All surfaces to be coated must be clean, dry and free of contaminants. Before application, all surfaces must be assessed and prepared in accordance with ISO 8504:2019.
Where necessary, remove weld spatter and grind welds and sharp edges smooth. Oil and grease must be removed in accordance with the SSPC-SP1 solvent cleaning standard.
Abrasive blast clean to at least Sa 2.5 (ISO 8501-1:2007) or SSPC-SP10.
Recommended surface roughness 50–75 µm (2–3 mils).
Interline 1046 shall be applied before oxidation of the steel occurs. If oxidation has occurred, the oxidized areas shall be re-blasted to meet the above standard.
Surface defects exposed by blast cleaning must be ground, filled or treated by another suitable method.
Where permitted by local VOC regulations, Interline 1046 (10-15% thinned) may be applied as a primer before surface oxidation occurs, at a DFT of 80 µm (3.2 mil). Alternatively, dehumidification methods may be used to maintain the blasting standard.
Areas with cracks, damage, welds, and similar defects shall be pre-treated to the specified standard (such as Sa2½ (ISO 8501-1:2007) or SSPC SP10, or cleaned with power tools to Pt3 (JSRA SPSS:1984) or SSPC SP11).

|---|---|
| Interruption of work | Do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with International thinner. |
Once mixed, paint should not be resealed. If work is interrupted for too long, mix a fresh batch for application.
| Cleaning | All equipment should be cleaned immediately after use with International thinner. Flushing spray equipment periodically during the daily work is good working practice. Cleaning frequency depends on the volume sprayed, temperature and time spent, including delays. |

All surplus paint and empty containers must be disposed of in accordance with the appropriate local regulations/laws.
Interline 1046 shall not be applied over unapproved primers or old paint films, as this may interfere with static dissipation performance.
Interline 1046 is generally specified as a two-coat system, with a thickness of 125 µm (5 mil) per coat and a total system DFT of 250 µm (10 mil). The exact system for this total DFT depends on the requirements of the end use. Consult International Paint for specific recommendations on tank lining application.
When used as a primer at a DFT of 80 µm (3.2 mil), Interline 1046 can withstand blasting for up to 14 days in semi-protected environments such as tank interiors. If moisture is present on the surface, oxidation will occur and re-blasting is required. Alternatively, if the recoat interval is observed and all surfaces are properly cleaned and pre-treated, a full coat may be applied before recoating with Interline 1046.
At temperatures below 15°C (59°F), an induction time of 15 min is recommended after mixing and before application of Interline 1046.
To achieve the maximum film thickness in one coat, airless spray is the ideal method. Application methods other than airless spray cannot achieve the required film thickness. With conventional air spray, several cross coats are required to achieve the maximum film thickness. Brush and roller are recommended for small areas only.
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point.
After the final coat is fully cured, a suitable non-destructive magnetic thickness gauge shall be used to measure the DFT of the coating system to verify the average total applied system thickness. The coating system shall be free of pinholes or other misses. The cured film shall be free of runs, sags, drips, inclusions, or other defects. All deficiencies and defects shall be corrected. Repaired areas shall be retested and cured as specified before being placed into service.
The coating achieves ideal chemical resistance only after full cure. The degree of cure depends on temperature, humidity and film thickness. Generally, at 250 µm (10 mils) total dry film thickness, full cure and ideal chemical resistance are achieved in 7–10 days at 25 °C (77 °F) and 50% relative humidity. At higher temperatures, curing shortens proportionally; at lower temperatures, it lengthens.
For storage of cargoes above ambient temperature, consult International Paint for further detailed advice.
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
This is a self-overcoating coating and is not suitable for application over other primers. Interline 1046 shall only be recoated with itself and shall never be recoated with other products.

This product is intended for professional applicators in industrial use only.
All work, including the application and use of this product, must comply with the relevant national standards, laws and regulations on safety, health and environmental protection.
During application and the subsequent drying period, provide adequate ventilation to keep solvent concentrations within safe limits and prevent fire and explosion (for general drying times, see the product data sheet). Forced ventilation is required in confined spaces. During application and drying, personal ventilation and/or respiratory protection (e.g. air-fed hood or suitable filter mask) must also be provided. Take the necessary measures to prevent skin and eye contact with the coating (e.g. protective clothing, gloves, goggles, mask, barrier cream).
Before use, read and follow the Health and Safety section of the Material Safety Data Sheet and the application procedure for the product (for two-component coatings, those of the base and curing agent).
If welding or flame cutting is performed on metal substrate coated with this product, dust and fumes will be released; use suitable personal protective equipment and local exhaust ventilation.
The specific safety measures depend on the application method and working environment. If these warnings or instructions are not fully understood or cannot be strictly observed, do not use the product and consult the International Paint Protective Coatings division.
