General Tips

  • Read your instruction manual
  • Choose the right spray tip
  • Mask off everything you don’t want painted and cover floors with drop sheets
  • Practice your spray painting technique with water before you paint
  • If necessary, strain the paint so it doesn’t clog the spray gun
  • Keep the paint sprayer 20-25cm from the surface
  • Start painting from the top and work your way down
  • Stop paint blotches by moving the gun before you press the trigger and after you release it
  • Use even side-to-side or up and down strokes
  • Work in sections, as far as you can comfortably reach
  • To spray paint corners, turn the gun and spray directly into it
  • For exterior jobs, avoid spraying on windy days
  • Wear safety clothing - long-sleeve shirt, safety goggles and a respiratory mask
  • Clean your spray painter as soon as you’ve finished using it
