Marmoleum Cinch Loc Seal Square - Serene Grey 12" x 12"

Marmoleum Cinch Loc Seal Serene Grey — 12" x 12" Click Linoleum Floor Square

Serene Grey is a Marmoleum Cinch Loc Seal square, a 12" x 12" natural linoleum tile with a click edge that floats over the subfloor. It sits in Forbo's grey family, and Forbo pairs it with Seashell and Volcanic Ash in its room photography.

Best for: kitchens, family rooms and open-plan spaces that want a versatile, calm grey.

The Look

Serene Grey is, as named, a calm grey that works as a backdrop rather than a statement. Forbo groups it with Seashell and Volcanic Ash, so it blends naturally into a light-to-dark grey scheme. Linoleum shades vary slightly between production lots, so a sample is worth seeing first.

Why Choose Serene Grey

• Kitchen-ready finish: Topshield pro is applied at the factory and is not meant to be removed.
• Waterproof core: Forbo describes the core as waterproof to handle daily spills, though the floor should never be flooded.
• Low-toxin build: Forbo's brochure states the product contains no lead, formaldehyde or chlorine.
• Sound control: Forbo cites up to 21 dB of sound reduction over its foam underlay.

Installation

In a kitchen, keep the 3/8" expansion space at cabinets and toe kicks as well as walls, and hide it under trim. Concrete slabs need a moisture test: Forbo's limits are 75% internal relative humidity (ASTM F 2170) or 5 lb per 1,000 sq ft in 24 hours (ASTM F 1869). A vapor barrier is required over concrete either way.
