The performance of the product depends on the degree of surface preparation. The surface to be coated shall be clean, dry and free from contamination. Before painting, all surfaces shall be assessed and prepared in accordance with ISO 8504:2000.
Accumulated dirt and soluble salts must be removed. Accumulated dirt is generally best removed with a dry bristle brush. Soluble salts should be removed by fresh water washing.
For immersion service, Intertuf 262 must be applied to surfaces blast cleaned to Sa2½ (ISO 8501-1:2007) or SSPC SP10. However, for atmospheric exposure, Intertuf 262 should be applied to surfaces blast cleaned to Sa2½ (ISO 8501-1:2007) or at least SSPC SP6.
Surface defects exposed by blast cleaning must be ground, filled or treated by a suitable method.
Recommended surface roughness 50–75 µm (2–3 mils).
Hand or power tool preparation: clean to St 2 (ISO 8501-1:2007) or SSPC-SP2 minimum.
Note: all mill scale shall be removed; areas not suitably treated by chipping or needle gun shall be spot-blasted to Sa2 (ISO 8501-1:2007) or SSPC SP6 as a minimum. This generally applies to grade C or D rusting.
Ultra-high-pressure water jetting/wet blasting may be applied over surfaces prepared to Sa2 (ISO 8501-1:2007) or SSPC SP6, with flash rust allowed to a standard not lower than HB2M (see the International Paint hydroblasting standard). In some cases, application over damp surfaces is possible. For more information, contact International Paint.
Aged coatings: Intertuf 262 is suitable for overcoating aged coatings in limited areas; the coating shall be intact and firmly adherent. Loose or flaking coatings shall be removed to a sound film edge. Glossy topcoats may require light abrasion to provide a "key" for adhesion. For more information, see the 'Properties' section.
Intertuf 262 may be applied to freshly applied zinc silicate shop-primed steel. If the shop primer is extensively damaged or excessively corroded,
| the surface shall be sweep blasted. | Other types of shop primer not suitable for overcoating shall be fully sweep blasted. |
|---|
Weld seams and damaged areas shall be blast cleaned to Sa2 (ISO 8501-1:2007) or SSPC-SP6.
For zinc-rich primers, remove weld spatter where necessary and grind welds and sharp edges; weld seams and damaged areas shall be blast cleaned to Sa2 (ISO 8501-1:2007) or SSPC-SP6. Shop primer or other primer surfaces shall be clean and dry, free from contaminants (e.g. oil, grease, soluble contaminants, etc.). Apply Intertuf 262 within the appropriate overcoating interval (refer to the relevant product overcoating interval data).
Before overcoating, ensure the zinc-rich primer is fully cured and the surface is dry and free from zinc salts.

|---|---|
| Cleaner | Use a cleaning solvent that complies with local regulations. Consult the local representative for specific recommendations. |
| Interruption of work | Do not allow paint to remain in hoses, spray guns or spray equipment. Thoroughly flush all equipment with International thinner. Once a paint unit has been mixed, it shall not be resealed. If the application is interrupted for an extended period, remixing the components before resuming application is recommended. |
| Cleaning | All equipment shall be cleaned with International thinner immediately after use. Periodic flushing of spray equipment during application is also recommended. The frequency of cleaning depends on the quantity sprayed, temperature and time, including all interruptions. |
When Intertuf 262 is applied by brush or roller, multiple coats are necessary to achieve the specified total system dry film thickness.
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.
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point. If Intertuf 262 is applied in a confined maintenance environment, adequate ventilation shall be ensured.
Like all epoxy paints, Intertuf 262 will chalk and fade when exposed to the atmosphere. However, this phenomenon will not affect the anti-corrosive performance.
For water immersion service, surface preparation to a minimum standard of Sa2½ (ISO 8501-1:2007) or SSPC-SP10, followed by multiple coats of Intertuf 262, with a minimum total dry film thickness of 250 µm (10 mils).
If salt water is used during wet blasting, the treated surface must be thoroughly washed with fresh water before applying Intertuf 262. Light rust spotting on freshly blasted surfaces is permitted and preferable to a surface that is too damp. Puddles, standing water and accumulated water must be removed.
Intertuf 262 is suitable for overcoating intact, aged epoxy and polyurethane systems. However, the product is not recommended for thermoplastic coatings such as chlorinated rubber and vinyl. Please contact International Paint for advice.
Gloss and surface smoothness depend on the application method. Mixing different application methods should be avoided where possible. Premature exposure to standing water may cause colour change, particularly in dark-coloured paints.
When used as part of an approved scheme, the coating holds the following certificates: • USDA accepted for food contact in federally inspected meat and poultry plants.
Approved by the Chief Resident Inspector, Intertuf 262 complies with Petrobras N-2851.
Although the low-molecular-weight reactive additive becomes part of the film when cured under normal ambient conditions, analysis by EPA Method 24 shows that it also affects the VOC value.
Low-temperature performance: when low-temperature curing is required, use KHA414 for low-temperature curing. Drying times and overcoating data are as follows.
| Pot life | -7°C (20°F) | 5°C (41°F) | 25°C (77°F) |
| 12 h | 8 h | 4 h |
