Blast clean to Sa 21⁄2 BS EN ISO 8501-1:2007 (SSPC-SP10/ NACE2). Average surface profile in the range 50-75 microns (2-3mils). Ensure surfaces to be coated are clean, dry and free from all surface contamination. Manually prepared surfaces should be prepared to a minimum standard of St 3 BS EN ISO 8501-1:2007 (SSPC-SP3) at the time of coating. 

The following is a guide. Changes in pressures and tip sizes may be needed for proper spray characteristics. Always purge spray equipment before use with listed reducer. Any reduction must be compliant with existing VOC regulations and compatible with the existing environmental and application conditions.

Airless Spray

• Nozzle Size: 0.33 - 0.45mm (15-19 thou)
• Fan Angle: 40°
• Operating Pressure: 197kg/cm² (2800 psi)

The airless spray details given above are intended as a guide only. Details such as fluid hose length and diameter, paint temperature and job shape and size all have an effect on the spray tip and operating pressure chosen. However, the operating pressure should be the lowest possible consistent with satisfactory atomisation. As conditions will vary from job to job, it is the applicators' responsibility to ensure that the equipment in use has been set up to give the best results.

Conventional Spray

• Nozzle Size: 1.27mm (50 thou)
• Atomising Pressure: 2.8kg/cm² (40 psi)

The details of atomising pressure, fluid pressure and nozzle size are given as a guide. It may be found that slight variations of pressure will provide optimum atomisation in some circumstances according to the set up in use. Atomising air pressure depends on the air cap in use and the fluid pressure depends on the length of line and direction of feed i.e. horizontal or vertical.

Brush

The material is suitable for brush application. Application of more than one coat may be necessary to give equivalent dry film thickness to a single spray applied coat.
