Country of origin: Brazil
Our Brazilian Black Slate offers you a smart, contemporary feel to any indoor or outdoor setting. This product is calibrated which means you have a consistent thickness so no surprises for you builders. This product is available in 10mm and 20mm thickness’.

Different uses for flagstones in the house and garden
20mm Black Brazilian Slate is suitable for both interior and exterior flooring. 10mm we would suggest using internally but can be used externally as wall cladding. Indoors, these flagstones work really well with underfloor heating, spreading and retaining the warmth throughout the stones. Outdoors, they are perfect for courtyard gardens, patios and seating areas.
Laying the flagstones
Outdoors, these flagstones can be laid on a sand and cement bed. Ensure the screed bed is level, and if needed use a sub-base. Spot bedding is not recommended as its makes the flagstones unstable and susceptible to fracturing.
Joint widths are a personal decision, but a 12mm gap is standard. We recommend Jointex Easy as a fixing mortar. It’s ready mixed, easy to use, doesn’t stain the flagstones and creates a very neat professional finish. It is permanently water permeable, resistant to high pressure cleaners and helps prevents weeds. Just empty the tub onto wet flagstones and work it into the joints, making sure they are firm and compact; then wait for it to dry (see the Jointex Easy Data Sheet for full details).
If laying a mix of sizes you can expect that grout joints will vary in size but once jointed this is less apparent.
Looking after the flagstones
Personally we don’t seal flagstones for outdoor use, because we think they improve with weathering. However you can seal them if you prefer.
Indoors we would definitely recommend sealing flagstones, to protect them from grease marks and household staining. It is essential to use a sealant specially made for natural stone, and we sell a range of high quality sealants for you to choose from. Some of the flagstones are more porous than others so the number of coats required will differ from one type of flagstone to another.
Should your flagstones become stained with oil, grease or ingrained dirt we recommend LTP Grimex. This is a special cleaner for indoor or outdoor areas, and brings the stone up a treat.

An important note about natural stone
Whilst we have done our utmost to ensure the stone and colours displayed on our website are accurate, they are to be used as a guide only. Because stone is a natural product, texture and colour will vary from piece to piece. As we work through the quarry, seams will yield slightly different coloured and shaped stones.
The way in which flagstones are laid, and the amount, colour and type of grout used will all impact the look of the finished design. Please bear this in mind when ordering stone samples and products.
