Surface Preparation: Proper surface preparation is critical to the long-term performance of this product. The exact requirements for surface preparation vary with the severity of the application, expected service life, and the initial substrate conditions. Minimum preparation is mechanical preparation St2/St3. Optimum preparation will provide a surface thoroughly cleaned of all contaminants and roughened to an angular profile between 75-125 μm (3-5 mil). This is normally achieved by initial cleaning and degreasing and then abrasive blasting to a cleanliness of Near White Metal (Sa.21/2), followed by removal of residual abrasive blast residues from the surface to be coated.

Mixing: Thoroughly mix the activator into the base using a mixing stick, scraping the sides and bottom of the container. Mix by weight 2 parts Base to 1 part Activator. Mix thoroughly to produce a uniform, streak-free material. Never add solvents.

Application: Use a heavy-duty plastic scraper or putty knife to apply a minimum thickness of 6 mm. Work the material into the substrate profile to achieve maximum adhesion and eliminate any trapped air. Shape using a putty knife or plastic applicator. If molds or forms are used, ensure their surfaces are coated with a release agent to prevent material adhesion.

Application Temperature: Keep between 55 to 95°F (17 to 35°C). Substrate: keep between 45 to 105°F (7 to 40°C). the difference in temperature of the substrate and the material should never exceed 10°F, 5°C. Substrate shall be a minimum of 5°F (3°C) above dew point. Do not apply if relative humidity exceeds 90%. If necessary, heat the metal prior to surface preparation using electric heater or heat lamp. Never use gas, oil, or kerosene heaters as they will leave a greasy residue on metal surface. For best results keep all material in warm area overnight (75°F+) for ease of mixing.
