure. The result is a matte surface, with a great anti-slippery capacity and a fairly rough texture. Most of the natural characteristics and elements disappear, while the grey colour loses both, intensity and variety. Additionally, the sandblasted Jura Grey presents a quite plain and discreet look and as so, it is mostly used on exterior applications, specially on cladding and coverings.
Main Features: Very uniform background; matte surface; non-slip properties; light grey colour.
Top Application: Exterior cladding.
