SURFACE PREPARATION: Steel surfaces are to be abrasive blasted with chloride free abrasive. Exterior applications to SSPC SP-10 Near White metal finish. Immersion applications to SSPC SP-5 White metal 3 to 5 mil profile. Grind flat all burrs, weld seams, radius sharp edges. Fresh blasted ferrous surfaces to be primed immediately with ARCOR™ S-30 Prime or ARCOR™ EE- 101 to prevent oxidation of surface. Concrete surfaces should be degreased if oil and grease contamination is present.
Degreased surface shall be high pressure washed, acid etched and high pressure washed again so surface is clean and free of all grease, oils and surface laitance. Existing coatings should be abrasive blasted to clean concrete. Prime with ARCOR™ EE-101, EE-111.

MIXING: Thoroughly mix Activator into Base with mixing stick or drill with low speed mixing blade scraping sides and bottom of container or mixing board. Mix by Volume 2 parts Base to 1 part Activator. Mix thoroughly to produce an even colored, streak-free material.
THINNING: Never thin.
APPLICATION: Use heavy plastic squeegee or putty knife. Work material into profile of substrate to achieve maximum adhesion and to remove any entrapped air. Contour to correct form with putty knife or plastic applicator. If mold or form is used, coat its surface with a release agent to prevent adhesion of the material. Machining is possible using carbide tipped tools.
Grinding is possible if done within 14 hours of application at 77ºF, 25ºC (add 1-1/2 hour for each 10ºF below 77º, subtract 1 hour for each 10º above 77ºF). Large holes and cracks can be bridged with glass or metal cloth.
APPLICATION TEMPERATURE: Material: 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. If necessary Base component of material can be heated by microwave for 30-45 seconds for a 1 KG Base unit or by warm water bath. Heat activated by warm water bath only. If necessary let material cool before application.
OVERCOAT / CURE TIME: Re-coat while material is still soft, between 1 to 2 hours at 77ºF, 25ºC. If overcoat window is exceeded abrade surface with course sandpaper, grinder or brush blast. Full cure before immersion 36 hours at 77ºF. Force cure with heat for best performance for 8 hours at 120ºF (49ºC); 2 hours at 250ºF (121ºC)
CLEAN UP: Clean tools immediately after use with M.E.K. or similar
WARNING: Base contains epoxy resin. Activator contains alkaline amines, a strong sensitizer. May cause skin irritation, sensitization or other allergic responses. Use with good ventilation, particularly if heated or sprayed. Prevent all contact with skin or eyes. Wear protective clothing, goggles, gloves or barrier creams. Keep containers closed when not in use. Wash thoroughly after handling. In case of skin contact immediately wash with soap and water. In case of eye contact, flush with water for 15 minutes. If irritation persists seek medical attention.
