The requirements for coating thickness for anti-corrosion vary depending on the corrosive environment in which the steel structure is located (the following atmospheric environment classification is classified according to ISO 9223-2012):
For atmospheric environments of C1 and C2 levels, it is recommended that the coating thickness be greater than 0.1mm;
For C3 level atmospheric environments, it is recommended that the coating thickness be greater than 0.15mm;
For C4 and C5 atmospheric environments, it is recommended that the coating thickness be greater than 0.2mm;
For CX grade atmospheric environments, it is recommended that the coating thickness be greater than 0.3mm.

The surface needs to be manually or mechanically polished with non-metallic abrasives, fibers, or hand sandpaper to form a rough surface, ensuring no smooth surface |
Use approved non-metallic abrasives for sandblasting cleaning to produce a sharp and angular rough surface |

Galvanized steel |
The surface should be clean, dry, and have a suitable roughness |
Clean the sand with non-metallic abrasives to obtain a clean, rough, and uniform surface |

The construction environment should have a temperature greater than 5 ℃, humidity less than 80%, no dust, and it is prohibited to work in rainy or snowy days.
This product can be applied and sprayed in the following way: using airless spraying.
Brush coating: Recommended for pre-coating and small area painting or repair.
Roller coating: recommended for pre-coating and small to medium area coating or repair.

The determination of drying and curing time is based on temperature and relative humidity, with relative humidity below 85%. Surface (touch) dryness: a state where there is no residue or adhesion of fingerprints when lightly pressed with fingers.
After drying, reapply with the shortest interval: the recommended shortest time interval for applying the next coating. Drying/curing to usable: The shortest time the coating can be permanently exposed to a specific environment/medium.
