Common Flooring Types: Natural Stone Flooring

Natural Stone Flooring

Marble

Overview and General Characteristics: A beautiful floor surface that is not suited for large commercial areas or heavily trafficked areas due to its soft nature (scratches easily), high absorbency (stains easily) and acid sensitivity.

Composition: Combination of calcite and calcium carbonate.

Maintenance Characteristics: Penetrating sealers perform best on marble. Acrylic-based finishes can be used but success is often spotty. Marble should only be cleaned with neutral cleaner – avoid acid-based products, high alkaline products and products with high chelation.

Slate

Overview and General Characteristics: Slate is a smooth, soft, natural stone available in a wide variety of textures, colors and sizes. It offers good durability and stain resistance due to its semi-porous nature.

Composition: Shale, clay quartz.

Maintenance Characteristics: Slate is generally not finished with acrylic-based products although, if used, they will usually adhere. Penetrating sealers can be used if desired and are often recommended for areas exposed to food and liquid spills. Clean with neutral detergent.

Granite

Overview and General Characteristics: Granite is used sparingly in commercial buildings due to its high cost. It is hard, doesn’t easily scratch and is stain-resistant – making it ideally suited for residential flooring.

Composition: Quartz and feldspar mixture.

Maintenance Characteristics: Granite’s hard, smooth nature make it unsuitable for finishing with acrylic-based products. Clean with neutral detergent.
