All surfaces to be coated must be clean, dry and free of contaminants. Before painting, all surfaces must be assessed and prepared in accordance with ISO 8504:2000.
Where required, 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 Sa2½ (ISO 8501-1:2007) or SSPC-SP10. If oxidation occurs between blast cleaning and application of Interline 104, the surface shall be re-blast cleaned to the specified visual standard.
Surface defects exposed during abrasive blasting must be ground, filled or treated by a suitable method.
Recommended surface profile 30–50 µm (1.2–2 mils).
| Mixing | Interline 104 must be applied in accordance with International Paint's detailed "Application Procedure" for tank lining materials. |

Interline 104 is supplied in two parts, a paste component (Component A) and a liquid base component (Component B). The liquid base (Component B) shall be slowly added to the paste component (Component A) while stirring with a mechanical stirrer. The paste component shall not be added to the liquid component. The paint shall be filtered before application and kept under continuous agitation during spraying. Once a unit is mixed, it shall be used within the specified pot life.

| Cleaning | All equipment should be cleaned immediately after use with International GTA 803. 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. |
All surplus paint and empty containers must be disposed of in accordance with the appropriate local laws/regulations.
Before use, consult the detailed Interline 104 application procedure.
Interline 104 is normally specified as a one-coat system with a dry film thickness of 100 µm (4 mils). The exact system to achieve the total dry film thickness depends on the end-use requirements. Consult International Paint for advice on tank lining coating application systems.
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 surface temperature must always be maintained at least 3 °C (5 °F) above the dew point.
Application of Interline 104 is not recommended when the steel temperature is below 5 °C (41 °F) or above 40 °C (104 °F).
Ensure adequate ventilation when applying Interline 104 in confined spaces.
The minimum recoating interval depends on the relative humidity during curing. At relative humidity below 65%, the minimum recoating interval is usually at least 24 h, but is determined by the ambient temperature and relative humidity during application and curing.
At relative humidity below 40%, curing slows and humidity shall be increased by suitable means such as steam or water spraying.
Excessive film thickness or over-application of Interline 104 will cause cracking. Once cracking occurs, the affected areas must be completely removed by blasting and then recoated according to the original coating system.
After the final coat has cured hard, the dry film thickness of the coating system shall be measured with a suitable non-destructive magnetic thickness gauge to verify the average total thickness of the applied coats. The coating shall be free from any pinholes or other misses. The cured film must be free from puddling, sagging, drips, inclusions or other defects. All defects and faults shall be corrected. Repaired areas must be re-inspected and cured as specified before the final lining coat is placed in service. For suitable repair procedures, consult International Paint's Interline 104 application procedure.
Optimum resistance is achieved only after the film has fully cured. Curing depends on temperature, humidity and film thickness. To ensure full cure, it is recommended to rinse with fresh water before placing in service, following the detailed steps recommended in the Interline 104 application procedure.
The product holds the following specification approvals:
| • Food contact | - Complies with FDA regulations: liquid foods and dry foods. |
|---|
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
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.
Due to the low film thickness, when self-recoating with Interline 104 is required, the surface must be unweathered and freshly applied. The minimum dry film thickness of the subsequent Interline 104 coat shall be 50 µm (2 mils) to ensure good film formation.
Interline 104 shall only be self-recoated and must never be recoated with other products.
Consult International Paint to ensure Interline 104 is suitable for contact with the product to be stored.

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.
