Product Description

Silestone Gris Expo is a grey to dark-grey toned quartz stone made out of 93-05% pure quartz and a mix of resins and raw materials that are suited for interior applications.

Silestone Gris Expo has become a best seller since the day of its launch (rebranded as Silestone Grey Expo in the USA) due to the fact that is a highly versatile surface that suit both modern and traditional designs, providing a simple surface that is easy to mix and match with other materials and colour shades in any space in which it is displayed.

Gris Expo quartz has subtle dark flecks on a consistent grey based and is highly adaptable to both the most demanding environments in which a hard wearing surface is required.

Available in slabs with thicknesses in 12mm, 20mm and 30mm; this is a quartz colour that can be used for a plethora of applications such as kitchen worktops, bar counters, wall cladding, fire surrounds and floorings.

Gris Expo belongs to the Mythology Series from Silestone’s Group 1, representing great value as an investment.
Gris Expo quartz not only has anti-bacterial properties but is a non-porous surface, highly resistant to scratches, stains which requires minimal maintenance.

It will also provide the peace of mind at the time of weighing an investment by having a 25 years manufacturer’s warranty available from Cosentino, worldwide leader in ultra-compact surfaces.
