Vinyl composition tile (VCT), also commonly referred to as vinyl asbestos floor tile, is a finished flooring material used very widely in both residential and
commercial buildings from the early 1950s into the early 1980s. [1] [2] Modern vinyl floor tiles and sheet flooring and versions
of those products sold since the early 1980s do not
contain asbestos. Tiles are composed of colored polyvinyl chloride (PVC) chips formed into solid sheets of varying thicknesses (1/8″ is most common) by heat
and pressure. Floor tiles are cut into 9″ or 12″ squares.
In installation the floor tiles or sheet flooring are
applied to a smooth, leveled sub-floor using a specially
formulated vinyl adhesive or tile mastic that remains pliable. In commercial applications some tiles are
typically waxed and buffed using special materials and
equipment. Modern vinyl floor tile is frequently chosen for high-
traffic areas because of its low cost, durability, and
ease of maintenance. Vinyl tiles have high resilience to
abrasion and impact damage and can be repeatedly
refinished with chemical strippers and mechanical
buffing equipment. If properly installed, tiles can be easily removed and replaced when damaged. Tiles are
available in a variety of colors from several major
flooring manufacturers. Some manufacturers have
created vinyl tiles that very closely resemble wood, stone, terrazzo, and concrete and literally hundreds of varying patterns. Vinyl composition tiles that do not contain asbestos
took the place of vinyl asbestos and asphalt asbestos
floor tiles, which were widely used in all types of
buildings into the early 1980s. Use of tiles, sheet
flooring and adhesives containing asbestos were
discontinued when asbestos materials were determined to be hazardou
