It is a very clean and modern looking stone and can be used for both internal and external applications as it is also available in a thicker paving format at 20mm thick, which is widely used by sign writers and stone masons, due to its natural beauty and hardwearing properties.

Due to the perfectly flat honed surface, we do not recommend this product is used on floor applications.

Product Guidance

The shade of the final product will differ compared to the sample you may receive or the images shown on this website, all natural products have colour variation within and between different batches. You must ensure that you are happy with the colour variation of the product you have received before you start laying, as after installation exchange will no longer be possible.

Ensure that you have all the required material to completely the whole project onsite before commencing any work. Open all your crates at the same time, taking material evenly from each of them. This will ensure you have a good distribution of colours across the whole tiled area. DO NOT open one crate at a time using all the material before opening the next, this can result in uneven distribution of colours and can look unsightly.

Within Brazilian black slate you can occasionally find deposits of iron pyrite (fools gold) these present themselves as gold deposits inside and on the surface of the stone, if you are not happy with the appearance of theses slabs, do not laying them, you are welcome to return any of these slabs to your local branch to be swapped, after installation, it is no longer the responsibility of Natural Stone and Timber Ltd and replacements will no longer be possible.

Due to the perfectly flat honed surface, we do not recommend this product is used on floor applications.

Do not use acidic cleaners on natural stone as they can cause permanent, irreparable, damage to the colour and structure of the stone.

How many slate tiles per square?

How many slate tiles you get per square metre really does depend on the size of the tiles. Establish the width and length of the tiles in mm, multiply these together, this will give you the area of the tile, then divide 1 x this area and this will give you the amount per sqm. Example below:

600mm x 400mm size tiles (0.6 x 0.4 = 0.24). 1 / 0.24 = 4.166 giving you just over 4 tiles per sqm in this size

What to clean slate tiles with?

Daily cleaning is important, wipe up any spills immediately and sweep floors every day with soft broom to stop any build-up of dirt.

This is an excellent way to prevent build-up of dirt and debris and keep your natural stone tiles looking prefect.

On occasion you can apply a coat of Slate Oil to bring back the lustre of the natural slate, this will also offer some protection against staining.

Slate is a foliated, fine-grained metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash that shows no clear compositional layering, but can be easily split into thin slabs and plates.

Slate having those properties and great thermal stability makes it a top choice for a fireplace hearth and an area with underfloor heating.

Are slate tiles good for an outdoor patio?

We would always recommend using thicker slate for external usage and the standard 8 or 10mm slates use for internal applications.

Slate is the ideal material for patios as its extremely dense and hardwearing and will last for decades if installed correctly.
