2.9 Coating.

Surface preparation.

Check the cleanliness and roughness of the steel surface before painting with the naked eye. Steel surfaces must be clean and dry, free of dust, scale, grease, oxidizing skin, rust or other contaminants. The inspectors compare the surface cleanliness of the steel surface with the coating plan in accordance with the relevant standards.

For steel that does not meet the surface preparation, the contractor shall bear the cost of refusing to paint or cleaning again.

Visual inspection must be completed within 4 hours of surface preparation.

b) Visual inspection.

After painting is completed, the painted surface is required to carry out a visual inspection of the final coating defects, detection of flow, bulging, wrinkle, cracking, foaming, shrinking holes, abrasives or foreign substances impregnated, peeling, oxidation or corrosion, pores and other phenomena. The coating must remove all foreign substances to avoid other defects such as bubbles, hanging, leakage, etc.

c) Adhesion detection.

The customer may request a pull test. The absolute minimum value of the experimental results is 5MPa.

d) Dry film thickness detection.

Measured at 5 points per 10 square meters, the average thickness cannot be lower than the specified thickness of each layer of dry film. A single measuring point must not be less than 80% of the specified film thickness, up to 2 times the specified film thickness or the coating manufacturer's coating system data sheet requirements.

e) Detection records.

ll inspection procedures must be fully documented, including the location of the inspection part, the detection device, the detection time, the inspector and the problems it finds.
