Surface preparation and application must be carried out in accordance with the recommendations given in the AKZONOBEL Chartek 8E application specification manual.
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 8504:2000.
Blast cleaning: Chartek 8E is normally suitable for surfaces blast cleaned to Sa 2½ (ISO 8501-1:2007) or SSPC-SP10 and coated with a suitable primer.
The selected primer or primer system must be on the AkzoNobel qualified primer list. The preferred primer is an epoxy type specified at no more than 75 µm (3 mils). A two-coat primer system, such as epoxy zinc-rich and tie coat, may also be used; the combined specified thickness should not exceed 110 µm (4.5 mils).
| Mixing | For trowel application, the individual components should be stored at 35 °C (95 °F) and thoroughly power-stirred before mixing. |
|---|---|
| Mixing ratio | Always mix the whole unit of coating, refer to the Chartek 8E application specification manual |
| Pot life | 10°C (50°F) | 20°C (68°F) | 40°C (104°F) |
| 120 min | 105 min | 25 min |
The pot life value refers to unthinned trowel application performance after pre-warming to 35 °C (95 °F) before stirring. If the material is not pre-warmed, the pot life is extended but mixing is more difficult. The pot life does not apply to two-pump airless spray application, because the product is mixed only in the static mixer near the gun. Refer to the product application manual.
| Plural-component airless spray | Recommended and preferred equipment | AKZONOBEL-approved heated twin-pump equipment; no thinner is required. |
| Suitable for airless spray | Recommended | Airless spray with a compression ratio of at least 68:1 is recommended (obtaining International Protective |
Coatings approval)
| Trowel application | Suitable | Refer to the Chartek 8E application specification manual |
| Thinner | International GTA123 | For premixed application and trowel application only — refer to the Chartek 8E application specification manual |
| Cleaner | International GTA007 |
|---|---|
| Interruption of work | Do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with International GTA123. Mixed paint shall not be re-sealed. If work is interrupted for a long period, use freshly mixed paint when work resumes. |
| 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 relevant local laws/regulations.
Throughout application, the following conditions must be present (or created):
| Minimum air temperature | 10°C (50°F) |
|---|---|
| Maximum humidity | 85% |
| Surface temperature | At least 3 °C (5 °F) above the dew point of the surrounding air. |
| General | All surfaces to be coated must be clean, dry and free of contaminants. |
Immediately before application.
Chartek 8E should be applied by spray to ensure complete wetting of the substrate. If the application is not only by spray, the first coat should be thoroughly applied by trowel and roller to achieve this.
The best self-recoating time for Chartek 8E is after the minimum self-recoating interval has been reached, or before the coating has any chance of being contaminated.
Mesh installation: some applications require no reinforcement mesh. If reinforcement mesh is required, AkzoNobel HK-1 or HK-2 carbon fibre mesh should be installed in accordance with the specific fire protection design, following the detailed instructions in the Chartek 8E application specification manual. Seek specific advice from AKZONOBEL regarding mesh requirements.
After mesh application (if applicable), continue spraying Chartek 8E to the required thickness. Only equipment approved by the AKZONOBEL Chartek 8E application specification manual and technical service representatives may be used.
Applicator certification: only companies holding the qualified applicator certificate issued by AKZONOBEL may apply Chartek 8E. These companies must be documented before application.
Chartek 8E application must be carried out by the application company using qualified employees trained in the correct application procedures. At a minimum, site supervisors and QA/QC personnel must hold individual qualifications and have attended the AKZONOBEL Chartek applicator training course. This is the minimum requirement and must be documented in writing before application.
Inspection and quality assurance. This is the applicator's responsibility and must at least follow the procedures specified in the AkzoNobel Chartek QC manual. Technical service. Available from AkzoNobel and should be coordinated to be present at start of work. The applicator is responsible for ensuring AkzoNobel is notified of the start date.
Other surface preparation: for some project-specific environments, AKZONOBEL has developed procedures for wet blasting, ultra-high-pressure water blasting (water jetting) and power tool cleaning. Consult AKZONOBEL for specific recommendations.
Maximum surface operating temperature. At service temperatures above 120 °C (>248 °F), Intertherm 7050 shall be used as a suitable thermal barrier between the substrate and Chartek 8E.
Note: the application density values are typical and for guidance only. Refer to the Chartek 8E application specification manual.
Chartek 8E is designed for application to substrates that have been properly prepared and coated with a suitable primer. The following primers may be used with Chartek 8E:
| Intergard 269 | Intershield 300 |
|---|---|
| Intergard 2511 | Intershield 4000USP |
| Intergard 2575 | Interzinc 52E/Intergard 269, Intergard 7500. Normally, a topcoat is applied over Chartek 8E to meet the owner's colour scheme and topcoat requirements. |
The following topcoats are recommended for use with Chartek 8E: Interfine 2080, Interthane 990, Interzone 954
