Does the surface of home decoration paint need to be treated before construction?

1. After the second sand blasting, the yellow smoke and oxide scales will be removed from the weld bead surface.

2. After secondary sandblasting treatment, before painting spraying, surface defects, especially weld defects, should be re-examined and repaired.

3. Check carefully the dust and oil on the surface of the spray paint, and clean the surface of the dust and oil that still exists. Pretreatment qualified box should enter the construction site as soon as possible to start primer construction, time should not exceed 8.

4. Intermediate paint: Each weld, angle, edge and other hidden areas must be brushed before spraying in a large area. Construction equipment, drying conditions and time, re-painting interval, etc. must be checked to check paint spraying defects, test wet film thickness, adjust spraying nozzle and spraying speed to make spraying uniform and film thickness 50 mu.

5. Topcoat: Check the types, colours and diluents of paints according to the paint specifications, check the quality of paints, date of production, and record the batch number of production. Check the wet film thickness, adjust the nozzle and spraying speed to make the spraying uniform, reaching the film thickness of 50 mu. Inspect and correct the quality of paint construction, avoid appearance defects such as leakage, pinhole, bubble and hanging, and repair local paint defects in time. Check and correct the drying room temperature, flow time, drying time and other conditions.
