Immerson: remove all oil, grease, surface contamination, loose rust, scale and any old coating. Although designed for use in less than ideal surface preparation it is preferred that one strive to attain as close to an SSPC SP-5, in as many areas as possible, to achieve the best long term performance of the overall coating system. At a minimum an SP-6 is required. In all cases a 3-5 mil profile is required dry: Remove all oil, grease, surface contamination, loose rust, scale, and any old coating. Although designed for use in less than ideal surface preparation the best long term performance is attained with SP_6 cleanliness at 2-3 mil profile.
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. Sandblasting and /or scarification may be recommended depending on surface. Existing coatings should be abrasive blasted to clean concrete.
- Mixing
Thoroughly mix Activator into Base with mixing stick or drill with low speed mixing blade scraping sides and bottom of container. Mix by Volume 2 parts Base to 1 part Activator. Or by weight; 100 grams Base to 34 grams Activator . Mix thoroughly to produce an even colored and streak-free material.
- Application
Brush: medium to stiff bristle of sufficient quality that bristles do not pull out and stick in coating
Roller: use good quality 1/8”-1/4” nap.
Plural Spray: 2,000 psi, 0.015-0.017 tip.
Airless Spray: Low air pressure 25-40 psi, 0.015-0.017 tip.
Conventional Spray: Graco #700 or #800 spray gun with suitable needle/nozzle and air cap combinations. ARCOR™ EE-80 applies best at low air and pot pressure, 5-10 PSI.
All spray equipment should employ traps to prevent water and oil from contaminating coating and screens to prevent particulate contamination.- 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 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+, 24ºC) for ease of mixing. If necessary base component of material can be heated by microwave for 20-35 seconds for 1 KG unit or by warm water bath. Heat activator by warn water bath only. If necessary let material cool before application.
- Overcoat / Cure Time
By Brush, Roller or squeegee re-coat while material is still soft, but tack-free, between 2hrs-7 days at 77ºF (25ºC).If over coat window is exceeded wipe entire coated area with MEK or Acetone. By spray application re-coat between 1 hour – 7 days at 77ºF. Full cure before immersion refer to top coat data sheet. Add 2 days additional overcoat time for each 10ºF below 77ºF. Subtract 18 hours of overcoat time for each 10ºF above 77ºF.
- Clean Up
Clean tools immediately after use with M.E.K., Acetone, 98+% Isopropyl Alcohol or similar
