Midnight Slate

Midnight Slate Techslate Stone-Look Flooring

The depth and drama of dark slate, delivered as a warm, quiet, fully waterproof click-together plank. Midnight Slate gives you the deep, moody character of natural slate without the cold, hard feel of real stone. The surface is created with direct, lightfast digital printing rated above 7 on the ISO 105 scale, so the color stays true even in sun-drenched rooms, and a micro-beveled edge gives each plank the crisp definition of individual stone tiles. Under that surface sits a serious build: a 19/64 in (7.5 mm) plank with a mineral carrier plate core made predominantly of cement fiberboard, a highly viscoelastic intermediate layer, a ceramic-reinforced KORUS wear coating on top, and a GREEN Sound impact underlay already attached underneath. The result is completely waterproof, with 0% thickness swelling after 24 hours of water exposure. Underfoot, it behaves nothing like ceramic. The viscoelastic layer and attached underlay cut impact sound by approximately 19 dB and improve in-room sound by 35%, so it feels warmer and quieter than tile while still shrugging off chair casters, furniture drag, and heavy traffic. Rated Class 33 for commercial use and Class 23 for residential, it is built for the busiest spaces, including source-listed airports, cafes, hospitals, hotels, museums, offices, restaurants, saunas, schools, and retail shops. The Uniclic click-lock profile floats over the subfloor, and its exceptional dimensional stability (under 0.03%) allows installations up to roughly 10,700 sq ft (1,000 m²) without expansion or separation joints.

• Published acoustic data: approximately 19 dB impact-sound improvement, EN ISO 717-2, and 35% room-sound improvement, IHD-W-31, with GREEN Sound underlay. Review the test and installation requirements.
• KORUS ceramic-reinforced surface: micro-scratch resistance MSR-A1/MSR-B1, stain resistance grade 5/5, R10 slip resistance, and very good chemical durability.
• Lightfastness above 7 on the 1 to 8 ISO 105 scale: the printed slate visual holds its color in bright, sunny rooms.
• Dimensional stability under 0.03% allows joint-free installations up to roughly 10,700 sq ft (1,000 m²), and the click connection tests above 500 kg per running meter.

Important product note

This floor is finished with KORUS Protection, a ceramic-reinforced surface coating that makes Techslate tougher, more water resistant, and easier to clean while preserving its comfort, warmth, and quiet performance. Techslate is also an eco-conscious alternative to ceramic or wood floors: it is engineered to be dismantled easily and is fully recyclable through a second-life process.
