Intergard 410 Epoxy Intermediate Coat/Topcoat is an epoxy coating used as an intermediate coat. Intergard 410 can be used as a primer for high-weather-resistance topcoats, as a pigmented intermediate coat/tie coat, and also as a topcoat where high decorative finish is not required. It is a high-build, high-performance, two-component epoxy coating with excellent chemical resistance and abrasion resistance. The primer should be Intergard 740 or Intergard 410, thinned with International GTA220 at approximately 10-20% by volume. Parameters on this page: volume solids 60% ± 3% (depending on colour), dry film thickness 100-150 µm (4-6 mil), theoretical spreading rate 4.80 m²/L.

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.
Blast cleaning: abrasive blast clean to Sa 2½ (ISO 8501-1:2007) or SSPC-SP10. If oxidation has occurred between blast cleaning and application of Intergard 410, the surface must be re-blasted to the specified visual standard.
Surface defects exposed during abrasive blasting must be ground, filled or treated by a suitable method.
Primed surfaces: the primer surface must be dry and free from any contamination, and Intergard 410 must be applied within the specified recoating interval (refer to the relevant product data sheet).
Areas of breakdown and damage must be prepared to the specified standard (e.g. Sa 2½ (ISO 8501-1:2007) or SSPC-SP6 blast standard, or SSPC-SP11 hand/power tool standard), and these areas must be touched up with primer before applying Intergard 410.
Welds and damaged areas of shop-primed steel must be blast cleaned to Sa 2½ (ISO 8501-1:2007) or SSPC-SP10. If the shop primer has sustained extensive or widely dispersed breakdown, a full sweep blast may be required.
For substrates primed with zinc-rich primer, ensure that the primer surface is clean, dry and free from any contaminants and zinc salts before applying Intergard 410. Ensure that the zinc-rich primer has fully cured before overcoating.

|---|---|
| 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 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 delays, and other factors. |
All surplus paint and empty containers must be disposed of in accordance with the appropriate local laws/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.
This product does not cure adequately below 5 °C (41 °F). For optimum performance, curing should take place above 10 °C (50 °F).
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point.
When applying Intergard 410 in confined spaces, ensure adequate ventilation.
As with all epoxy coatings, the product will chalk and fade when exposed to the atmosphere. This does not affect its anticorrosive performance. The actual chalking rate depends on the climatic conditions and is usually limited to a thin surface layer. If the chalked layer is exposed to UV light and intermittent high-velocity water washing, it will erode; only in this case does chalking reduce the anticorrosive performance of the coating.
For durable decorative surfaces requiring good gloss and colour retention, overcoat with the recommended topcoat.
Condensation on the surface during or after application will cause loss of gloss and a poor-quality film.
Premature exposure to standing water may cause colour change, especially for dark colours.
Intergard 410 is suitable as a protective system for concrete floors and walls with low traffic and mild chemical attack.
Before coating, concrete should cure for at least 28 days. The moisture content of the concrete should be below 6%. All surfaces must be clean, dry and free from curing compounds, release agents, trowelling compounds, surface hardeners, weathering products, grease, oil, dirt, old paint and loose or friable concrete. All cast or precast concrete must also be prepared by brush-off blast cleaning or acid etching to remove laitance. The primer should be Intergard 740 or Intergard 410, thinned with International GTA220 at approximately 10-20% by volume.
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.
Intergard 410 can be applied over a wide range of primer systems, including:
| Intercure 200 | Interplate 398 |
|---|---|
| Intercure 202 | Interzinc 12 (a mist coat or tie coat is recommended) |
| Intercure 420 | Interzinc 22 (a mist coat or tie coat is recommended) |
| Intercure 422 | Interzinc 42 |
| Intergard 251 | Interzinc 52 |
