Floor finishes in commercial and institutional uses make considerable use of synthetic-fibre carpeting and vinyl composition tile. In areas of higher traffic harder surfaces may be used—for example, cut stone tiles of marble or granite, ceramic tile applied with epoxy adhesive to the substrate, or terrazzo. Terrazzo is made in two ways, traditional and thin-set. In the traditional form a four-centimetre (1.5-inch) layer of cement and sand grout is poured over the substrate; a grid of metal divider strips to control shrinkage cracks is set on the hardened surface, and grout mix of coloured cement and marble chips is poured between the strips. After hardening, the surface is machine polished to expose the marble chips and metal dividers. Thin-set terrazzo is made by placing the metal strips and pouring the binder and marble chips directly onto the subfloor, without the underbed of cement and sand. It is generally possible only when epoxy resins are used in place of cement binders. Terrazzo is available in many colours, and it forms a hard, smooth, and durable surface that is easily cleaned. Hardwood Floor Solid hardwood flooring of the past in lengths able to span joists is becoming more of a rare thing. Commodity flooring in a variety of lengths, some as short as 6 or 8 inches, is more the norm. Laminate Flooring Laminate flooring can cover other, existing floor coverings, as long as the total height of the flooring does not interfere with other functions. As a floating floor, laminate flooring is easy to remove and replace with new laminate flooring. Engineered Wood Flooring Engineered wood flooring is a hybrid that brings the best of solid hardwood with the functionality of dimensionally stable plywood. Hardwood veneer comprises the very top layer of engineered wood flooring. Sheet Vinyl Flooring Sheet vinyl flooring stretches from end to end of a room, often as one continuous sheet. Vinyl Tile Flooring Vinyl tile flooring is a floor covering that depends on an ultra-smooth underlayment so that bumps and imperfections from below do not telegraph to the top of the flooring. Wooden flooring Such types of flooring is mostly preferred in cold winter as wood is a bad conductor of heat and so warm temperature is maintained in the house. Small pieces of planks when kept together leaving no voids in between, constitute the wooden flooring. In some floorings a thin layer of veneer finish is also given to enhance the look. The veneer finish comes in matte as well as in glossy form. It is solely up to the owner of the house to select the suitable type of finish. Concrete flooring Concrete flooring is preferred in hot weather conditions as it maintains the temperature inside the house cool. Nowadays, many textures have emerged in concrete flooring and so people are opting such flooring. Laminates It is board made of fibre and is compressed to make a thin flat plate.
