Kremlin 15:1 for WB vs my Greco 9.5 HVLP

12/18/21

Hey guys and gals.

I have typically only used solvent based paints, but I have a job coming up where I�m painting 5 interior doors, with jambs, 5 bi fold doors, all the door casings and all new base throughout the entire house.

I currently have a Greco 9.5 HVLP siphon gun for WB paints

This job will entail me to spray WB ilva paint and MLC WB primer.

I already have two Kremlin, one for solvents paint and one for solvent clears.

I�m ok with buying another 15:1 Kremlin, but to only use for WB paints. Here in Chicagoland, we aren�t restricted to use WB, so I don�t want to spray clear WB

Do any of you use a 15:1 Kremlin for WB and have you sprayed ilva WB with iit?

Considering how heavy the 9.5 Greco cup is on my wrist and the amount of product I need to paint, will I have a nicer finished look using a Kremlin over the Greco HVLP? It looks nice, but not as nice as my solvent pigmented finishes do with my Kremlin.

Putting the investment part aside, I�m much more concerned about the quality of my finish than the cost of a new AAA to dedicate to WB.

If I do take the plunge, would you recommend a different tip than the one that comes with it?

You should be able to spray WB through your Kremlin using an appropriate denat alcohol pre-wash to avoid allowing your WB paint to come in contact with lacquer thinner/harsh solvents in your pump. Flush out all the "wash thinner" with alcohol, then flush with water.

I've done this a number of times on my 14:1 CAT pumps including spraying SW Duration exterior paint.

I'm not familiar with Ilva paint, If it's the thicker "wall paint" that's normally rolled on or sprayed with an electric pump, you're going to need to cut it with water and use a fire-hose sized spray tip, and even at that you'll need to experiment.

If you're only spraying 5 doors and such, I wouldn't go buy a dedicated 15:1 for spraying WB. Contact your Kremlin rep and ask their advice on tip size, and ask their opinion on doing alchol/water changeovers in your current pumps.

If you were spraying 500 doors, then yes, buy another pump. And if this is a thick wall-paint type, buy an electric pump.

Matt,

Ty for the suggestions. I has this discussion with my finishes rep and it wss not advisable to do the changeover. Being a single guy with no kids, I have the means to buy a dedicated pump, so I�m not concerned about the cost.

I�m more concerned about the weight on my wrist of using my Greco 9.5.

It�s not just 5 int doors, it�s 5 or so bi folds, several hundred feet of bsse, all the casing as well.

I just went by to know if the end result lock is going to look anywhere near as good as what I get for my solvent-based Finishes. Ilva and Melisi are sister companies and their WB paints are much more durable than SW,etc

If you have the money, go out and buy an electric airless pump like mentioned, if you have no intention of doing a lot of water base you can buy a smaller entry level or mid level machine.

In my opinion a 15:1 aaa pump is a little small for spraying most of the thicker water base coatings. It can be done, but it is like hauling all your cabinets and doors to the job site in the back of your car. Not very efficient.

I'll give you my opinion

If this is a job that comes around once in a while then I would just use that Graco sprayer that you have if the coating you are using is thin enough
I've had my share with turbine sprayers and never liked them
For one,I hate that heavy big cup at the bottom
Second,too slow!and blows too much hot air
If you are interested in getting an additional pump just for WB I guess a Kremlin would be fine
I just added an Graco Merkur 15-1 pump to spray WB like BM Advance when needed
It does a good job
I keep my CAT pump for solvent finish
I don't like converting my pump from solvent to WB
I'm always worrying about contamination so I don't do it
Whatever you decide,good luck with it!

FORUM GUIDELINES: Please review the guidelines below before posting at WOODWEB's Interactive Message Boards (return to top)

WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.

Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.

A valid email return address must be included with each message.

Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.

Subject lines may be edited for length and clarity.

"Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.

Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.

Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.

Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.

Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.

Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.

Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.

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).

The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards. Participants should undertake the use of machinery, materials and methods discussed at WOODWEB's Message Boards after considerate evaluation, and at their own risk.
