how to use

Surface treatment
1. Completely remove oil, moisture, sand, dust, and other foreign matter from the surface to be coated.
2. Sufficiently dry the surface to be coated before coating.
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 : More than 2500 P.S.I (176㎏/㎠)
- Store the coating equipment after cleaning with an exclusive thinner immediately after use.
Preceding and follow-up coating
1. Preceding coating : Epoxy system, urethane system paint
1. Sufficient performance after last coating is achieved after drying for 7 days at 20℃.
2. For one coat, about 40㎛ is appropriate, and if a thick coating is formed during one coat, sagging, bubbling, and popping may occur.
3. Colors containing orange and red may be quickly discolored by UV rays when exposed outdoors, so urethane clear coat is recommended to delay discoloration.
4. When applying touch-up repairs, even the same product, color, lot number, dilution ratio, painting equipment, and painting method may cause dichroic phenomenon.
As much as possible, we recommend painting with the same LOT NO. product and the same painting tools and methods, and if there is no abnormality after checking the color difference, please work.
