Safety Notice

Stay alert, take proper safety precautions, and be aware of potential hazards when operating spray equipment.

Protect yourself by wearing gloves, safety glasses/goggles, a spray sock (hood), a hat, appropriate footwear, and dust masks. Ensure there is adequate ventilation.

Turn off appliances when you are painting near them. (In sprayer operation manual, see Safety Precautions). Always refer to the specific safety instructions and procedures for the spray equipment you are using.

Getting Started/Preparation

  • After preparing the surface for spray painting, take a few minutes to carefully observe the job being sprayed and identify any surfaces that you do not want to be coated with paint or overspray.
  • Any surface areas where overspray is not desired should be protected by masking these surfaces with masking tape and other types of masking film.
  • Masking tape is the most common material used for masking before spray painting. Masking tape is available in different widths and in different qualities.
  • Be careful not to damage the edges of the masking tape rolls, as this can cause problems when removing the tape from the roll and problems getting a straight edge of the mask.
  • Larger areas can be covered with commercially available cut sheets, newspapers, masking paper, or rolls of film.
  • To make the job easier, make sure that all masking material is held securely in place and can’t spill out once you start spray painting.
  • If you are using particularly water-based paints or working outdoors or in humid environments, normal masking tape cannot be left in place long after being exposed to moisture, otherwise, normal masking tape will become extremely difficult to remove.
  • More durable masking tape products are available that are more waterproof and can be left in place for longer periods.
  • Before applying any masking tape, clean and dust the surfaces to ensure good tape adhesion.
  • Unroll some masking tape and stick it where you want to start, then unroll it completely before re-sticking the masking tape, if masking straight lines, make the tape line as straight as possible.
  • Press firmly along the tape to make sure it is secure. A large volume of air is generated when air sprays and airless sprays create high speeds that can expel poorly adhered masking materials from the surfaces to be protected.
  • If you’re working in a corner, put a wide knife firmly on the tape and tear to finish cleanly in that corner.
  • Good quality masking tapes stretch and generally can be easily worked around sharp corners and curves. If it is too difficult or slow to follow the curve correctly, drop the tape onto the surface to be painted, then lightly use a sharp cutting knife to cut the tape so that only the surfaces you want to protect are covered.
  • Taking the time to properly mask before starting any spray paint job will make the entire spray job easier to clean and will achieve a better end result.
  • Be careful when removing the masking tape while the paint is still soft, as scratches may occur in the coating of the newly spray-painted surface. Likewise, don’t wait too long to remove all masking after the paint has dried, otherwise, removal may be difficult.

Clean Up

  • Allow the paint to dry for a considerable time before removing the tape from the trim. This will result in crisp, clean lines.
  • Remove all covers from furniture and other areas.
  • Replace any light fixtures you removed and move furniture or other items into place.
  • Clean your airless paint sprayer after each use. Follow the instructions in the user manual for Power Flush cleaning with water-based materials or use the bucket cleaning method, if applicable. For more information, see the Power Flush video or refer to the Sprayer Operation Manual.
  • Put furniture or other items back in place.

Spray painting is a messy job. Both paint companies and professionals recommend that you wear a mask at all times. This Half-face 3M respirator is a good choice. … If you are not wearing a mask, these VOCs can cause irritation.

How do you cover a room for painting?

Consider covering a room with a plastic sheet and then covering it with a canvas dropcloth. This is a better option for absorbing paint splatters and makes the room look larger. Use masking tape to cover hinges and other difficult-to-remove hardware.

How do you tape a room before painting?

Start Taping the Room

Begin to frame the area you want to paint. Place tape in a straight line on the wall. To ensure that there are no gaps between the pieces, overlap them a bit. Also, be careful not to stretch or pull the tape while you apply it. This could cause it to leak.
