Technistone Noble Portland Grey

Technistone Noble Portland Grey is an engineered quartz surface: crushed natural quartz bound with polymer resin and pigments. It is a manufactured material, not a natural stone. Technistone says its slabs are more than 90 percent natural minerals bound with polyester resin and pigment, with glass and mirror fractions in some collections, and it calls the material engineered stone.

Our listing shows Technistone Noble Portland Grey in a polished or matt finish and 20 mm thickness. Your quotation states the finish and thickness we have priced.

For everyday cleaning use a soft cloth with warm water and a little mild washing-up liquid, and wipe up spills promptly. Use a chopping board rather than cutting on the surface, a trivet or heat mat under hot pans, and avoid bleach, abrasive pads and harsh cleaners. Technistone's UK guide recommends an impregnating product for honed and textured finishes.

Technistone's own pages state different warranty lengths (25 years on its warranty page, 10 years on a 2023 guarantee page). Both require registration within 30 days of installation and installation by a licensed fabricator, and exclude outdoor use and commercial buildings, so we do not state a length until Technistone UK confirms it. Stoneone's 2-year workmanship guarantee is separate, and we confirm the warranty that applies to your order in writing.
