Surface Preparation
Proper surface preparation is fundamental for the long-term performance of this product. The exact requirements for surface preparation vary with the severity of the application, expected service life, and initial substrate conditions. All sharp edges and welds should be ground to a 3 mm (120 mil) radius with an abrasive disc. Optimal preparation will provide a thoroughly clean surface free of all contaminants and roughened to an angular profile between 75-125 m (3-5 mil). This is typically achieved through initial cleaning and degreasing, followed by abrasive blasting to achieve a near-white metal cleanliness or mechanical preparation.

Mixing
Mix the activator thoroughly into the base using the mixing rod, scraping the sides and bottom of the container. Mix by weight, 2 parts Base to 1 part Activator. Mix thoroughly to produce a uniform material without streaks. Never add solvents.

Application
Use a heavy-duty plastic broom or putty knife to apply a minimum thickness of 6mm. Work the material into the substrate profile to achieve maximum adhesion and eliminate any trapped air. Contour to correct shape with a putty knife or plastic applicator. If a mold or form is used, make sure to coat its surface with a release agent to prevent material adhesion.

Application Temperature:
Keep between 55 to 95ºF (17 to 35ºC). Substrate: keep between 45 to 105ºF (7 to 40ºC). the difference in temperature of the substrate and the material should never exceed 10ºF, 5ºC. Substrate shall be a minimum of 5ºF (3ºC) 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 (75ºF+) for ease of mixing.
