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 to prevent oxidation of surface. Prime as needed..
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 as needed.
- 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 1-part Base to 1-part Activator. Or by weight 100 grams Base to 100 grams Activator. Mix thoroughly to produce an even colored and streak-free material.
- 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 plastic applicator or putty knife. 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. Machining & Grinding is best done within 8 hours of application at 77ºF, 25ºC (add 1-1/2 hour for each 10ºF below 77º, subtract 1 hour for each 10º above 77ºF). Machining & Grinding can be done after this time, but the material does become very hard and will rapidly wear bits and disks. Large holes and cracks can be bridged with glass or metal cloth. Condensers, Heat exchangers, Divider plates, Manways, Pumps, Impellers, Propellers, Valves, Hydro-Wheels, Pipe Elbows.
- 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. If necessary Base component of material can be heated by microwave for 30 seconds for a 1 KG Base unit or by warm water bath. Heat activator by warm water bath only. If necessary let material cool before application. Application onto surfaces above 77F (25C) may cause the material to sag/slump. This will increase as temperatures increase, so single coat thickness must be reduced.
- Overcoat / Cure Time
- Recoat while material is still soft (fingernail indent), between 2 to 8 hours at 77ºF, 25ºC. If overcoat window is exceeded abrade surface with course sandpaper, grinder or brush blast. Full cure before immersion 72 hours at 77ºF (25C). Add 1 day additional cure time for every 10ºF below 77ºF. Subtract 15 hours of cure time for each 10ºF above 77ºF. Force cure with heat for best performance for 1 hour at 200ºF (93ºC), 12 hours at 120ºF (49ºC).
- Clean Up
Clean tools immediately after use with M.E.K., Acetone or similar. ARCLEAN or 98+% Isopropyl Alcohol can be used in solvent restricted areas.
