The performance of this product depends on the degree of surface preparation. All surfaces to be coated must be clean, dry and free of contamination. Before painting, all surfaces must be assessed in accordance with ISO 8504:2000
| assessed and prepared in accordance with the standard. | Accumulated dirt and soluble salts must be removed. Dirt is generally brushed off with a dry bristle brush. Soluble salts should be washed off with fresh water. |
|---|
Blast cleaning: blast clean steel surfaces to Sa2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation occurs between blast cleaning and application of Interseal 1052, re-blast the surface to the specified visual standard.
Surface defects exposed by blast cleaning must be ground, filled or treated by a suitable method.
Interseal 1052 is suitable for application over blast-cleaned surfaces that originally met the above standard but have been allowed to weather for 7-10 days under good shop conditions. The surface then degrades to Sa2, but shall be free from loose powdery deposits.
Hand or power tool preparation (applicable only to aluminium-pigmented products): hand or power tool clean to the minimum standard of St2 (ISO 8501-1:2007) or SSPC SP2.
Note: all mill scale must be removed; areas that cannot be suitably prepared by chipping or needle gun must be spot blast cleaned to Sa 2 (ISO 8501-1:2007) or SSPC-SP6 minimum. This generally applies to rust grades C or D of this standard.
Ultra-high pressure water jetting / wet blasting (applicable only to aluminium-pigmented products): can be applied to surfaces prepared to Sa2½ (ISO 8501-1:2007) or SSPC SP6, with flash rust not below HB2½M (refer to International Paint hydroblasting standard) or SB2½M (refer to International Paint slurry blasting standard). In some cases, application is also possible on damp surfaces. For further information, contact International Paint Industrial Coatings.
Welds and damaged areas of shop-primed steel structures must be blast cleaned to Sa 2½ (ISO 8501-1:2007) or SSPC-SP6.
If the shop primer shows large-scale breakdown, the entire area must be blast cleaned.

|---|---|
| Interruption of work | Do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with International thinner. |
Mixed paint should not be resealed. If work is interrupted for too long, mix a fresh batch of paint for application.
| 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 interruptions, and other factors. |

Surplus paint and empty containers must be disposed of in accordance with the relevant regional regulations.
Apply by airless spray to achieve the maximum film thickness per coat. Application methods other than airless spray cannot achieve the required film thickness. With air spray, several cross coats are required to achieve the maximum film thickness. At low or high temperatures, special application techniques may be required to achieve the maximum film thickness.
If Interseal 1052 is applied by brush or roller, multiple coats may be required to achieve the specified film thickness.
Spray application can achieve a dry film thickness of 75 µm; thinning with 5% by volume GTA220 is recommended.
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point.
Ensure adequate ventilation when applying Interseal 1052 in confined spaces.
Interseal 1052 is not designed for continuous immersion in water.
Condensation on the surface during or after application will cause loss of gloss and a poor-quality film.
Gloss and surface evenness depend on the application method. Avoid mixing different application methods as far as possible.
As with all epoxy paints, Interseal 1052 will chalk and fade on exposure to the atmosphere. This phenomenon does not affect anticorrosive performance.
For durable decorative surfaces requiring good gloss and colour retention, overcoat with the recommended topcoat.
A low-temperature curing agent is available to ensure fast curing below 5°C, but this curing agent may cause colour change or rapid gloss loss of the paint under natural conditions. The coating reaches hard dry in 26 h below 0°C, but the minimum recoat interval at 0°C and -5°C is 40 h and 48 h respectively. The coating can cure at -5°C, but curing time will be significantly extended. The product shall not be applied to substrates below 0°C where ice formation may occur.
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.

Interseal 1052 is normally applied directly to steel, but may also be applied over the following primers:
| Interzinc 52 | Interzinc 22 series, Interzinc 72. The following topcoats are recommended for use with Interseal 1052: |
|---|---|
| Intergard 345 | Interthane 870 |
