The performance of this product depends on the degree of surface preparation. Surfaces to be painted must be clean, dry and free of contaminants. Before painting, all surfaces must be assessed and prepared in accordance with ISO 8504:2000.
Accumulations of dirt and soluble salts must be removed. Accumulated dirt is generally removed with a dry bristle brush. Soluble salts should be washed off with fresh water.
Oil and grease must be removed in accordance with the SSPC-SP1 solvent cleaning standard.
Blast clean to Sa 2½ (ISO 8501-1:2007) or SSPC-SP6.
Surface defects exposed during blasting must be ground, filled or treated by a suitable method.
Interprime 198 is suitable for application over blast-cleaned surfaces that originally met the above standard, but the surface is allowed to be exposed for 7–10 days under good shop conditions. At this point the surface degrades to Sa 2, but must be free of loose powdery deposits.
Repair and on-site touch-up: this product is designed for use on surfaces prepared to St 2 (ISO 8501-1:2007) or SSPC-SP2. When using power tools, avoid polishing the surface. This product is also suitable for surfaces sweep-blasted to Sa 1 (ISO 8501-1:2007) or SSPC-SP7. On poor surfaces, brushing helps improve coating performance.
Interprime 198 is suitable for application over most aged coatings. Loose or flaking coatings shall be removed until a firm film edge is exposed. Smooth epoxy or polyurethane coatings may require abrading.
| Mixing | This product is a single-component coating; stir thoroughly with a power mixer before each use |

| Mixing ratio | N/A |
| Suitable for airless spray | Recommended: nozzle diameter 0.43–0.53 mm (17–21 thousandths of an inch); total paint pressure at the nozzle not less than 176 kg/cm² (2503 psi) |

| Brush | Recommended | Typical thickness 40–50 µm (1.6–2.0 mil). Care shall be taken to avoid under-application | |
| Roller application | Recommended | Typical thickness 40–50 µm (1.6–2.0 mil). Care shall be taken to avoid under-application | |
| Thinner | International GTA007 | Do not exceed the thinning limits of local environmental regulations |
| Cleaner | International GTA007 |
|---|---|
| Interruption of work | Flush all equipment thoroughly with International GTA007. All unused paint must be stored in tightly closed containers. |
Partly filled containers may develop skinning and/or increased viscosity during storage. Strain the paint before use.
| Cleaning | All equipment should be cleaned immediately after use with International thinner. Flushing spray equipment periodically during daily work is good practice. Cleaning frequency depends on the volume sprayed, temperature, spraying time, including delays, and other factors. |
|---|
All surplus paint and empty containers must be disposed of in accordance with the relevant local laws/regulations.
The anti-corrosion performance of coatings applied over hand-prepared steel is directly related to the degree of surface preparation and the dry film thickness of the coating system.
To ensure good anti-corrosion performance, apply multiple coats on hand-prepared steel surfaces, with a dry film thickness of at least 150 µm (6 mils).
When overcoating with Interprime 198, the minimum overcoating interval can be short. When overcoating with epoxy or polyurethane topcoats, the minimum overcoating interval is 16 hours at 25 °C (77 °F). Consult International Paint Protective Coatings for details.
When overcoating with epoxy or polyurethane, attention must be paid to the dry film thickness specification to ensure proper curing time; this product should not be applied too thick.
The product is not suitable for severe corrosive environments, or heavily pitted or contaminated steel.
Interprime 198 is not suitable as a barrier coating to upgrade aged chlorinated rubber or vinyl coatings.
For marine environments, the paint system and overcoating interval may need adjustment. Paint systems with Interprime 198 are not suitable for immersion.
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
Interprime 198 is normally used on blast-cleaned or hand/power tool cleaned steel surfaces. However, it is also suitable for application over the following primers, and can be used as a repair paint over existing convertible coatings.
Intergard 251; Intergard 269. The following topcoats are recommended for use with Interprime 198: Intercryl 530, Interfine 629HS, Intergard 740, Interlac 665, Interplus 770, Interplus 880, Interthane 990, Interthane 990E. For other suitable primers/topcoats, consult International Paint.
