Surface prep

Preparing the surfaces is the most important part of any painting project. For best results, it is recommended that interior walls first be washed clean using TSP (Trisodium Phosphate) and allowed to dry. For exterior painting, it is recommended to wash the surface with a pressure washer and cleaning solution if needed. With a clean dry surface, repair any cracks, chips, and holes before spraying. You may also want to sand rough areas for smoother finishes.

With any airless project, a certain amount of overspray should be expected. To protect surfaces from overspray, you should always spend a few minutes preparing the surroundings. Before spraying, make sure you cover all baseboards and protect any furniture, shutters, or windows. Remember, when painting outdoors, always take careful note of wind directions.

Good surface prep is a vital step to any painting process and you can find some excellent pointers by visiting the website of your favorite paint supplier.

Airless spray technique

For even paint distribution and quality results, follow these basic spray techniques:

  • Keep spray gun about 12 inches from the surface.
  • For best coverage, use a long, continuous motion – start your motion before triggering gun and continue your motion after the gun trigger is released.
  • Overlap your spray pattern by about 50% - Simply aim the spray gun on your next pass at the edge of the previous painted area.
