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.
Oil and grease must be removed in accordance with the SSPC-SP1 solvent cleaning standard.
Blast cleaning: abrasive blast clean to Sa 2½ (ISO 8501-1:2007) or SSPC-SP10. If oxidation occurs between blast cleaning and application of Interzone 1000, the surface should be re-blasted to the specified visual standard.
Surface defects exposed during abrasive blasting must be ground, filled or treated by a suitable method.
Recommended angular surface roughness of 75–100 µm (3–4 mils).
Shop-primed steel: Interzone 1000 can be applied over an approved anticorrosive primer. The primer surface must be dry and free from any contaminants; Interzone 1000 must be applied within the specified recoating interval (see the relevant product data sheet).
Cracked or damaged areas should be prepared to the specified standard (e.g. abrasive blast cleaning to Sa 2½ (ISO 8501-1:2007) or SSPC-SP10, or power tool cleaning to SSPC-SP11), and the primer repaired before applying Interzone 1000.
Weld seams and damaged areas should be blast cleaned to Sa 2½ (ISO 8501-1:2007) or SSPC-SP10. If the shop primer shows extensive damage or widespread scattered damage, overall sweep blasting may be required.
| Mixing | This product is supplied in two containers forming one unit. Mix the two components in the specified ratio in one operation. Once mixed, use within the specified pot life. |

(1) Stir the base (Component A) with a power mixer.
(2) Mix all of the curing agent (Component B) with the base (Component A) and stir thoroughly with a power mixer.
Avoid prolonged stirring, as the heat generated greatly shortens the pot life.

|---|---|
| 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 | 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 appropriate local laws/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.
The high content of glass flakes in the coating effectively prevents the total dry film thickness of the paint system from falling below 400 µm (16 mil). Two coats achieve ideal performance in severe environments, each coat 500-750 µm (20-30 mil), followed by full spark testing.
The temperature of the surface to be coated must be at least 3 °C (5 °F) above the dew point.
This product does not cure adequately below 5 °C (41 °F). For optimum performance, curing should take place above 10 °C (50 °F).
Over-application of Interzone 1000 will extend the minimum recoating time and handling time, adversely affecting long-term recoating performance.
Gloss and surface evenness depend on the application method. Avoid mixing different application methods as far as possible.
Underwater curing is slower. Some colour changes may occur.
Like all epoxy coatings, Interzone 1000 chalks and fades when exposed to the atmosphere. However, this does not affect anticorrosive performance. In this case, due to the large amount of lamellar glass flakes, chalking slows after the surface epoxy layer is removed.
The intercoat adhesion on aged Interzone 1000 is reduced relative to that on a fresh coating, but still meets the needs of the intended use.
When a durable decorative surface with good gloss and colour retention is required, a recommended topcoat should be applied. However, decorative topcoats do not have the same abrasion resistance as Interzone 1000.
By modification with GMA 132 (crushed flint) aggregate, Interzone 1000 can be used as an anti-skid deck paint system, applied over a suitably primed surface. The typical thickness is between 500-1000 µm (20-40 mil). It is best applied with 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 applied by trowelling or rolling. Alternatively, broadcast application can be used. Consult International Paint Industrial Coatings for details.
Interzone 1000 can be used with sacrificial anode and impressed current cathodic protection systems. Interzone 1000 is suitable for buried steel structures (Im3 in accordance with ISO 12944-2). A modified version of Interzone 1000 is available for cold climates to provide better application properties. Consult International Paint Industrial Coatings for more information.
Note: the VOC value given is based on the maximum possible value for the product and 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 1000 is normally applied directly to suitably prepared steel, but the following primers are recommended: Intergard 269, Interline 982. The following topcoats are recommended for use with Interzone 1000: Interfine 629HS, Intergard 740, Interthane 990, Interthane 990E, Interzone 954. For other suitable primers/topcoats, consult International Paint Industrial Coatings.
