A) Composition
Dex-O-Tex Posi-Tred "O" is a slip-retardant coating for use over concrete floors, stairs, ramps, etc. Posi-Tred "O" may also be used as the finish coating for Dex-O-Tex Cheminert or many other Dex-O-Tex composition floors. Posi-Tred "O" is a three-component material consisting of an epoxy resin, catalyst, and special metallic oxide slip-retardant aggregates. The three components are mixed together immediately prior to application, and the material is then troweled into place.
Dex-O-Tex Posi-Tred "O" is available in five different slip-retardant "profiles" ranging from very coarse to very fine. Very fine profile offers negligible slip resistance but good cleanability characteristics. Selection of profile to be used depends upon the degree of slip-retardance required, the cleaning characteristics desired, and the finished appearance appropriate for the area of use.
Dex-O-Tex Posi-Tred "O" is available in a range of standard colors. The material can be applied over concrete (new or existing), cerammic tiles, metal surfaces or Dex-O-Tex composition floors.
Formulated with environmental requirements in mind, Posi-Tred "O" contains no hydrocarbon solvents and thus meets all volatile organic substance regulations. Posi-Tred "O" has no significant odor during installation.
As an option, Dex-O-Tex Posi-Tred "O" is available in the Dexcide series which incorporates anti-microbial chemistry to control the growth of microorganisms (bacteria, fungi, etc.) on the floor surface.
Dex-O-Tex Posi-Tred "O" has U.S. Dept. of Agriculture acceptance for use in federally inspected meat and poultry plants.
B) Typical Uses
Slip-retardant surfaces for pedestrian use in manufacturing operations, stairs, ramps, and walkways.
C) Advantages – Limitations
Advantages
1. Can be applied over a wide range of surfaces.
2. No significant odor during installation.
3. Resists most common chemical spillage.
4. Wide range of color and profile selection.
Limitations
1. Temperature during application must be 60°F (18°C) or greater.
2. Requires functioning vapor barrier beneath on-ground concrete floor to prevent upwards water vapor transmission which may result in loosening of epoxy floors or improper curing of epoxy materials.
3. If sub-surface cracks, material may reflect cracks to some degree.

3.) INSTALLATION
A) Prepare surfaces by removal of laitance, grease, foreign matter, etc.
B) Apply primer.
C) Mix and trowel-apply first grout/filler Posi-Tred. Allow to dry.
D) Apply second coat Posi-Tred. Introduce slip-resistant aggregate by trowel or broadcasting. Stipple with roller.
Dex-O-Tex Posi-Tred is available through Crossfield Products Corp. factories listed above and representatives in all major trading areas.
Dex-O-Tex Posi-Tred is best cleaned by using power scrubbing and wet pick-up vacuum. Worn spots in Posi-Tred can be patched or recoated.
