What's the deal with this? My paint guy says it's the only way to shoot this heavy duty industrial paint and have it come out even. Is that true? I can borrow one. Any pointers? Thanx
No idea about them in commercial use hwoever I have a couple of them I use at home. And while it appears that previous discussions on this topic places me in the clear minority on this subject I still feel these are the MOST kick *** setups for the weekend warrior ever invented. Sure most PRO's will advocate the use of the latest and greatest HVLP setups - I will go out on a limb and say that a home guy will NEVER ever notice the difference between a pressure pot and a HVLP gun. Are the HVLP's better?? COuldn't tell you - but I can say that MY skills have yet to exceed my DeVilbiss MBC pressure pot setup. Additional benefits include that as a weekend warrior I just don't use the particular muscles enough to allow me to hold a "conventinal" type gun holding a quart of paint over the hood of my car dead steady for two, three, four or more coats of paint. AS the night goes on I get fatigued and less steady as I am trying to shoot the finish coats. Not a problem for a PRO who may do it daily, but definitely a problem for me. NOT so with my pressure pot as all I hold is the gun itself (remote pot). Next problem is price - I bought my MBC for 10 or 15 bucks at a swap meet - and the same for the pot. I tried using a cheappy HVLP - garbage. Not saying they all are garbae (I'm sure for the money soem are entirely kick ***) - but dollar for dollar I can't beat the MBC with a pressure pot. And man - over spray - freakin nothing! Of course you do waste some paint cleaning up so I suppose that is a bit of a downer - but again as a weekend warrior - that's never amounted to a hill of beans for me. Personally I think alot of today sproducts are scams - clever snake oil engineering to make us think that we NEED the latest and greatest. Long winded point going off topic AND into probably alot of what you DON'T want to know - (sorry) I 'll sum it up this way - TRY ONE!!!! They're awesome!!!! WOuldn't trade mine for love nor money! ...ok well I wouldn't trade it for money
Cool, thanx man. Does it shoot as clean as a hvlp? The guy who's shooting it for me is scared there's gonna be major fumes or something and turn his booth charcoal gray! (leading to his inevitable demise at the hands of his boss!) Any truth to that?
I have a Binks Mach 1 HVLP hooked to a 2 gallon Binks pressure pot with 25' of hose.....it is awesome for shooting a complete car.....mix all your paint, set the pot at front of car, and I can 'walk' the whole car....every coat is exact as I don't mix more paint between coats....plus the manueverabilty of the gun is much nicer than a quart gun, siphon or gravity. It has drawbacks, cleaning, etc....not well suited for smaller jobs, even though a pressure pot will only leave @ a dime sized spot of paint left in pot when it runs out.
Does it have it's own dedicated gun or do you use a separate gun? Sounds dumb I know, but I've never even seen heard of one till now!
Hey, Pressure pots are, and always have been great for shooting alot of material ,reduced/thinned to the same mixture, at one time. The down side is if you deside you need to change the reduction or add/subtract hardner, you have 1,2 or more gallons of material that you have already mixed. The gun used with a pressure pot has both a fan and a fluid adjust- ment, just as a conventional gun, to use for spray width and the amount of material applied each p*** i.e. pattern. S****ey Devils C.C.
Pressure pots are a great tool for painting but I find I reach for mine on large jobs or if I am painting upside down. Once you get used to them they work great for normal paint jobs as well. I used to do custom paint projects for GM on big trucks and if I did not use a pressure pot I would still be painting them. We also used them for fleet projects and they are great when you know how to adjust them. I just recently used my two quart pot to paint the ch***is and underside of a car. They work great. The key though is learning how to adjust your particular gun. Both siphon feed and gravity feed guns have the air travel through the gun itself and mixes with the paint before it reaches the fluid tip. A pressure pot pushes the paint by pressurizing the pot and the paint in it. Try setting your pot pressure on the lower end like 5 lbs and see how it sprays and then try a bit more. Try some test panels. If you get up over 10lbs pot pressure you might get in trouble with too much material and runs or heavy texture. They make HVLP guns now in the pressure pot style and the major difference between old pressure pots is that they are more efficient. Tell your friend not to worry about the booth as they should not create any problems for his booth. Good luck-Jim
I've got pressure pots as small as 1 quart - so no problem there. I agree with Jim, no problem for the booth. Mine when set right has almost zero overspray. About 100 times less than my old siphon feed gun.
