Remove oil and grease in accordance with SSPC-SP1 solvent cleaning.
Abrasive blasting: blast clean to Sa2½ (ISO 8501-1:2007) or SSPC-SP6 (or SSPC-SP10 for better results). If the blasted surface oxidises before coating, it shall be re-prepared to the specified standard. Surface defects exposed after blasting shall be treated by grinding, filling or other suitable methods. The surface profile shall be 40–75 µm or above.
Shop-primed surfaces: the product may be used over unrusted inorganic zinc silicate shop primer; before coating, welds and damaged areas shall be blast-cleaned to Sa2½ (ISO 8501-1:2007) / SSPC-SP6 (or SSPC-SP10 for better results). If the shop primer shows extensive breakdown or heavy rusting, the whole surface shall be blast-cleaned.
Repair of damaged areas: damaged areas must be blast cleaned to Sa 2½ (ISO 8501-1:2007) or SSPC-SP6.
If blasting is not possible in local areas, mechanical grinding to St3 (ISO 8501-1:2007) is permitted. HI-EPOXY 1494 application may proceed only after surface preparation.
Prior to application of HI-EPOXY 1494, the surface to be coated shall be ensured clean and dry, and application must be carried out within the specified recoat interval (refer to the relevant product application instructions).
Other surfaces: if this coating is to be applied to other surfaces, consult the local Nippon Paint company for further information.
Application is not recommended above 45 °C ambient temperature or above 85% relative humidity; the steel temperature must be at least 3 °C above the dew point of the surrounding air.

Note: *Before overcoating, the surface shall be free of chalking and contamination, and shall be sealed where necessary. When the film has been exposed outdoors for a prolonged period with zinc salts or contamination on the surface, adhesion of the overcoat may be affected; therefore the film surface shall be abraded, sweep-blasted or high-pressure water-jetted to ensure adequate adhesion.
The data above are for guidance only. Actual recoat and drying times may be shorter or longer depending on film thickness, ventilation, humidity, the underlying coating system, and prior hand or mechanical preparation conditions.

Curing agent: 12 months (25 °C). Store in accordance with national regulations. Keep the product sealed in a dry, cool, well-ventilated store away from heat and sources of ignition. High temperatures shorten the storage period and may cause the paint to gel in the container. The above is the minimum shelf life; thereafter, testing is required to confirm the product is still usable.
