Airless Painting Surface Preparation

Proper surface preparation (prep) is essential for a high quality finish. The amount of surface prep required depends on the surface condition and the material being applied. You'll always have better success if you spray onto a clean, dry surface.

Clean & Repair Before Spraying

This is where the real work in painting is... get out the elbow grease

  1. Clean the surface by removing all dirt, dust, grease, peeling paint or other wall covering.
  2. Repair any cracks, chips, holes or other surface defects. Be sure to sand rough areas smooth.
  3. For wood, fill in any dents or cracks in the surface with wood filler or wood putty. Filler absorbs stain; putty does not.
  4. Caulk all open cracks around windows and doors, soffits and fascia.
  5. Remove light switch-plates and fixtures that attach to the painting surface.
  6. Use primer on all bare wood and on areas that are stained and will be painted.

When interior painting, always spray in well-ventilated areas.

Protect Surfaces

With any airless sprayer, a certain amount of overspray (the paint that misses the intended surface) is expected.

  1. Protect surfaces that shouldn't be painted from overspray. When exterior painting, always take note of wind conditions before spraying.
  2. Cover or remove all baseboards, furniture, shutters, windows, shrubs, etc.
  3. Use a spray shield as necessary.
  4. For interior painting, always spray in well ventilated areas. Use safety glasses/goggles, mask, and spray sock.

Always consult your material supplier and operation manual for specific job requirements.
