Surface preparation and application must be carried out in accordance with the recommendations given in the AKZONOBEL Chartek 2218E 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 2218E 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 | 1.21 parts : 1 part by weight (refer to the Chartek 2218E application specification manual) |
| Pot life | 10°C (50°F) | 20°C (68°F) | 40°C (104°F) |
| 30 min | 30 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 | Refer to the Chartek 2218E application specification manual |
| Suitable for airless spray | Recommended | |
| Trowel application | Suitable | |
| Thinner | International GTA123 | For premixed application and trowel application only — refer to the Chartek 2218E application specification manual |
Cleaner
| 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 | Clean all equipment immediately after use with International thinner. 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 application, the following conditions must be present (or created):
| Minimum air temperature | -10°C (14°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 2218E 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 ideal self-recoating time for Chartek 2218E is after the minimum recoating interval has been reached, before it can be subjected to any contamination.
When overcoating Chartek 2218E with a decorative topcoat, 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. *For Interthane 990, the maximum overcoating interval is 6 months. |
Mesh installation (if applicable): Charlok mesh installation should follow the specific fire protection design; refer to the Chartek 2218E application manual.
After mesh application, continue spraying Chartek 2218E to the required film thickness. Only equipment approved by the AKZONOBEL Chartek 2218E 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 2218E. These companies must be documented before application.
Chartek 2218E 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 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.
Maximum surface service temperature: when the temperature is between 80-120 °C (176-248 °F), a suitable thermal insulation layer, such as Intertherm 7050, should be used between the substrate and Chartek 2218E.
Note: the application density values are typical and for guidance only. Refer to the Chartek 2218E application specification manual.
| Chartek 2218E 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 2218E: |
|---|---|
| Intergard 251HS | Intergard 269 |
| Intergard 7500 | Intershield 300 |
| Intershield 4000USP | Interzinc 52E/Intergard 269. Normally, a topcoat is applied over Chartek 2218E to meet the owner's colour scheme and topcoat requirements. AKZONOBEL Protective Coatings recommends the use of a topcoat in all exterior service environments. The following topcoats are recommended for use with Chartek 2218E: |
| Interthane 990 | Interfine 2080HS |