that's awesome guys thanx so much for the heads up! I'll start at 5lbs like you said and go from there. I'll let you know what happens. If you have any pointers as per mixing, shooting distance, whatever please let me know. Thanx again
I mix my paint the same whether I am using a pressure pot or not. It is best to follow the spec sheet for the proper mix. As to shooting distance that often depends on the air cap you are using and speed of your p*** and how much material you want to lay down on that particular p***. The guys are right that they can be a more difficult gun to clean but there are a couple things you can do to make it easier. I used to have a 3 gallon pot with a 30 foot paint supply line and a 10 gallon pot with a 60 foot paint supply line and I used liners in the pot and it saved me a ton of cleanup. When you are done painting, take and place a rag tightly against your air cap and pull the trigger. It will back up the paint in your line back into the cup or pot and you will hear a burp when it is finished emptying the paint out of the line. Then remove your liner and add a good amount of thinner and clean your supply line. I run another good p*** of thinner after cleaning it all up and you should be good to go next time. When I did fleet work my guys would often fly out of the shop on Friday and come Monday I would have to install new supply lines so it is important to clean the supply line pretty thoroughly. Good luck-Jim
my buddy says he only has the new pot to lend me, no lines or gun. What do I use, a regular gun with a regular air hose to deliver the atomized paint to the gun from the pot? Painting booth booked for tomorrow, starting to freak out a little.
My DeVilbiss MBC is "special" for use with a pressure pot. Nothing truely special it's just set up from teh factory with the right combinatin of Air Cap, Fluid Tip and Needle sizes. So YES you need a "Pressure Feed Combination" set up on the gun. The hoses - one suplly just air so a "regular" hose is all that is required. The other hose moves the paint (maybe you could get away with a regular hose - I dunno) but your supposed to run the "right" hose. They probably sell various ones - the one I got has a internal liner - makes for easy cleanup. My pressur epot was missing the "paint hose" so I went up to the local industrial/commercial hose place and they crimped one up for me while I waited - cost maybe 20-25 bucks - but that was like 10 -15 years ago. So NO on both counts. Call your buddys - someone may have what you need already.
I found out why the paint shop recomends using a pressure pot to shoot this paint: it seems to keep the flattening agent continuously stirring, (which is a powder heavier than the liquid paint and settles to the bottom) thus avoiding the common problem of flat paint jobs that tend to have uneven (glossier) spots or streaks. Makes sense? I guess it does to me. Problem is nobody aroud here (Montreal)seems to have a pressure pot to lend or rent to me including tool rental places. Do you think I can get the same effect if I put something like a bolt in the canister of an HVLP and shake it around between painting panels? This probably sounds stupid, I just don't have the resources to experiment anymore.
Hey, I don't know what "industrial /commerical" flat finish you're going to have your buddy shoot, but you can shoot this, just fine with a siphon gun. Most of the problem jobs I've seen that involved a finish with flattner in them, resulted from poor triggering of the gun or improper choice of reducer for the job at hand. Try wet p***es after the tack coat, and slosh the cup, as you would a rattle can every few p***es. Ya gotta keep a wet edge on most of these flat finishes , as you're shootin''um, and use your best trigger- ing, or they will not all flow out well. S****ey Devils C.C.
Hey, A "wet edge" would be a full wet coat. A complete wet p*** with no dry spray above or below the p*** just sprayed. A fifty percent over- lap to the p*** just laied down. This can be tough to do with a cheap HVLP gun, as most don't get enough pressure without being hot rod- ded/modified to work well. A cheap or old siphon cup gun could well be your best route if this job is a one note somba. My old Binks #7 with a 36SD cap and need le has shot everything form dirt clods to dimond dust and never done me wrong. Siphon guns are pigs as far as material consumtion goes, but for heavy,cheap material, like flat/matt, they're tough to beat. S****ey Devils C.C.
I know this is an older post but here is a an article covering pressure vs suction feed spray guns and below is a video highlighting the siphon, gravity, and pressure feed guns for review should help give visual backing to which may be right for your needs.
