Tips for Best Results when Spraying


How to Paint Indoors With a Paint Sprayer

Indoor paint spraying may seem like a difficult task, but with the right planning it's actually a simple DIY. Use this "Indoor Spraying 101" to simplify the painting process, while saving you money versus hiring professional painters, and time versus painting with a brush.



Indoor paint spraying is easy if you prepare the room first.

  • Start by remove small furniture and items from the room.
  • Place larger furniture that cannot be removed in the center of the room, and cover it with plastic.
  • Remove as many fixtures from the room as you can.
  • Remove and store light switch and outlet plates, and cover the switches and outlets with painter’s or masking tape.
  • Cover blinds, light fixtures and ceiling fans with plastic. Tip: tape the screws to the switch plates so they don’t get lost.

Tape and mask area


How to mask doors, windows, flooring, trim and other areas you don't want to accidentally paint spray.

  • Mask off the trim, doors and windows with paper or plastic taped in place.
  • Leave a crisp line between the trim and wall by running a putty knife along the edge of the tape where it meets the wall.
  • Cover the floor with plastic and tape it down at the edges of the room so that it overlaps the paper on the baseboard molding.
  • Overlap sheets of plastic across the middle of the floor if necessary.

Pro Tip: Masking allows you to paint faster, don't skip this step!

Masking off


How you treat the ceiling will depend on your project.

  • If you are painting it the same color as the rest of the room, leave it exposed. Then, after you paint the walls, go back and paint the ceiling.
  • If you’re not painting the ceiling, climb a ladder and mask off the edges with tape and paper, then cover the ceiling's interior sections with paper or plastic secured by tape.

Taping the ceiling


Repairing the walls before painting will ensure you get the best paint spray finish.

  • Patch all holes and cracks with drywall joint compound and sand them to a smooth surface.
  • Ensuring these areas are perfectly smooth is paramount to a quality result.
  • If the walls are fairly clean, wipe them down with a damp rag
  • If they are quite dirty, wash them with a solution of water and trisodium phosphate or a substitute.
  • After cleaning, remember to ensure the walls are entirely dry before paint spraying

Washing the Walls


Inspecting your work with a bright light is an absolute must because a paint sprayer finish is so smooth, every defect you miss when preparing the walls will show up in the final finish. And the use of a work light will help you find any flaws.

  • Shining the light at various angles will highlight ridges and depressions that may be difficult to see on a white, or light colored background.
  • Look for blotchy areas that may need an extra coat of primer.
  • A quick scuff-sand with 150-grit sandpaper just before you spray the final coat will ensure the best results.

Shine a light to make sure the walls are prepared


Using a paint sprayer will apply a smooth, professional-looking finish to your walls. Although spraying won’t produce streaks like rolling, drips can happen.

  • To avoid drips, set the spray tip to a wide pattern using the FLEXiO’s red lever located on the tip.
  • Hold the paint spray gun no closer to the wall than 6-inches.
  • To ensure even coverage, keep the sprayer moving at a steady speed and avoid arcing at the end of your stroke.
  • After your careful preparation and precise spraying, let the paint thoroughly dry.
  • Lastly, put your room back together to relax and enjoy the beauty of your handiwork.
