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
- Clean the surface by removing all dirt, dust, grease, peeling paint or other wall covering.
- Repair any cracks, chips, holes or other surface defects. Be sure to sand rough areas smooth.
- For wood, fill in any dents or cracks in the surface with wood filler or wood putty. Filler absorbs stain; putty does not.
- Caulk all open cracks around windows and doors, soffits and fascia.
- Remove light switch-plates and fixtures that attach to the painting surface.
- 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.
With any airless sprayer, a certain amount of overspray (the paint that misses the intended surface) is expected.
- Protect surfaces that shouldn't be painted from overspray. When exterior painting, always take note of wind conditions before spraying.
- Cover or remove all baseboards, furniture, shutters, windows, shrubs, etc.
- Use a spray shield as necessary.
- 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.
