Construction Conditions:

Surface treatment:

1.Steel should be sandblasted to Sa2.5 or manually derusted to St3, with surface roughness of 40-70μm, ensuring the substrate surface is clean and dry.
2.After meeting the rust removal standards, primer application should be completed within 4 hours. Surfaces not coated in time should be reprocessed.
3.Prior to applying the topcoat, ensure the primer surface is clean and dry.

Temperature and Humidity:

1.Substrate temperature should be 0 to 50°C, and at least 3°C above the dew point. Relative humidity should not exceed 85%.
