Pressure pot questions/suggestions

Bill Richardson  Member


I need to add a pressure pot and gun to my arsenal. After reading all I could find on this forum, I'm still lost.

There seems to be a fairly wide range of pricing for 2qt pressure pots. Are there any real advantages to higher priced units?

What would be a good mid-range setup (approx. $300-$500)? This setup will be for higher viscosity undercoaters and sealers. All top coats are applied with a Kremlin AAA.

First a couple of questions; what primer(s) will using? How much will you be spraying at any one time? Will you be spraying inside of boxes?
2 quart pots aren't the best choice highly viscous material, the screw on lids can leak air making it hard to reach the pressure needed to push your primer...the exceptions being, the binks sg2 and the cat bandit. Both of these have clamp down lids...but they don't come cheap, $300.00 on eBay. If you're spraying more than a gallon at a time get a 2 gallon pot. If you're spraying wb; teflon coated, aluminum or ss is the way to go.if you're spraying the inside of boxes get 15' of fluid & air line. If not and you won't be spraying much consider a stainlwas steel pressure quart cup.

have you tried spraying through your kremlin. you might just need a bigger tip.3-400 PSI from kremlin vs.10 PSI from a pressure pot.

Your going to use a heck of a lot less product spraying primers/undercoaters through your AAA... not to mention cleaning solvent to clean up a dang pressure pot all the time... I do not miss those days.....With the right tip/orfice size and the correct viscosity primer you should be laying it down like glass!!!!! I personally use Kemvar primers from Sherwin Williams and we have them pre-reduce it for us in batches of 100 gallons... it's always in a five and pre-reduced.... We catalyze it, agitate it and lay it on.... 5-6 mill wet pass... flash for a few minutes and hit it two more times.... that's three 5-6 mill wet passes...This gives the pieces exceptional fill... we let it sit about 30 minutes and force dry in a big curing oven at 115F for thirty minutes and sand it back hard.... ready for topcoat!

Sorry for the delay in responding.....

For tinted coatings we're not high volume. Some cabinetry but generally stand alone furniture. In the past we've shot pigmented pre-cat lacquer but are moving to Valspar vinyl undercoater tinted to spec and top coated with Valspar CV.

My biggest concern about using the Kremlin is mixing pigmented and clear materials. Getting the system completely flushed of any pigment worries me, hence the thought of adding a small pressure pot.

We are a very large volume shop 20+ million in sales a year and my booth finisher have a few pumps per booth.... we change back and forth between pigment and clear all the time.... it's just a matter of keeping your equipment clean... if the pump stays clean and you wipe the stem down and flush with two different buckets... one just a semi clean solvent and then a final flush with clean solvent and pull the screen on the gun there is nothing to worry with.... Heck I have one kremlin 10:14 at home I've used off and on around the house for ten years that one minute i'll shoot black primer and ten minutes later I'm running clear... no biggie if you learn to keep one clean... still beats running gallons of acetone through a pressure pot and scrubbing the lid of it to clean it real good...

I agree with just using the AAA. I use C.A. Technologies Bobcat's, 3 of them. One for primer, one for paint , one for clear...

Yes more of an investment , but never any thought of white specks in the clear is well worth the money.

For small jobs like a piece of furniture I would use an HVLP gun with a pressure cup. You can spray a pretty good sized cabinet or piece of furniture with a quart cup and clean up is much faster not having to clean out lines. I just bought a gun with a 3M H/O PPS cup which allows you to spray at an angle, including upside down, and clean up is even easier.

We use a Kremlin 10:14 pump but have not had much luck getting it to clean up properly after using pigmented primer or top coats. We use both MLC and Chemcraft products. We always end up having to take the bottom pump assembly apart to clean the ball and cage. If we don't do this the pump creeps and will not stay in the down position. Because of this issue we use a pressure pot for pigmented products.

Shane could you share your cleaning procedure?

The only thing I use my pot for is to spray clears. I sprayed a pigment one time and thought I cleaned it good but every now and then would get specs of pigment in my clears. Bought new hoses. I wouldn't fool with a 2qt, the screw on lids are a hassle.
If I were going to buy a new pot set up, I'd spend less on a pot and hoses and spend more on a good gun. That's just my 2 cents.
I spray all my pigments with gravity guns.

One other option that can be cost effective (especially when compared to a new AAA) is to buy a small used airless of your local craigslist. Graco 390 or 395, Titan 440 ect...
They are great at pushing viscous material and not bad with finish quality or overspray when using a fine-finish tip at just enough pressure to get a tail free fan.

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
