Surface preparation and application shall be carried out in accordance with the recommendations given in the AkzoNobel Chartek 1709 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 8504:2019.
Blast cleaning: Chartek 1709 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 | 2.5 Component A:1 Component B by weight (refer to Chartek 1709 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 two-pump equipment; no thinner is required. |
|---|---|
| Suitable for airless spray | Recommended: use AkzoNobel-approved modified airless spray equipment, minimum 68:1. Normally, a maximum of 5% by volume solvent thinning is used. |
| Trowel application | Suitable | Refer to the Chartek 1709 Application Specification Manual |
| Thinner | International GTA123 | For premixed application and trowel application only — refer to the Chartek 1709 application specification manual |
| Cleaner | International GTA007 |
|---|---|
| Interruption of work | Do not leave paint in hoses, spray guns or spray equipment. Thoroughly flush all equipment with International GTA123. |
Mixed paint shall not be resealed. If work is suspended for an extended 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.
Apply Chartek 1709 by spray to ensure complete wetting of the substrate. If application involves more than spraying, the first coat shall be thoroughly trowel-applied and rolled to achieve this.
The preferred self-recoat time for Chartek 1709 is after the minimum self-recoat interval has been reached, or before the coating has any opportunity to become contaminated.
When Chartek 1709 is recoated with the recommended topcoat, the recoat intervals are as follows;
Minimum, maximum*
| 10°C (50°F) | 24 h; 7 days |
|---|---|
| 25°C (77°F) | 18 h; 7 days |
| 40°C (104°F) | 6 h 4 days (*When Interthane 990 is used, the maximum recoat interval is 6 months) Mesh installation (if applicable): some applications do not require any reinforcing mesh. If reinforcing mesh is required, install AkzoNobel HK-1 or HK-2 carbon fibre mesh in accordance with the specific fire protection design and the detailed instructions in the Chartek 1709 Application Specification Manual. For mesh requirements, seek specific advice from AkzoNobel. |
After mesh installation, continue spraying Chartek 1709 to the required film thickness. Only equipment approved in the AkzoNobel Chartek 1709 Application Specification Manual and by technical service representatives shall be used.
Applicator certification: only companies holding a qualified applicator certificate issued by AkzoNobel may apply Chartek 1709. These companies must provide documentary evidence before application.
Chartek 1709 application shall be carried out by the applicator company using qualified personnel trained 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 a 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 is 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.
Consult AkzoNobel for specific advice.
Maximum surface operating temperature: when the service temperature is greater than 120 °C (>248 °F), Intertherm 7050 shall be used between the substrate and Chartek 1709 as a suitable thermal barrier.
Note: application density values are typical and for guidance only. Refer to the Chartek 1709 Application Specification Manual.
Chartek 1709 is designed for application to substrates with properly prepared surfaces and a suitable primer. The following primers may be used with Chartek 1709:
| Intergard 269 | Intergard 7500 Interzinc 52/Intergard 269 |
|---|---|
| Intergard 2511 | Intershield 300 |
| Intergard 2575 | Intershield 4000USP: Chartek 1709 is usually topcoated to meet the owner's colour scheme and topcoat requirements. AkzoNobel Protective Coatings recommends a topcoat in all external service environments. |
The following topcoats are recommended for use with Chartek 1709:
| Interfine 2080* | Interzone 954Interthane 990* Available by region |
