•	Surface Preparation - Prior to being incorporated into an assembled product, steel plated 3/4 inches or more in thickness may require blast cleaning to remove rolled-in mill scale, impurities and non-metallic foreign materials. After assembly, all weld flux shall be mechanically removed. The iron or steel product is degreased by immersion in an agitated 4.5%-6% concentrated caustic solution elevated to a temperature ranging from 150F-180F. It is then pickled by immersion in a heated sulfuric acid solution of 13% concentration, controlling the temperature at 150F. It is next rinsed clean from any residual effects of the caustic or acid solutions by immersion in a circulating fresh water bath. Final preparation is done by immersion in a concentrated zinc ammonium chloride flux solution heated to 130F. The solutions acidity content is maintained between 4.5-5.0 pH. The assembly is air dried to remove any moisture remaining in the flux coat and/or trapped within the product.
•	Zinc Coating - The product is hot-dip galvanized to the requirement of either ASTM A123 (fabricated products) or ASTM A 153 (hardware items) by immersion in a molten bath of prime western grade zinc maintained between 810 F-850 F. Maximum aluminum content of the bath is controlled to 0.01%. Flux ash is skimmed from the bath surface prior to immersion and extraction of the product to assure a debris free zinc coating.
•	Top Coat - All galvanized exterior surfaces visually exposed are coated with a Urethane or Triglycdyl Isocyanurate (TGIC) Polyester Powder to a minimum dry film thickness (DFT) of 2.0 mils. Prior to application, the surfaces to be powder-coated are mechanically etched by brush blasting (Ref. SSPC-SP7) and the zinc coated substrate preheated to 450 F for a minimum of one (1) hour in a gas-fired convection oven. The coating is electro-statically applied and cured by elevating the zinc-coated substrate temperature to a minimum of 4000 F in a gas-fired convection oven.

Pre-heat kettle to approximately 250°F and begin adding bags of material in 5-10 bag increments until full. When adding material to the kettle, add one packet of color per bag of material. Heat material to approximately 400°F. Be sure to maintain constant agitation and avoid overheating the material.

26.3.4.2. If necessary, heat the smoothing irons in a propane flame until red-hot.

26.3.5. Placement through One of the Following Two Methods:

Method 1.

26.3.5.1. Mixture proportions are proprietary but must account for color and traffic use.

26.3.5.2. Thoroughly mix part 'A' (Resin) with part 'B' (Hardener) utilizing a suitable heavy duty electric paddle mixer or similar in amounts recommended by manufacturer.

26.3.5.3. Pre-wash and completely dry all aggregates and provide bagged materials consistent with the mixture proportions before batching and mixing.

26.3.5.4. Thoroughly mix aggregates and polyurethane binder mixture in the amounts recommended by manufacturer.

26.3.5.5. Apply, uniformly spread and finish surface between the grade control forms utilizing rubber squeegees and trowels as recommended by the manufacturer and as shown on the plans.

26.3.5.6. Imprint using an approved mold capable of providing a 9mm to 13mm (3/8 inch to 1/2 inch) deep imprint with the design details shown on the plans.

26.3.5.7. Use a manufacturer approved release agent to prevent imprinted material from sticking to the mold.

26.3.5.8. Provide a final texture and pattern shown on the plans.

26.3.5.9. Border the decorative crosswalk by installing two white parallel lines (minimum 6 inches wide) with a PennDOT approved pavement marking material that extends from face of curb to face of curb or edge of shoulder.

26.3.5.11. Do not allow vehicular traffic or loads on the system for a minimum of two hours from applications or until the mixture is tack free.

Method 2.

26.3.5.12. Discharge the material into buckets treated with a suitable release agent and apply it in the desired area. Using the hot smoothing irons, spread the material to the desired thickness and tool it to a smooth bubble-free surface. If required, battens can be applied to the surrounding wearing course to aid in the determination of thickness. Once the desired surface texture has been achieved, apply a thin layer of dry silica sand to the surface.

26.3.5.13. If joining new material to some already in place, be sure to heat the existing material to a temperature of approximately 300°F with a propane torch before ironing the new material into place to ensure a tight bond and prevent joint shrinkage.

26.3.5.14. Once the sand has been applied, begin imprinting the material with the appropriate mold. Press the mold into the material to a depth of 0.2" - 0.5" unless otherwise requested. Imprint in such a manner that the pattern is straight from beginning to end. Avoid excessive material displacement while imprinting. Periodically inspect the mold and remove any adhered material. Complete the pattern along the edge lines using detail tools. These tools may be heated if necessary.

26.3.5.15. If the pattern needs to be corrected, it can sometimes be reheated and smoothed with the irons before being reprinted. In extreme cases, the material will have to be removed and reapplied.

26.3.6. Submittals/Qualifications.

26.3.6.1. The installer will provide technical specifications, MSDS sheets and color and pattern samples as needed. Typical color samples will be mounted and delivered to the Project Owner.
