Frequently asked questions

What exact colour tones should I expect with Brazilian Grey-Green Slate Tiles?

Our Brazilian Grey-Green slate offers an exceptionally elegant, understated colour palette. It features a predominantly soft grey base infused with subtle, natural olive-green undertones. Unlike lower-grade green slates that can look loud or inconsistent, this premium selection is highly uniform. It provides a calm, organic, mid-tone aesthetic that bridges the gap beautifully between traditional rustic properties and ultra-modern, minimalist designs.

Is grey-green slate as durable and hard-wearing as black slate?

Yes, absolutely. Geologically, our grey-green slate shares the exact same high-density, low-porosity characteristics as our signature black slate. It is structurally incredibly dense, meaning it is highly resistant to scratching, cracking, and chipping. This makes it completely ideal for demanding, heavy-traffic areas of the home, including busy family kitchens, utility rooms, main hallways, and commercial environments.

Will sealing change the colour of the Grey-Green Slate Tiles?

It depends on the type of stone sealer you choose to apply. If you use a standard matte, invisible impregnating sealer, the tiles will retain their natural, soft, chalky grey-green finish. If you prefer a richer look, applying a colour-enhancing sealer will deepen the colour, making the green undertones more prominent and giving the slate a darker, "wet-look" appearance. We recommend testing a sample tile first to choose your preferred finish.

Can these grey-green tiles be used in wet rooms and walk-in showers?

Yes, they are highly popular for wet rooms, bathrooms, and spa areas. Authentic Brazilian slate naturally possesses an exceptionally low water absorption rate, meaning it does not readily absorb moisture or foster mould growth. Furthermore, the natural riven surface texture provides an excellent, inherent slip-resistance underfoot when wet, combining premium luxury aesthetics with crucial safety.

I would like to thank Gil for the amount of time and the level of customization achieved on my project. Our slabs and tiles took a while to come all the way from Brazil but it was certainly worth the wait. We are absolutely delighted with the end result and could not praise enough all the assistance given to achieve our beautiful project - we will send you pictures shortly. Thanks again
