Question: can you spray a room
Document: Prior spray painting experience was nonexistent. My first experience was with the Rockler HVLP spray gun . And I amazed on how easy it was to adjust the spray and the coverage was perfect. I will continue to use the spray for my future home projects (inside and outside)  .
This might be a great tool but I haven't figured that out yet because the instruction manual is so bad. It give very little useful information. It seems like they could have put forth a lot more effort into giving instructions on how to use the Spray Gun. I am having to learn by trial and error (very frustrating).
It has hardly any over spray so wall prepping is at a minimum. It'll do 4 X 4 foot patterns and one quart of paint will do one 8 X 12 wall easily. It cleans up very easy and the Spray Head is the only area that needs a small long brush to clean it- I find an Acid Brush works best.
I'm lazy about turning off the motor all the time so when I'm out of paint I just remove the Air Hose from the Spray Head. This keeps air from blowing into the sprayer nozzle where the existing remnant paint is sitting and drying out while you're refilling the quart cup. I usually have 2 spray cups (about $11 each) filled up with paint and ready to go.
Purchased this unit to save on paint over my regular spray gun. I was not satisfied with the unit. I tried spraying diluted latex and all it did was splatter the paint. I tried it again without water, but it did not work as well either. I have not tried it using any other types of spraying materials .I will go back and use my regular spray gun and compressor.
Virtually NO overspray. The only time I had blowback was when I intentionally sprayed into an enclosed box to see how sever the blowback was. Very easy to use system.As other reviewers have noted the &#34;instruction manual&#34; is pretty much a waste of paper. &#34;Do not spray flammable materials&#34;, with other instructions on how to thin polyurethane for spraying.Nowhere on the unit does it say &#34;Rockler&#34;.
After a single flush everything is pretty clean. If you can't finish it on site then leave water in the quart cup and reattach it. This will keep any leftover paint moist for later cleaning. When you get home disassemble the spray nozzle and Quart cup and grab an Acid Brush and an old tooth brush. If it's badly gummed up let it soak in a bucket of water overnight. The worst area to clean is the where the pickup tube assembles into the Sprayer Head.
Don't add too much water because the paint will tend to run or the air pressure coming out the Sprayer nozzle will blow air grooves in the paint on the wall. I personally like a thicker application so I usually add  cup of water per gallon to thin it. Just adjust the needle screw to the thickness you need. That's it. Pretty easy...FYI- most paints tend to clog up the spray nozzle if you have it running without the quart cup attached.
I have used so many other sprayers trying to get a smoothe finish. I've used compressor driven hvlp spray guns and an hvlp system from the blue big box store made by Graco. I have a 20 gallon 6cfm compressor but it seems that once it started running it would never catch up until I was done spraying. The system by graco was used for deck stain and some painting. It did good but I didn't feel I could trust it with polyurethane.
I am not a great DIY'er but I try to do everything I can. When I needed to paint new doors and mouldings I couldnt imagine doing by hand so I researched and bought this. Painting only ranks behind plumbing in most hated for me.It works even better than I had hoped. I dont follow the rules about thinning, I spray outside, sometimes in the breeze and somehow the finish is perfect. I sprayed a cabinet door to see how it would look and it looks factory!
Answer: yes
