Spray Coating of Topcoat

I Site Cleanup
1. Clean and neatly place the unnecessary or completed objects and tools;
2. Orderly deliver the needed work pieces to the workplace;

II Preparation Work
1. Check whether the air compressor and oil water separator is run properly or not. The water in oil water separator should be discharged once to twice in sunny day, and four to six times in rainy days (depending on the weather and humidity);
2. Check if the tool (spray gun) is normal, the caliber of the spray gun should be 1.5-1.8
3. Place the modified colored paint still for 10-15 minutes and filtrate with a 200-mesh filter cloth;

III Check
