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 with 4-5 mil profile. Grind flat all burrs, weld seams, radius sharp edges. Fresh blasted surfaces to be primed with ARCOR® S-20 HT or EE-11 Prime depending upon substrate.
Concrete surfaces : 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® S-20 , EE-11 Prime, EE-79, EE-10 depending upon substrate and service.
- Mixing
Thoroughly mix Activator into Base with mixing stick or drill with low speed mixing blade. Mix by Volume 3 parts Base to 1 part Activator. Or by weight 3 parts Base to 1 part Activator.
- Application
Brush: medium to stiff bristle of sufficient quality that bristles do not pull out and stick in coating (epoxy glued bristles are best). Trim or tape to <1” nap.
Roller: use good quality 1/4” - 3/8” nap.
Plural Spray: 0.029-0.039 RAC tip, 2,500 - 3,500 PSI, Heat to 160ºF Base, 110ºF Activator.
Airless Spray use0.033-0.041 RAC tip, 4,500-5,500 PSI(65:1+). Heat Base to 85F and Act to 75F minimum. (Caution: Short Pot-Life)
Conventional Spray: Not Recommended
All spray equipment should employ traps to prevent water and oil from contaminating coating and 30 mesh screens prevent particulate contamination. Use Spray Gun such as Graco XTR-7.- Application Temperature
- Keep between 55 to 95ºF (13 to 35ºC). Substrate : Keep between 45 to 105ºF (7 to 40ºC). The difference in temperature of the substrate and the coating should never exceed 10ºF (5ºC). Substrate shall be a minimum of 5º (3ºC) above dew point. Do not apply if relative humidity exceeds 80%. If necessary heat 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 over night (75ºF+, 24ºC) for ease of mixing. If necessary Base component of material can be heated by microwave for 30 seconds for a 1 KG Base. If necessary let material cool before application. Full cure before immersion 72 hours at 72ºF (25ºC). Add 1 hours additional cure time for each 10ºF (-12.2ºC) below 77ºF (25ºC). Required Force Cure for 2 hours at 175ºF(121ºC) then 300ºF(149ºC) for 3 hours.
- Overcoat / Cure Time
By Brush or Roller re-coat between 3 and 12 hours at 72ºF (22ºC). When spraying a single coat is best at 15-60 mils depending on service. If doing multiple spray coats, re-coat between 2 and 12 hours. Full cure before immersion 24 Hours at 72ºF. Without de-humidification keep re-coat times as short as possible or wipe with Acetone immediately prior to re-coat especially if humidity exceeds 60%.
- Clean Up
Clean tools immediately after use with M.E.K., Acetone, 98+% Isopropyl Alcohol or similar
