i have a milwaukee airless/finish paint sprayer M4910-20. i have used it once and became frustrated. finish turned out ok but i brushed the rest of my doors. i really want to be able to use the sprayer but i need some advice, such as:
do you thin your paint and how much and with what do you thin with
do you use the hvlp or the airsprayer
what are the settings you are using when spraying
have you sprayed ploy, did you thin it, hvlp or airsprayer
i would appreciate all advice and hints. im really looking forward to being able to spray finishes but need a little direction. thank you all for your comments
Flotrol for latax and Penatrol for oil based are great products, they will make an average painter a pro. I suggest using these additives every time you spray.
Well I am a year late here but just purchased a HF HVLP gun to use or furniture restoring etc. The tip is a 1.4 and Ive been told to get 1.7 -2.0 for latex . I got tip the other day and I mixed up 10 oz.paint and 1 oz water and it was just a little on the thick side so added 1/2 oz to it and it spayed just like a rattle can. I found a site last night that I will forward to you on how to spray .Good spraying to you
I am a big fan of Charles Niel woodworking. If you go to his site e has some tips onn spraying you can watch for free. He is currently producing a new vidio that covers all the problems incountered with spray finishes, runs, blotches, fisheyes, etc. I don't know how to direct you to his site like the others but it is Charlesniel woodworking.com. This might help anyone who is interested. It has helped me.
What do you guys do for a "spray booth." That one website guy said he was in Texas and sprayed outside all the time. I am in SW PA, and I don't have that luxury. I got cold in the winter, humidity in the summer, a wife with super sensitivity (dear, what do you mean lacquer stinks?), and a basement shop in the garage.
I just started spaying and I live in wet NW and I can see right now that it will be many long awaited days to paint out side so I guess just drop some plastic down from overhead and spray inside
Rick, I live in the wet northwest as well (Oregon) and I do the same method as Jens above. Drop down some plastic and add some Air filtration and circulation to rid the vapors. Works however renders the shop useless until the finish dries. Using a paint mask is a must and should be used anyway especially in the lacguer spraying as it is dangerous stuff. Another word of caution when spraying lacquer, beware of any open flame or ignition sources such as any electrical spark from a light swith, air compressors or igniton of a water heater or pilot lights. The vapors from lacguers can be highly explosive as well as toxic.
I don't mind overspray on the floor, and I can turn an exhaust fan on, but the smell permeates the house. Some of the HVAC ductwork even runs through the garage. The furnace return air just sucks fumes through the crevices. No way to make that garage airtight.
Wifey gets a little upset even when I use a little primer. My heater has an open flame, and that causes more problems. Turning off the heater, and running the exhaust fan only helps a little. Ugh!
Rick I know what you mean. It is a problem unless you are fortunate enough to have a dedicated room for finish.
About the best solution that I have came up with is using a good hvlp gun and this will cut down the overspray problem however the odor still lingers. I use a small hvlp gun that is pressurized from a compressor for very small jobs but resort to a graco turbine gun for large jobs like kitchen cabinet sets. The turbine gun has less that 6 lbs of pressure and sprays heated air which helps the finish lay down flat and allows more finish to be applied in a shorter time thus cutting down the amount of time you are exposed to the vapor smells. I have even used this gun in occuppied homes to finish woodwork and will be pretty much odor free in about an hour. The big advantage to this is that is very little overspray and therefore you get more of your finish applied to the the surface of your project. Good luck as summer time is still aways off.
Doug, I just bought that book. Thanks for the recommendation.

I could get into why I never spray poly "varnish", HVLP versus air sprayer ect., save yourself a lot of grief and pick up a copy of "Understanding Wood Finishing" by Bob Flexner. This can be purchased as used on Amazon. This is not a full blown technique book, but cuts through all the crap on the internet and will dramatically reduce your frustration level, I promise. This is considered the "Finisher's Bible by many, me included. My best advice would be to read it, re read it, and keep it in your shop.
