how to use

Surface treatment
1. Completely remove oil, moisture, sand, dust and foreign substances from the surface.
2. Sufficiently dry the surface to be coated.
3. After primer coating, clean up the welded areas (blackened and rusted areas) with a disc sander.
Then, touch up with this paint and continue coating.
Coating method
1. Coating can be done by either brush, roller, or airless spray coating.
2. Airless spray coating:
- Tip diameter : 0.017"~0.021"
- Injection pressure : 2500 P.S.I or higher(176㎏/㎠)
- Store the coating equipment after cleaning with an exclusive thinner immediately after use.
3. Sufficient performance after last coating is achieved after drying for 7 days at 20℃.
4. For one coat, about 40㎛ is appropriate, and if a thick coating is formed during one coat, sagging, bubbling, and popping may occur.
