All surfaces to be coated must be clean, dry and free of contamination. Before application, all surfaces must be assessed and prepared in accordance with ISO 8504:2000. Remove any oil and grease by solvent cleaning in accordance with SSPC-SP1.
For steel substrates in immersion, humid or high-temperature service, apply this product over a suitably primed surface blast cleaned to Sa 3 (ISO 8501-1:2007), SSPC-SP5 or NACE No.1. For dry or fume environments, blast cleaning to Sa 2½ (ISO 8501-1:2007), SSPC-SP10 or NACE No.2 is appropriate. Surface roughness must be at least 75 µm (3 mils).
Ceilcote 370HT Primer must be applied before oxidation of the steel occurs. If oxidation has occurred, the entire oxidized area shall be re-blast cleaned to the standard specified above.
Surface defects found during blasting must be ground, filled or treated by a suitable method.
The concrete substrate must be well cured before flooring, lining or coating application. Refer to the concrete surface preparation guide for further information.
| Mixing | Ceilcote 370HT Primer must be mixed and applied in accordance with the application instructions. The resin component of this material is supplied as a two-drum unit. Mix the entire supplied unit. Once mixed, the material must be used within its pot life. |

Do not mix more paint than can be used within the recommended pot life.

| Interruption of work | Do not leave material in hoses, guns or spray equipment. Flush all equipment thoroughly with Ceilcote T410 / International GTA203. Use immediately after mixing; if the pot life is exceeded, discard and remix. |
Once mixed, apply until all the mixed paint is used.
| Cleaning | Clean all equipment with Ceilcote T410 / International GTA203 immediately after use. Periodically flushing spray equipment during the working day is good practice. The frequency of cleaning depends on the quantity sprayed, temperature and elapsed time, including delays. |

All surplus material and empty containers must be disposed of in accordance with local laws and regulations.
Before using the relevant Ceilcote system, read the detailed Application Guide.
Before work begins, International Paint provides a precise system for dry film thickness and number of coats.
Although Ceilcote 370HT Primer has 100% reactivity, actual volume solids may be lower depending on application conditions. International recommends an estimated spreading rate value of 75%.
Typical thickness, primer: dry film thickness 50–125 µm (2–5 mil), equivalent to a wet film thickness of 67–167 µm (2.7–6.7 mil). For concrete (depending on its porosity), the recommended theoretical spreading rate is 7.5 m²/L (305 ft²/US gal). The main purpose of the primer is to seal the pores of the concrete, rather than to form a coating on it, so close attention to its film thickness is not required.
Base coat/topcoat (resin + powder): dry film thickness 1500 µm (60 mil), equivalent to a wet film thickness of 1765 µm (71 mil), with a theoretical consumption of 1 m²/L (40 ft²/US gal) of resin, adding S1 powder at 2.5 kg/m² (2 lb/ft²).
Impregnation layer (resin-impregnated glass fiber mat): 800 µm (32 mil), theoretical spreading rate 1.34 m²/L (50 ft²/US gal). Higher temperatures reduce shelf life. The shelf life of the product without added hardener and in well-sealed condition at 25°C (77°F) is 3 months. Do not store in sunlight. A refrigerator is recommended to lower the material temperature as low as possible, thereby extending shelf life and pot life during airless spray application. Material temperature rises during mixing; particular attention is required. Recommended storage temperature range: 8°C–19°C (46°F–66°F).
The surface temperature must be at least 3 °C (5 °F) above the dew point. Ensure adequate ventilation during application and curing. Dehumidification, air conditioning and/or heating equipment may be necessary to control the environment.
At all stages of application, the surface, air and paint temperatures must be between 10 °C (50 °F) and 43 °C (110 °F).
If airless spray is used, avoid over-thick application. For optimum performance, back-roll the coating to ensure close contact with the surface.
If the recoat interval is exceeded, wipe with styrene to confirm whether recoating is possible. If the surface feels “slightly tacky”, adhesion is acceptable. If it is not softened by styrene, sweep blast or mechanically abrade the surface to obtain a matt, rough surface. Primed surfaces must be dry and free of foreign matter before lining, coating or flooring.
For temperature limits for specific end uses, consult the International Paint Protective Coatings Division.
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.
Ceilcote 370HT Primer is designed for application to properly prepared substrates.
It is compatible with various Ceilcote linings. Consult International Paint for further advice.

This product is intended for professional applicators in industrial use only.
All work, including the application and use of this product, must comply with the relevant national standards, laws and regulations on safety, health and environmental protection.
During application and the subsequent drying period (for common drying times, see the product data sheet), provide adequate ventilation to keep solvent concentrations within safe limits and prevent fire and explosion. Forced ventilation is required in confined spaces. During application and drying, personal ventilation and respiratory protection (e.g. air-fed hood or suitable filter mask) must also be provided. Take the necessary measures to prevent skin and eye contact with the coating (e.g. protective clothing, gloves, goggles, mask, barrier cream).
Before use, read and follow the Material Safety Data Sheet and the Health and Safety section of the application procedure for this product (for two-component coatings, those of the base and curing agent).
If welding or cutting is performed on metal substrate previously coated with this product, dust and fumes will be released; use suitable personal protective equipment and local exhaust ventilation.
The specific safety measures depend on the application method and working environment. If these warnings or instructions are not fully understood or cannot be strictly observed, do not use the product and consult International Paint.
