Fluid Processing & Techniques: Tip Selection, Thinning, and Application by Coating

Fluid Processing & Techniques covers what happens between the bucket and the surface: which tip to run, when and how to thin, and how the method changes with the coating and the job.

  • Tip Selection: Airless spray tip size charts, 515 vs 517, and tip choices for oil-based paint and cabinet finishing.
  • Thinning and Viscosity: Thinning latex paint for an airless sprayer, and handling high-solids and silicone roof coatings.
  • Application by Job Type: Deck staining, drywall finishing, stucco, fireproofing, athletic field marking, and road striping.
