Construction Method

Material Pre-treatment

The coated metal surface must be thoroughly cleaned of oil, scale, rust, and old coatings. Shot blasting or sandblasting methods can be used to achieve the Swedish rust removal standard Sa2.5, with a roughness of 30-70μm. Alternatively, manual rust removal can be employed to meet the Swedish standard St3, with a roughness of 30-70μm.

2. Mixed

Priced by weight ratio (as indicated on the product packaging)

While mixing, slowly pour the hardener into the main agent while continuously stirring to ensure thorough and even mixing.

After the mixed paint has matured (at 23±2℃) for 20 minutes, filter it through a 80-100 mesh sieve and pour it into another container for later use.

Mixed paint has a shelf life of 2-3 hours, please schedule usage according to the progress of the application.

3. Construction Conditions

The coating operation should be carried out as soon as possible after the substrate treatment, generally not exceeding 6 hours. If overcoating on the primer or intermediate coat, construction should be recommended based on the paint curing time. The substrate surface temperature and ambient temperature should generally not be lower than 10°C, with the surface temperature at least 5°C higher than the dew point, and the relative air humidity should not exceed 75%.

4. Coating Methods

This paint can be applied using brush painting, airless spraying, and air-assisted spraying methods.

5. Dilute

Generally, paint requires a compatible thinner to adjust viscosity and clean tools. For spraying, a recommended ratio is 10-20%, while for roller and brush application, the ratio should be 5-8%.

6. Coating Spacing

One-component paint can be coated after drying. For two-component paint, it is recommended to wait the following time intervals before coating:
