spraying poly?
I would like to get a spray system for poly to save a lotta hassle
when finishing my (future) kitchen cabinets. Probably would steer away from Harbor Freight. I remeber Apollo and Fuji as two brands that folks liked. Using a foam brsuh to put 3 coats on each cabinet..., well, let's just say been there, done that, don't want to repeat. Having done a little research, via googling the rec posts mainly, I couldn't find the thread I sorta remembered that had some pretty good dialogue on this subject. What I found was HVLP is good. HVLP is bad for poly. Etc. What I'm looking for are recommendations of "systems" from folks who've used them. What would the folks who've had experience get (now that they are experienced) in a similar situation. I haven't used any sort of spray system but am willing to invest in a decent system. I have come to learn that cheap is often not worth the future hassles. Wouldn't mind if it could later be used for paint as well, but that's secondary. Another question that arises is, how hard is it to get the spraying technique down? Last but not least, how 'bout some resources where I can read up on how to use this thing Thanx Renata |

I've never regretted my decision, but it is pricey. I've sprayed poly, so I don't know why you are stating that HVLP for poly is "bad". I don't really like using poly, so I avoid it where possible. Practicing with tip sizes, thinning ratios, cap sizes, pressure setting, distance from tip to surface, speed and overlap should allow you to successfully spray just about any material out there. Two more variables: fluid and fan adjustment, on the gun. I've sprayed stains, poly, lacquer, water borne poly, even latex (you need a powerful HVLP to do that correctly). The one product that I didn't prefer spraying was shellac; I wipe it on instead of spraying. Probably I didn't thin it enough for spraying, but since I'm content with wiping it, I haven't don't additional research. You can read about using an HVLP until the cows come home, but ultimately you need to just get out there and PRACTICE. Don't practice on your projects! Dave |

Cheap plastic gun and it sounds like an Electrolux - but after some practice the finish is quite nice. |

I got this one at Harbor and it has worked well for me.
http://www.harborfreight.com/cpi/cta...emnumber=43430 As for longevity, I have sprayed more poly-u over the past two years since moving and it has worked well. I have done way better with it than I thought I ever would. Off the top of my head I have done... Oak Entertainment Center (BIG ONE !) Pine Columns x 3 African Produk Home Theater Finish Carpentry (columns, etc.) Several small pieces like plant stands (Oak) Oak Kitchen table The only warning I have to folks buying this gun, watch what you use to clean it ! The plastic cup didn't take Mineral Spirits too well over the long haul. CJ "Renata" wrote in message ...

I've been really happy with my Turbinaire HVLP system. Good system with good
accessories and gun. I've never had problems spraying poly, just thin with spirits, check your viscosity so you have the right tips on the gun and go. But have discovered I really prefer shooting water based finishes to keep the fumes down. McFeely's sells a water based lacquer called Crystal Lac that I really love. Extremely easy to work with. You can get a lot of coats on in a pretty short time and the finish is excellent. My 2 cents Gary in KC "Renata" wrote in message ...

Actually.....unles you have an air supplied respirator you don't want to
spray poly, unless maybe is a water born product, or if you have a quality spray booth. If you are considering an oil based poly you run the risk of exposure to isocynates. If you do spray use a head sock, long sleeve shirt and change clothes immediately between each coat and after you finish. A respirator is a must when using poly and make sure the cartridges are brand new. "Renata" wrote in message ... I would like to get a spray system for poly to save a lotta hassle |

A well-practised sprayer with a mediocre gun will get far better results than a novice with a $3000.00 Fabialucci* gun. I have sprayed one gawdawful amount of doors, panels, crown, kicks, cabinets etc. in my life and, at the risk of sounding cocky, I'm ALMOST all done making mistakes. G I recently bought a Husky (Home Depot) HVLP for just over CAN$ 130.00. That gun should be under US$ 100.00. I sprayed an 8-foot cherry headboard with MinWax Polycrylic with excellent results with the Husky. In my previous life, after literally thousands of litres of catalysed lacquers through a serious DeVilbiss Pro pot-fed system, I was pleasantly surprised. (Maybe The MinWax people don't talk about spraying Polycrylic because of legal issues with the Fresh Air Police.... it sprays just fine, right out of the can. Just don't shake the ca,,,,we don't want to spray bubbles. Without the air being connected, open the fluid metering adjustment by pulling the trigger, till you get a small stream of liquid flowing from the nozzle. You get that when the needle pulls back away into the nozzle opening it up for fluids to pass. THE nicest feature from a gravity fed gun. Now the job of the air, is to do two things. Blow the stream apart (atomize) into a mist, and transport that mist onto the work -piece. Start off with about 40 PSIg at the gun. Add the air so that you get a vertical stripe of paint (called 'the fan') about 6"- 8" in height when you hold your gun about 12" away from the target. Make sure you don't vary that distance as you move that 'stripe' from side to side covering the area you painting. Initially, you may want to spray just water just to see what happens when you twist what knob which way. The tricky part is moving the fan over the work in an even speed and even distance then with just enough overlap between sweeps not too wet in the middle of the previous pass and not too dry so that 'banding' shows up. Overlap is the practice part. And keep that gun pointed perpendicularly to the work and don't move it away from the work just because you're running out of arm. Do NOT follow an arc. You CANNOT use water base in just any gun. The needle and parts have to be stainless steel. I still like shooting some alcohol through the gun after my soapy warm-water cleanup, followed at the end with some soft mineral spirits, such as Varsol.... just enough to coat the parts. Use 3 coats. Re-coat when the previous coat is just dry (1-2 hours). If you plan on sanding between coats (sometimes nice to get rid of dirt or suicide bugs) wait 24 hours. *Don't bother DAGSing Fabialucci, as I made up the name illustrating a generic top-of-the-line device. |

I too have a Turbinaire and it works well. I think the 4 stage Fuji might have
a slightly better gun. There are many good systems out there. I have sprayed poly both oil and WB with good results. I think the only material a good HVLP might have some trouble with is latex. If you can find a spray course in your area I strongly suggest you take it. You will save days of learning and practicing on your own.

Jeff Jewitt, www.homesteadfinishing.com, has a special on Astuo HVLP
setups and several good forums and sells products to boot. I grew up with oil based products but have now switched to waterbased only. He has a teaching schedule posted of his site that may fit your need. Mike Marlow wrote: "JGS" wrote in message ... I too have a Turbinaire and it works well.

Everyone knows latex is not meant to be sprayed, but is a finish intended to be hand applied to woods like cherry, walnut,... If you can find a spray course in your area I strongly suggest you take it. You will save days of learning and practicing on your own. Cheers, JG If you can't find a course (that could be a hard thing to find in a given area), stop by a local auto body shop. Chat with the owner who is also the guy that does all the work if the shop is small enough, and ask him to show you painting techniques. Most would be happy to do so and you won't find a better teacher for how to properly shoot paints than an autobody guy. -- -Mike- |

Isocyanate appears to be the catalyst behind oil based polyurethane cross
linking and curing. "All polyurethane coating systems are produced by the isocyanate-polyaddition process in which isocyanates and suitable co-reactants are combined to produce polymers containing urethane groups." Source: http://www.pcimag.com/CDA/ArticleInf...,71242,00.html If you do a google on Isocyanate you'll find a ton of information on this. While I don't have any personal experience or problems from having sprayed poly (which I haven't done a lot of - I'm just an amateur woodworker), there appears to be a pretty good amount of stuff out on the internet indicating many people have a lot of serious reactions on exposure to isocyanate. I for one, don't need to find this out personally! I've gone water based just because I'm spraying in my basement shop and fumes are always a killer in the house, but this kind of clinches it for me.

Thanx for all the advice. It's kinda gotten moved on a side burner
for just a brief time since a couple of things have come up that are more "urgent". But, I've now got some stuff to muse on. Just to mention, I don't use poly a lot myself any more, but for kitchen cabinets I do think it's appropriate (though that Crystal Lac stuff sounds interesting). The accuspray unit is where I'm leaning - mainly because the cleanup is quick. Thanx again. Renata |
