Interfine 629 High-performance Topcoat is an acrylic coating for use as a topcoat. Typical applications include (but are not limited to) shopping centres and sports venues, tank exteriors, handrails, and general steel structures and equipment requiring good appearance and easy cleaning. Two-component, high-gloss acrylic topcoat with the following characteristics: isocyanate-free, safer to use; good gloss and colour retention in harsh environments; cures at temperatures as low as 2°C; simple maintenance at recoating; fast-drying and rapid handling. Under such environmental conditions, ensure maximum thickness is achieved in a single coat. Parameters on this page: dry film thickness 60–80 µm (2.4–3.2 mil), theoretical spreading rate 6.70 m²/L, number of components two-component.

All surfaces to be coated must be clean, dry and free of contamination. Before painting, all surfaces must be assessed and prepared in accordance with ISO 8504:2000.
Oil and grease must be removed in accordance with the SSPC-SP1 solvent cleaning standard.
Accumulated dust and soluble salts shall be removed by rinsing with clean water.
Interfine 629 shall always be applied over the recommended anti-corrosive primer. The primer surface shall be dry and free from any contaminants; Interfine 629 shall be applied within the specified recoat interval (refer to the relevant product data sheet).
Areas of breakdown or damage shall be prepared to the grade specified in the standards (e.g. Sa2½ (ISO 8501-1:2007), SSPC SP6 or SSPC SP11) and the primer repaired before application of Interfine 629.
| Mixing | This product is supplied in two containers as one unit. Always mix the entire unit in the specified ratio. Once mixed, use within the specified pot life. |

| Interruption of work | Do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with International GTA713. |
Once mixed, paint should not be resealed. If work is interrupted for too long, mix a fresh batch for application.
| Cleaning | All equipment shall be cleaned with International GTA 713 immediately after use. Periodically flushing spray equipment during the daily work is good practice. The frequency of cleaning depends on the quantity sprayed, temperature, spraying time and interruptions. |

All surplus paint and empty containers must be disposed of in accordance with the relevant local laws/regulations.
A wide range of colours can be produced using the Chromascan system. If the original surface is clean, dry and free from contamination, Interfine 629 can be recoated with itself indefinitely.
Under high-temperature and windy conditions, GTA713 thinner shall be used to improve flow and reduce dry spray. Under such conditions, ensure maximum thickness is achieved in a single coat.
Interfine 629 shall not be applied as a thin film. Under damp conditions, the film must always exceed 100 µm. Under high-temperature conditions, application at the upper end of the film thickness range is recommended.
Product gloss and surface finish depend on the application method. Where possible, avoid mixing different application methods.
The following primers/intermediate coats are recommended for Interfine 629:
| Intercure 200 | Intercure 420 |
|---|---|
| Intergard 251 | Intergard 269 |
| Intergard 475 au | Intergard 475HS |
