Product Information

Slate often splits along its own natural planes of weakness. That's why the surface is often uneven. However our Brazilian tiles are selected from a certain range just to make sure that uneven surface (riven surface) is kept at minimum.

These black slate tiles are both rich in texture and depth and will make a great impact wherever you choose to put them. Brazilian Riven Slates are extremely flat, with minimal surface ridges.

Installation & Care

All products listed here can be purchased from our online store (Adhesive, grout, sealers or maintenance items).

General Information for Tile & Stone:

  • Substrate should be clean, dry, level and should not move. Decoupling membranes are recommended for flooring applications if shift in substrate is expected.
  • Dimensions listed here are nominal as slight variations in size and thickness may occur with most stone & porcelain tiles.
  • Minor edge chipping may occur in handling, installation & transport. During installation process, these can be used as cuts.
  • Natural stone can vary in colour, tone, size (within tolerance). During installation, mixing the tiles naturally (blending) are recommended rather than using similar shades together.

  • Flexible adhesive is recommended, particularly substrates with movement, or when underfloor heating is at present or planned in installations.
  • All tiles must be solidly bedded.
  • Standard set adhesive sets slowly (24 hours) whereas fast set adhesive sets within 3 hours (depending on weather conditions).


  • Apply grout at least 12 hours after the tile installation.
  • Select width joint accordingly to accommodate any variation in tile sizes.
  • We recommend the use of flexible grouts.
  • When mixing multiple sizes together (i.e. patterns) the grout joint may vary in width between the varying sizes of tiles within the pattern.

Sealing & Maintenance:

  • All natural stone tiles need sealing during installation; Generally we recommend to apply one coat before grouting and one coat after grouting.
  • Depending on usage of the floor, re-seal the tiles every 6-12 months.
  • Use maintenance products that are manufactured for natural stone. Do not use acidic cleaners.

    Hi can Brazilian Black Slate Tile be used indoor and out. Wanting same tile indoor and out where bifold doors are.

    • Stone Deals

      Thank you for your query Lee, Due to the thickness of the tiles being at only 10mm, it is therefore not suitable for outdoor use. However we do the Brazilian Black Paving Tile in a Grand Opus pattern tile which is similar to this item, this can be for external use. Please order a free sample of this item as this will allow you to get a better idea of the structure of the tile. For all other queries, please do feel free to contact us and we will do our best to help

    Is the Brazilian Riven Slate relatively smooth. I have had Indian Riven Slate in the past and it seems so riven that it is positively uneven and not really suitable for a kitchen, but only for a very rustic entrance hall for example. Thanks David

      Thank you for your query, Our Brazilian Riven Slate tiles have a textured riven finish naturally created by the manufacturing process used during its resizing process, which is one of the main selling points of this very unique natural stone. I hope this has been helpful.
