EXAM – The Worx Nitro 20V Cordless Paint Sprayer beats the heck out of brush painting in certain applications. Now was the perfect time to review the Worx Nitro paint sprayer. My wife wanted to do some paint jobs and here is the Worx Nitro Sprayer for review. Last month I primed my under deck trellis with several brushes (since the work is ruining them) and I still bear the emotional scars. The work was long, slow and tedious. The Worx Nitro 20V Cordless Paint Sprayer made me forget about that priming job and helped me do the topcoat in 3 hours instead of two days.

Setup and Setup

I’m late for the paintbrush game. The Worx Nitro 20V cordless paint sprayer was my first experience with a paint sprayer. It was a clear case of a textbook that needed to be studied. I charged the batteries while I was reading. I also practiced making all possible settings and adjustments on the sprayer, changing spray nozzles and cleaning.

I practiced using water. My neighbors wondered why I was varnishing a pine tree but I brushed off their concerns. I got a lot of spray on my face but the water is lighter than the paint and my training day was too windy to paint but fine for training.

Tests and observations

My wife and I have an arrangement that has worked very well for 40 years. She’s the Colors Committee, and I’m Labour. The color committee decided that the truss below deck should be brick colored, like our deck steps. I think it’s a better look than white.

Last summer I used a water sealant on the trellis, so now I had to use an oil-based white primer that accepts latex topcoat paint. $60 a gallon! Ugh.

The paint doesn’t bother me. It’s the prep and the cleanup that I hate. I painted the exterior of our 2 story house, twice, using paint brushes and a 32 foot ladder. I’ve used rollers and brushes on rooms, moldings, a shed and decks. The Worx Nitro sprayer was a pleasure to use, minimized drudgery and was easy to clean up afterwards.

I did this amount of paint on one battery. The white area shows where it broke. I put the battery in the charger, inserted a fresh battery and continued to work. Or Worx.

The rough mesh below deck looked great when I was done, but my result on the dresser indicates I need more practice. It’s a “sacrificial piece” that we’ll be giving away soon to make everything better than his rough, yellow, 30-year-old brushwork.

Some say the Worx Nitro 20V cordless paint sprayer “doesn’t have enough pressure, so it takes longer to get a job done.” I was very happy to see minimal overspray which saves me paint, joint issues and cleanup, so pressure was not an issue for this beginner painter. I did not increase the pressure from the factory setting.

I confess that I don’t know how to choose a sprayer tip width beyond the obvious. A thin paint or other material probably goes best with a small diameter nib and a thicker material benefits from larger diameter nibs. I used the red tip for both of my jobs, but wonder if the dresser would have looked better if I had used a larger diameter tip and/or increased the spray pressure. The viscosity of the paint was similar for both of my jobs, which is why I didn’t change the tip for the chest.

The main thing I knew, but learned even better, is that regular sweeps of the sprayer from an appropriate distance will help achieve a more even appearance of topcoats after drying. It’s probably on an old stone carving somewhere.

Cleaning consists only of removing paint from exterior surfaces of the Worx Nitro sprayer and removing all paint from internal components. For both of my jobs, I washed the internal parts with a garden hose, then soaked all parts except the handle (which should not be submerged) in a bucket of water for about an hour, then I did a final cleaning of the parts.

I think it’s almost impossible to keep the exterior of a paint sprayer factory in pristine condition. There were very fine splatters of paint on the outer parts of the sprayer of the two colors I used. The paint can is completely clean, but I wasted no effort in cleaning the tiny stains from the body of the sprayer. If they don’t scratch with a fingernail after soaking for an hour, I call them “experimental evidence”.


This cleaning attachment screws onto the body of the sprayer like the jar does and cleans paint from internal works.

Brick-colored paint has stained the top seam of the foam paint can shown here. It seals the paint can when the can is screwed into the sprayer. Here it was totally clean but still showed some brownish marks. Worx support said it didn’t matter and seals could be purchased later if needed.

For some reason the white paint stuck to the interior surfaces of the sprayer more than the brick color. The paints were of the same brand but were different products. Along with a toothbrush, I got the Worx Nitro 20V Cordless Paint Sprayer clean and ready for storage.

What I like

      • Easy to use once you get the hang of it
      • Easy to clean
      • Light, until you add the paint, then still not super heavy.

What I would change

      • I don’t have any recommendations other than recommending everyone buy an extra battery or two unless you’re doing some really quick paint jobs.

Final Thoughts

I will always use rollers and brushes for interior paint jobs, mostly because I’m not a pro with a paint sprayer. But I have 250 feet of new garden fence that will soon need to be stained or painted and I plan to take a few days with the Worx Nitro 20V cordless paint sprayer to do this job – As soon as the committee decides on the color.
