DEX-O-TEX SPECTRUM TERRAZZO FLOORING

1.) PRODUCT DESCRIPTION
A) Composition
Dex-O-Tex Spectrum Terrazzo is a troweled, thin-section, jointless floor.  It is a water-phase polyacrylate resin composition incorporating marble chip aggregates.  It can also form an integral, sanitary coved base.

Dex-O-Tex Spectrum Terrazzo is customarily applied in either of two thicknesses - 3/8” (9mm) or 1/2” (12mm).

Because Dex-O-Tex Spectrum Terrazzo “breathes”, it is not loosened from substrate by moisture vapor transmission.

Crossfield Products Corp., producers of Dex-O-Tex Spectrum Terrazzo, is a Manufacturing Member of the National Terrazzo and Mosaic Association (NTMA), the terrazzo industry trade organization.  Dex-O-Tex Spectrum Terrazzo meets all physical requirements of NTMA recommended product specifications for polyacrylate terrazzo.

Dex-O-Tex Spectrum Terrazzo is available in many matrix colors (including white) and a complete range of marble chips.

B) Typical Uses

Floors for entrance and elevator lobbies, corridors, certain kitchen service, toilet spaces. etc.
