Dex-O-Tex Decor-Flor Flooring

1.) PRODUCT DESCRIPTION

A) Composition
Dex-O-Tex Decor-Flor is a thin-section, trowel- or "broadcast"-applied flooring designed to produce a jointless floor and integral coved base. The completed floor is approximately 1/16" - 1/8" (1,59-3,18 mm) thick and consists of colored quartz granules embedded in a clear epoxy mastic. It is resistant to hydrocarbon greases, food creases and fats, and a range of chemicals.

Dex-O-Tex Decor-Flor can be applied over concrete, metal or wood sub-surfaces. (Consult Crossfield Products Corp. for detailed specification for wood surfaces.)

Quartz aggregate granules are available in seven basic colors (brown, buff, green, grey, blue, red, white). These aggregates may be mixed to make any color combination which the above aggregates can produce.

B) Typical Uses
Floors for laboratories, toilet rooms, kitchens, food processing areas, institutional floors, swimming pool perimeters, etc.

C) Advantages – Limitations

Advantages
1. Monolithic, including integral base.
2. Resistant to many chemicals. (Contact Crossfield Products Corp. for separate chemical resistance table.)
3. Produces a rapidly-installed, decorative seamless floor at moderate cost.
4. Installed only by Qualified Dex-O-Tex Contractors – factory trained and approved.

Limitations
1. If sub-surface cracks, Dex-O-Tex Decor-Flor may reflect cracks to some degree.
2. Water vapor transmission upwards through on-ground concrete slabs may result in loosening of epoxy floors or improper curing of epoxy materials.

A. Substrate: Perform preparation and cleaning procedures according to flooring manufacturer's instructions for particular substrate conditions involved, and as specified. Provide clean, dry, and neutral substrate for flooring application.

B. Concrete Surfaces: Shot-blast, acid etch or power scarify as required to obtain optimum bond of flooring to concrete. Remove sufficient material to provide a sound surface free of laitance, glaze, efflorescence, and any bond-inhibiting curing compounds or form release agents. Remove grease, oil, and other penetrating contaminates. Repair damaged and deteriorated concrete to acceptable condition. Leave surface free of dust, dirt, laitance, and efflorescence.

C. Materials: Mix epoxy resin components when required, and prepare materials according to flooring system manufacturer's instructions.

3.03 APPLICATION

B. Broadcast Coats: Apply liberal application of clear epoxy resin mixture, allow to self-level, broadcast (by hand or spray machine) ceramic-coated quartz aggregate, allow to set to hardness, sweep off excess unbonded aggregate and repeat process to achieve total nominal thickness of 1/16" - 1/8".

C. Finish or Sealing Coats: After quartz-filled broadcast coats have cured sufficiently, apply finish coats of type recommended by flooring manufacturer to produce finish matching approved submittal sample and in number of coats and spreading rates recommended by manufacturer.
1. Finished floor shall be 1/16" - 1/8" thick, uniform in color and free of trowel marks.
