- Surface Preparation
- For best results clean area to be repaired to remove loose dirt, scale and oils. Use MEK or a similar solvent and a degreaser if oils are present. If possible sand or grind the area with course paper or disk.
- Mixing
Thoroughly mix Activator into Base with mixing stick scraping sides and bottom of container or mixing board. Mix by volume 1 parts Base to 1 part Activator. Or by weight 100 grams Base to 119 grams Activator. Mix thoroughly to produce an even colored, streak-free material.
- Thinning
If desired, thin with Kelone blend from 5% to 7.5% by volume
- 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 diamond tipped tools only. Sanding/Grinding is possible if done within 1 hour of application at 77ºF, 25ºC. Caution: Material cures rapidly. Use only the quantity of material which can be easily applied within 4 to 5 minutes. Spreading mixed material on a mixing board or other flat surface will extend the working life. Large holes and cracks can be bridged with glass or metal cloth.
- 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 30-45 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. Caution: Material cures rapidly. Use only the quantity of material which can be easily applied within 4 to 5 minutes. Heating will accelerate cure time.
- Overcoat / Cure Time
- Re-coat as soon as possible while material is still soft, within 1 hour at 77ºF, 25ºC. If overcoat window is exceeded abrade surface with course sandpaper, grinder or brush blast. Full cure before immersion 45 minutes at 77ºF. Add 10 minutes additional cure time for each 10ºF below 77ºF. Subtract 15 minutes of cure time for each 10ºF above 77ºF.
- Clean Up
Clean tools immediately after use with M.E.K., Acetone, 98+% Isopropyl Alcohol or similar
