Flooring black slate tiles with natural surface, 20mm thick
Black slate has a dark blue gray shade when the surface is dry, it becomes black when wet. You can keep this dark black appearance by applying a color enhancing sealer. This type of slate is of a higher quality to the level of hardness, wear and the resistance to cracking. Floors with this slate will last decades. The natural cleavage on the surface gives it anti-skid properties.
- For interior, walls and floors we suggest 12 mm thick slates. 20mm or 40 mm can also be used if you want a higher thermal mass. Slate is an important accumulator of heat either passive or for heated floors, it slowly releases its heat for added comfort in the home. 20 mm is also recommended for public places. Outdoor 20 mm is recommended to be glued on a concrete slab or on well compacted crushed stone. 40mm can be placed directly on the compacted soil. The choice between the 20 or 40 mm for the exterior depends on the weight that will be imposed to the tiles.
- The natural slightly textured finish shows the natural look of slate cleavage.
- The slate of 12, 20 and 40 mm are calibrated and can still vary slightly in thickness, for this reason we recommend a minimum joint between the tiles to facilitate with the adjustments
