Suggested Tools and Equipment for Painting Your Home

  • Graco, Magnum or TrueCoat paint spray guns (visit the Paint Sprayer category page to compare models)
  • Paints or varnishes of your choice
  • Spray nozzles: a wider spray pattern for large surfaces and a narrow size for smaller surfaces (see nozzle selector )
  • Empty buckets for priming the sprayer and cleaning (two needed)
  • Sticks or other paint stirring utensils (disposable, you won't be able to reuse them)
  • Sandpaper: 100-300 grit
  • Tack cloth
  • Paint strainer bag: helps prevent tip clogs and provides a better finish
  • Tarps, drop cloths, or plastic sheeting
  • Masking tape
  • Touch-up brush
  • Pump Armor storage fluid (see Pump Armor product details)
  • Cleaning rags
  • Stiff nylon cleaning brushes.

Preparing to paint the exterior of your home with airless equipment

Set up a work area away from other surfaces where overspray can fall and cover the lawn or pavement in that area with tarps or protective cloth.

Place the furniture on the protective cloth and remove the hardware.

Thoroughly clean the furniture with a scrubbing sponge and cleaning agent or a pressure washer equipped with its low power wash nozzle. Rinse well and allow to dry.

Repair any cracks or damage. Fill holes with caulk as needed and then lightly sand the entire surface. Start with 100 grit sandpaper to remove loose paint and increase to 300 grit to smooth the surface and increase paint adhesion. Finally, wipe the furniture with an antistatic cloth to remove sanding dust.

Using a spray gun for painting

Select the spray nozzle that best suits the paint or stain you are using and the surface to be sprayed. In general, a nozzle with a narrower spray pattern of 8 inches wide and an orifice size of .013 will give you the best control. Make sure the tip orifice size does not exceed the maximum capacity of your sprayer (see tip information).

If you are using paint from multiple containers, mix it in an empty 5-gallon container to ensure uniform color even if there are slight color differences between individual paint cans. When spraying lighter materials such as stains, select the lowest pressure setting that will allow you to maintain a good spray pattern. Lower pressure settings will give you better control and a finer finish.

Work from the top down, spraying in long, even strokes and following the grain of the wood. Keep the spray tip about 12 inches from the surface you are spraying. Pay special attention when spraying in tight spaces, such as between boards, and overlap each successive spray by approximately 50%.

After painting, clean up and tidy up!

Allow paint or stain to dry for a considerable time; then remove all shrubbery, bushes, plants and surface coverings. Drying times are always variable when dealing with exteriors, as heat and humidity greatly affect drying times. Consult the manuals of the material used or better still, talk to us and ask us for advice; we will be happy to help you and give you the precise information you need.

Replace any consumables you have used. Yes, we always tend to put this off for another day, but the reality is that this almost never happens and the next time you want to use your Graco painting equipment, you may not be able to start the job because of a missing bucket, or filter, or utensil that you have used on previous jobs and have used or consumed. Do it now and your equipment will always be ready and able to do its best on your semi-professional painting jobs.

Replace any lightfixtures you have removed and put furniture or other items back in place. Do this with care and attention to detail; sometimes fatigue or the length of the task causes this part to be neglected, but taking it slow and respecting the newly painted areas will make the job look professional and excellent. Take your time!

Clean your airless painting equipment (or airless guns) after each use. Follow the instructions in your owner's manual for Power Flush cleaning with water-based materials or use the bucket cleaning method, if applicable. For more information, refer to the Power Flush video or refer to the Sprayer Operation Manual.


Safety for Household Airless Spray Guns and Equipment

Whenever operating spray equipment, take proper safety precautions, stay alert and be aware of potential hazards. Wear protective equipment such as gloves, safety glasses, hooded coveralls, hat or light helmet, proper footwear, and (critical!) dust masks and respirators. Make sure there is adequate ventilation.

If you are painting near electrical appliances, turn them off (See Safety Precautions in the Sprayer Operating Manual). Always refer to the specific instructions and safety procedures for the spray equipment you are using.
