Hand held spray guns are great tools for any decorating task, but what are the top reasons for using a paint spray gun?

Speed

If you have limited time on a decorating project, a paint sprayer is a great option. Using a paint spray gun is much faster than traditional paint brushes or rollers. This is because the small paint particles that come out of the spray gun produce a rapid full paint coverage of an area. This is particularly good for tricky areas, such as wall corners or tight spaces that rollers can't normally reach.

Fluid Feed Methods for Spray Finishing
  • Suction Feed - material is drawn from fluid container by creating venturi across top of syphon tube fitted in cup.
  • Gravity Feed - as name suggests, material is gravity fed from cup positioned above the spray gun.
  • Pressure Feed - material is fed to spray guns via pressure pot or remote cup under pressure. Pressure is applied by air within pot to force material up hoses to spray nozzle.

Atomisation of Paint
Paint is atomised by high pressure, high volume air bombarding paint coming out of fluid tip, which breaks it up into cloudy spray pattern. A solid coat of material is achieved by overcoating several times in various directions.

Advantages
  • Very good finish achieved
  • Good control ability
  • You can use small amounts of material
Disadvantages
  • Poor transfer efficiency: 60% waste, i.e. overspray
  • Slow application rate
  • Can only spray low viscosity paints
