Dex-O-Tex Terracolor Flooring

1.) PRODUCT DESCRIPTION

A) Composition
Dex-O-Tex Terracolor is a thin-section, trowel applied decorative flooring designed to produce a jointless floor and base. Terracolor is installed at 1/4" (6,33 mm) thickness. Terracolor consists of decorative aggregates embedded in a colored epoxy matrix. it is finished with clear epoxy resins which offer superior scratch resistance and withstand heavy abuse and impact.

Dex-O-Tex Terracolor may be applied over concrete, metal, or wood substrates (consult Crossfield Products Corp. for detailed specifications). Terracolor is available in the Dexcide series incorporating an antimicrobial biocide which protects against growth of bacteria, fungi, algae, and actinomycetes. Terracolor is often used in conjunction with Dex-O-Tex Wall-Glas to produce an integrated and seamless floor and wall system.

B) Typical Uses

B. Single-Source Responsibility: Obtain epoxy mosaic composition flooring materials, including primers, resins, hardening agents, colored aggregates and finish or sealing coats, from a single manufacturer.

C. Qualified Materials: Request for material approvals for any products other than the specified products must be submitted to the architect two weeks prior to the bid, including complete application specification, physical characteristics, and chemical resistance data. Any request after this date will not be accepted. Failure of performance requires immediate removal and replacement of unapproved substituted material with those originally specified at no cost to the owner, architect, construction manager, or general contractor.

1.06 DELIVERY, STORAGE AND HANDLING
A. Deliver materials in original packages and containers with seals unbroken and bearing manufacturer's labels containing brand name and directions for storage and mixing with other components.
