Conventional spraying is supposed to be the most common application method among painters working in the light industrial coatings area.

Our technical consultants at SELEMIX®, based on many years of experience with conventional spray equipment, have taken this as a reason to put together a short list of best practice.

It is important to understand that during the conventional spray application, paint is atomised by compressed air into an aerosol and is then transferred onto the surface to be painted.

To gain the best outcome, it is essential to ensure that the setup is done correctly:

  1. Mix the paint to the recommendations on the paint manufacturer’s technical data sheet (TDS), thinning to the correct viscosity.
  2. Use correct nozzle / tip size recommended on the paint TDS.
  3. Use a pressure gauge on the spraygun to measure the air pressure. The pressure should be in line with the spraygun manufacturer’s recommendations (normally 2-3 bar).
  4. Check the spray pattern before spraying. If the fan is not correct and even, it normally indicates a blocked hole in the air cap, or a damaged nozzle or air cap.
  5. Adjust the size of the fan for the job. For large flat areas, the fan should be fully open.
  6. Clean the gun thoroughly after use and replace any damaged or worn out parts as required.

We are confident that using the above checklist will empower the professional painter to achieve excellent results when using Selemix products with a conventional spray equipment.
