Surface preparation and application shall be carried out in accordance with the recommendations given in the AKZONOBEL Chartek 8823 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 8823 is generally suitable for surfaces blast cleaned to Sa2½ (ISO8501-1:2007) 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 | 1.25 parts : 1 part by weight (refer to Chartek 8823 application specification manual) |
| Pot life | 10°C (50°F) | 25°C (77°F) | 40°C (104°F) |
| 30 min | 30 min |
The pot life value refers to the trowel application performance of the undiluted material heated to 35 °C (95 °F) before mixing. If the material is not preheated, the pot life will be extended, but mixing will be more difficult. The pot life is not applicable to two-pump airless spray application, because the product is only mixed in a static mixer near the spray gun. Refer to the product application manual.
| Plural-component airless spray | Recommended and preferred equipment | Heated two-pump equipment approved by AkzoNobel. No thinner required |
| Suitable for airless spray | N/A | |
| Trowel application | Suitable | Refer to the Chartek 8823 application specification manual |
| Thinner | International GTA123 | For premixed application and trowel application only — refer to the Chartek 8823 application specification manual |
| Cleaner | International GTA220S | Select a cleaner complying with local regulations. For specific usage recommendations, consult the local |
representative.
| Interruption of work | Do not leave material in hoses, guns or spray equipment. Flush all equipment thoroughly with International GTA220S. Once mixed, paint should not be resealed; if work is interrupted for too long, mix a fresh batch for application. |
|---|---|
| Cleaning | Clean all equipment immediately after use with International GTA220S. Flushing spray equipment periodically during application is recommended. Cleaning frequency depends on the volume sprayed, temperature and time, including all interruptions. |
Surplus paint and empty containers must be disposed of in accordance with the relevant local regulations.
Throughout the entire application period, the following conditions must be met (or created): minimum air temperature: 10 °C (50 °F); maximum humidity: 85%; surface temperature: at least 3 °C (5 °F) above the surrounding ambient air dew point. General: the surface must be clean, dry and free from contaminants, and immediately ready for coating application. Chartek 8823 shall be applied by spray to ensure the substrate is completely wetted. If application is not only by spray, the first coat should be thoroughly
| trowel and roller applied to achieve this. | The ideal self-recoating time for Chartek 8823 is after reaching the minimum recoating interval and before any possible contamination. |

When applying a decorative topcoat over Chartek 8823, the following recoating intervals apply: minimum maximum
| 10°C (50°F) | 8 h, 14 days |
|---|---|
| 25°C (77°F) | 2 h 14 days |
| 40°C (104°F) | 2 h 14 days mesh installation. Charlok mesh installation shall be in accordance with the specific fire protection design; for details, please refer to the Chartek 8823 user manual. For mesh requirements, please consult AKZONOBEL for details. |
Equipment: only equipment approved by the AKZONOBEL Chartek 8823 application specification manual and technical service representatives shall be used.
Applicator certification: only companies with qualified applicator status issued by AKZONOBEL are permitted to apply Chartek 8823. These companies must provide documentary evidence before application.
Chartek 8823 application shall be carried out by the application company using personnel trained and qualified in the correct application procedures. At a minimum, site supervisors and QA/QC personnel shall 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 jetting and power tool preparation.
Maximum surface operating temperature: when the temperature is between 80–120 °C (176–248 °F), a suitable insulation layer, such as Intertherm 7050, shall be used between the substrate and Chartek 8823.
Chartek 8823 is designed for application to substrates with properly prepared surfaces and coated with a suitable primer. The following primers can be used with Chartek 8823: Interdur 8816, Interdur 8817. Typically, a topcoat is applied over Chartek 8823 to meet the owner's colour scheme and topcoat requirements. The following topcoat is recommended for use with Chartek 8823: Interdur 8860.
