Remove oil and grease in accordance with SSPC-SP1 solvent cleaning.
Blast cleaning to Sa2 (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.
Repair of damaged areas: damaged areas must be blast-cleaned to Sa 2½ (ISO 8501-1:2007) or SSPC-SP6 (blast-clean to SSPC-SP10 for optimum performance). If local areas cannot be blasted, power tool cleaning to St 3 (ISO 8501-1:2007) is allowed. Only after surface preparation can the primer be applied. Before applying HI-ALKYD 1041 Fast-drying Alkyd Primer, ensure the surface to be coated is clean and dry, and apply within the specified recoat interval (refer to the relevant product instructions).
Other surfaces: if the coating is to be applied to other substrates, consult the Protective Coatings Division of Nippon Paint Industrial Coatings.
Application is not recommended when the ambient temperature is below 5 °C or above 50 °C, or relative humidity exceeds 85%; steel
The temperature should be at least 3 °C above the dew point of the surrounding air.

Note: the surface should be free of chalking and contamination before recoating. When the film has been exposed outdoors too long, or the surface is smooth or contaminated, recoat adhesion is adversely affected, so the surface must be roughened, 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, coating system, and prior hand or mechanical preparation conditions.
The following primers/topcoats are recommended for use with HI-ALKYD 1041 Fast-drying Alkyd Primer
Topcoat
Select the coating system according to the specific requirements; refer to the product manual or contact Nippon Paint for professional guidance.
Packaging: set, weight 25 kg, pack size 18 L. Storage: shelf life (from production date): 12 months (at 25 °C). Store in a cool, dry, ventilated warehouse meeting fire safety requirements, with warehouse temperature not exceeding 40 °C. 12 months at 25 °C from the production date. The above is the minimum shelf life; inspect before continued use thereafter.
Due to the nature of alkyd products, skinning tends to occur after long-term storage. If skinning occurs, simply remove the skin; the product can still be used normally.
