A two-component, low-VOC, high-build modified epoxy barrier coating providing long-term protection in a single coat. It continues curing when immersed in water and has high cathodic disbondment resistance.
The low surface tolerance of Interzone 954 allows it to be applied to various carbon steel surface conditions in maintenance and repair work.
Primarily designed for maintenance of offshore splash zones; it continues curing under immersion and is suitable for tidal and wave environments. Can be applied to re-oxidized and slightly damp surfaces. Interzone 954 is also widely used in other corrosive environments, such as paper mills, chemical plants, docks and sluice gates.
Use with a suitable aggregate as part of a non-skid deck coating system.

The performance of the product depends on the degree of surface preparation. The surface to be coated shall be clean, dry and free from contamination. Before painting, all surfaces shall be assessed and prepared in accordance with ISO 8504:2000.
Accumulated dirt and soluble salts must be removed. Accumulated dirt is generally best removed with a dry bristle brush. Soluble salts should be removed by fresh water washing.
Oil and grease must be removed in accordance with the SSPC-SP1 solvent cleaning standard.
Blasting: blast-clean to Sa 2½ (ISO 8501-1:2007) or SSPC-SP6. If oxidation occurs between blasting and application of Interzone 954, re-blast the surface to the specified visual standard.
Surface defects exposed by abrasive blasting must be ground, filled or treated by another suitable method.
Recommended surface roughness 50–75 µm (2–3 mils).
Hand or power tool preparation
| For atmospheric service, clean by hand or power tool to at least St 3 (ISO 8501-1:2007) or SSPC-SP3. | In particular, all mill scale shall be removed; areas that cannot be fully cleaned by chipping or needle gun shall be spot-blasted to at least Sa2 (ISO 8501-1:2007) or SSPC-SP6. This usually applies to grade C or D rusting. |
|---|
Ultra-high-pressure water jetting/wet blasting may be applied over surfaces prepared to Sa2 (ISO 8501-1:2007) or SSPC SP6, with flash rust allowed to a standard not lower than HB2M (see the International Paint hydroblasting standard). In some cases, application over damp surfaces is possible. For more information, contact International Paint.
Aged coatings: Interzone 954 is suitable for recoating over certain sound, intact aged coatings. To ensure compatibility, a test patch and evaluation are required.

|---|---|
| Interruption of work | Do not leave paint in hoses, spray guns or spray equipment. Flush all equipment thoroughly with International thinner. |
Mixed paint should not be resealed. If work is interrupted for too long, mix a fresh batch of paint for application.
| 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.
Apply by airless spray to achieve the maximum film thickness per coat. Application methods other than airless spray cannot achieve the required film thickness. With air spray, several cross coats are required to achieve the maximum film thickness. At low or high temperatures, special application techniques may be required to achieve the maximum film thickness.
When applying Interzone 954 by brush or roller, multiple coats are necessary to reach the specified total system dry film thickness.
The surface temperature must be at least 3 °C (5 °F) above the dew point. Throughout application and curing, ensure adequate ventilation and air flow to avoid 'dead spots', especially in confined spaces. In special cases, if recoating is required and the film has cured under low-temperature, high-humidity conditions, ensure no amine salts are present before applying the topcoat. When ambient conditions allow, e.g. good ventilation and air flow, GTA220 can still be used (max 5%). Condensation on the surface during or after application causes a dull surface and a poor film. Premature exposure to standing water causes colour change, especially with dark colours.
As with all epoxy systems, the product may chalk and discolour under exterior exposure. Where a durable decorative finish with good gloss and colour retention is required, apply the recommended topcoat.
For tidal application on docks, piles, etc., Interzone 954 can be immersed after 30 minutes. This causes whitening of dark-coloured paint, but does not affect the final anticorrosive performance.
For atmospheric service applied directly to steel, a minimum dry film thickness of 350 µm (14 mils) per coat is required; for immersion service, a minimum of 450 µm (18 mils) is recommended. Both can be applied in a single coat by airless spray. Interzone 954 is suitable for buried steel structures (Im3 per ISO 12944-2). By adding GMA 132 (crushed flint) aggregate, Interzone 954 can be used as an anti-slip deck system, applied over a suitably primed surface. The typical thickness is 500–1000 µm (20–40 mils). Use a suitable large-nozzle spray gun (e.g. Sagola 429 or an air spray gun with a 5–10 mm nozzle). Small areas can be trowelled or roller-applied. Alternatively, broadcast techniques can be used. For details, consult International Industrial Coatings.
Interzone 954 can be used with sacrificial anode and impressed current cathodic protection systems.

Do not apply when the steel temperature is below 4 °C (39 °F).
Note: VOC values are typical and for guidance only. They may vary with colour and general production tolerances.
Although the low-molecular-weight reactive additive becomes part of the film when cured under normal ambient conditions, analysis by EPA Method 24 shows that it also affects the VOC value.
Interzone 954 is normally applied over bare steel prepared by dry abrasive blasting, wet abrasive blasting or ultra-high-pressure water blasting.
