Jade Schiefer

Jade Schiefer is a greenish Brazilian slate with a quiet bedding and a natural building-stone effect. At ROSSITTIS we carry it for tiles, floor solutions and skirtings wherever a robust green slate for indoors and out is called for.

About Jade Schiefer

Jade Schiefer is a material with a natural calm. The colour moves between green, grey and earthy undertones, and the typical slate structure remains clearly recognisable. This produces a surface that appears less decorative than many green marbles, but markedly more honest, more craftsmanlike and more robust. In corridors, stairwells, terraces, wall surfaces or entrance areas, precisely this mix of colour and materiality works very well. Compared with black slate, Jade Schiefer appears lighter and softer; compared with green exotics, considerably more restrained.

The stone comes from Brazil, from Minas Gerais, an important region for dense and readily workable slates. Materials of this kind are valued indoors and out because they are independent in design terms and technically bring more everyday tolerance than calcareous rocks. Jade Schiefer is particularly suited to floor solutions, steps, plinths and wall cladding wherever a natural, non-glossy surface is wanted.

Finishes

Jade Schiefer is available in a range of finishes. The finish affects appearance, feel and the care it needs.

Spaltrau kalibriert

Wie spaltrau (natürlich gespaltene, raue Mattoberfläche), zusätzlich mit kalibrierter Rückseite: Die Plattenunterseite ist plan geschliffen für gleichmäßige Stärke und vereinfachte Verlegung. Empfohlen für Außenbereiche, Pflasterflächen und Fassadenverklebungen mit Anspruch an präzise Maßhaltigkeit.

Satiniert kalibriert

Wie satiniert (gebürstete Mattoberfläche mit subtiler Tiefe), zusätzlich mit kalibrierter Rückseite: Die Plattenunterseite ist plan geschliffen für gleichmäßige Stärke und vereinfachte Verlegung. Empfohlen für Bodenflächen, Treppenstufen und Verklebungen mit Anspruch an präzise Maßhaltigkeit.

Spaltrau

Die Oberfläche entspricht einer natürlichen Spaltung des Gesteins — die schiefertypische schichtige Charakteristik tritt voll zur Geltung. Matte, raue Anmutung mit hoher Rutschsicherheit und ursprünglich naturhafter Wirkung. Empfohlen für Außenbereiche, Mauerverkleidungen und stark beanspruchte Pflasterflächen.

Care & fabrication

Jade Schiefer should be sealed above all on floors, plinths and external surfaces, so that dirt and moisture penetrate the surface less readily. This keeps the natural colour calmer and more even.

For cleaning and maintenance, pH-neutral natural stone cleaners, water and — depending on the finish — a cloth, mop or soft brush are suitable. On riven surfaces, sand, soil and organic deposits should be removed regularly.

Avoid strongly film-forming maintenance products and aggressive cleaners that can leave residues in the texture. Slate is best cleaned and maintained when the surface stays open and clean.

Outdoors, clean and maintain regularly, remove leaves and early algal growth promptly, and refresh the sealer according to use. That keeps the slip-resistant surface functional and visually clean as well.

Frequently asked questions

Is Jade Schiefer suitable for outdoor use?

Yes. Jade Schiefer is frost-resistant and is typically used for floors, stairs, wall cladding and other external applications.

Which finishes are available for Jade Schiefer?

The surface finishes currently held in stock are listed in the »Finishes« block on this page.

Where does Jade Schiefer come from?

The stone comes from Brazil, from Minas Gerais. The region is known internationally for dense and readily workable slates.

How do I clean Jade Schiefer correctly?

For cleaning and maintenance, pH-neutral natural stone cleaners, water and — depending on the finish — soft cloths or brushes are sufficient. On textured surfaces, loose dirt should be removed regularly.

Is Jade Schiefer suitable for heavily used floors?

Yes, very much so for ordinary floor applications. With a bulk density of 2,720 kg/m³ and a flexural strength of 24.3 MPa the stone is robust, even though it does not reach the hardness of a granite.

Jade Schiefer or black slate?

Jade Schiefer appears more colourful and somewhat softer, black slate more neutral and more severe. Technically both sit in a similar, robust slate class.
