Surface preparation and application shall be carried out per the recommendations in AkzoNobel's Chartek 2218 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 2218 is normally suitable for surfaces blast cleaned to Sa 2½ (ISO 8501-1:2007) or SSPC-SP10, overcoated with an appropriate 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 part : 1 part by weight (refer to the Chartek 2218 application specification manual) |
| Pot life | 10°C (50°F) | 20°C (68°F) | 40°C (104°F) |
| 25 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 | Heated two-pump equipment approved by AkzoNobel. No thinner required |
| Suitable for airless spray | Suitable for small areas | A modified airless spray unit of at least 68:1 is recommended, approved by Akzo |
Nobel. Normally solvent thinning up to 3% by volume.
| Trowel application | Suitable | Refer to the Chartek 2218 application specification manual |
| Thinner | International GTA123 | For premixed application and trowel application only — refer to the Chartek 2218 application specification manual |
| Cleaner | International GTA822 |
|---|---|
| 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.
Application: Chartek 2218 should be spray-applied to ensure the substrate is fully wetted. If application is not by spray alone, the first coat should be thoroughly trowelled and rolled to achieve this.
The ideal self-recoat time for Chartek 2218 is after reaching the minimum recoat interval and before any possible contamination.
When overcoating Chartek 2218 with a decorative topcoat, the following recoat 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): some fire ratings do not require reinforcing mesh. If reinforcing mesh is required, install Charlok or the carbon-fibre mesh HK-1 or HK-2 from AkzoNobel Protective Coatings, per the specific fire design and the Chartek 2218 application manual. Specific mesh requirements require specific advice from AkzoNobel Protective Coatings.
After mesh application, continue spraying Chartek 2218 to reach the required film thickness. Only equipment approved by AkzoNobel's Chartek 2218 application specification manual and technical service representatives may be used.
Applicator certification: only companies holding qualified-applicator certification issued by AkzoNobel may apply Chartek 2218. These companies must be documented before application.
Chartek 2218 application shall be carried out by the applicator company using qualified employees trained in the correct application procedure. At a minimum, site supervisors and QA/QC personnel shall hold individual qualification 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 operating temperature: at temperatures between 80–120 °C (176–248 °F), a suitable insulation layer, e.g. Intertherm 7050, shall be used between the substrate and Chartek 2218.
Note: applied density values are typical and for guidance only. Refer to the Chartek 2218 application specification manual.
Chartek 2218 is designed for application on substrates with correctly prepared surfaces overcoated with an appropriate primer. The following primers may be used with Chartek 2218:
| Intergard 269 | Intershield 4000USP |
|---|---|
| Intergard 7500 | Interzinc 52/Intergard 269, Intershield 300. Chartek 2218 is normally topcoated 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 2218:
| Interfine 2080* | Interzone 954, Interthane 990. *Available only in some regions. |
