Construction suggestions for ultra-thin steel structure fireproof coating:
1、 surface treatment Requirements: the coated metal surface is dry and free of oil stain, dust and other foreign matters; Clean the surface.
2. Open the barrel for mixing: after opening the barrel, completely mix the paint until there is no sediment and color difference at the bottom of the barrel, and then apply it.
3、 diluent And dilution ratio: 3-10% for special use of thinner for coating.
4. Construction notes:
① Avoid construction under strong light, and prohibit construction in rainy, snowy or foggy days.
② In order to prevent undercutting, the next coat shall be applied after the last coat is dry, and the spraying method shall be used as far as possible.
5. Recommended coating method: * * * pressure airless spraying, airless spraying, and manual brushing only when there is no condition.
6. The valid period is half a year. If the valid period is exceeded, it can still be used after re inspection.
