Spraying Conversion Varnish

1) What needle should I use, I'm using a Mohawk product?

2) Spray pattern - is it the same when spraying lacquer, going first in one direction and then going at 90 degrees? Do I need to be careful with overlap?

3) How sensitive is it to temperature and humidity? I'll be able to keep the temp at around 70 degrees, humidity I can't control.

Thanks as always.

Your 2nd question is hard to answer it screams I don't know the basics.
Get experience the best is to get a kitchen door spraying job, having a good hand is number one skill to learn.
Mohawk has lots of videos learn and watch the hand also Youtube but find experienced guys not want a be.
I've almost finished a high gloss video showing burled elm from a 1991 MG .
Also, there is no stupid question just spend a little time first

3rd question high heat is an enemy when spraying can bubble on certain lacquers had it happen on conversion varnish

Don't know about Mohawk. But ML Campbell always states 25�C (77�F) which of course is very warm but heat will generally not cause solvent pop. Air currents over the wet substrate are usually the culprit for solvent pop bubbles.

So for your first question,we need to know more
What exactly are you using and what kind of spray equipment you're using

For the second question
Start at the edge (center of fan)
Then go back with a 50% overlap and so on

For your third question
Ideally most finish is based on 77`/ 50% humidity
Don't spray under 65`
If it gets too warm,start to use flow enhancer to slow down the drying

Here is the video of high gloss clear it's good to understand the process and can change the look of a furniture guy.
What I see a lot in videos is guys flicking their wrist not keeping the arm straight and understanding why that is a huge difference .
I had someone come in the shop wanting a job as a finisher that never sprayed vertical but wanted to learn at my shop at 22dollars an hr. only because where he's working there dumbing down the work making everything flat.
I was lucky enough to work a few years in aircraft executive jets doing high gloss finishes that were polished.I had a car finisher that worked there helped me a lot to learn proper spray techniques were not born with the gun in our hand.
Also, that experience taught me to be so careful with my health these chemicals are no joke

Use a 1.4-1.6 tip and I start thinning the CV at 10%. On humid days I add C1161 retarder. Start it at 1-2% and no more than 5%.

No there was another flag he told me he didn't like the wear and tear on his vehicle I was only 10 mins away from home and where he worked was an hr. away. Plus my shop isn't geared for a full-time finisher.
I need someone that can install, prepare wood, assemble cabinets and learn the CNC. Still waiting for someone that can fit, hard because the shops in the area think it's it better to keep the workers one dimensional [example head installer, head sander, head assembler ] I think it's so boring for the workers. I don't think you can be a cabinetmaker unless you can spray, install and design.
I know the only way is to have someone that is young, green and to train.
But were in a time of great exchange of ideas thanks to the computer I learned how to run the CNC on Shopbot form 13 years ago the sign guys opened my eyes.

The larger kitchen cabinet factories here in MN are paying at least $20.00 an hour to start and $22.00 and more if 2nd or 3rd shift. When I see a person that all they do is blow off sawdust on parts before finishing and are paid that amount I'm just flabbergasted. You can still find 1 bedroom rentals for around $500 per month that also include heat here. It's just crazy.....

That larger kitchen cabinet factories also has a couple of designer who talk about craftmanship.
I was hoping with CNC being affordable there would be more guys doing real custom work so you don't have an old man yelling at the sky.
I have a new video out on cabinet material basic construction hoping someone like Dave does a video
The sad thing is when someone walks out of those big factories in 10 years they have zero skills the only place they end up is at the big box stores selling kitchens.

I'm not sure we're comparing apples to apples here. Mr Dunphy is located in Canada so I'm thinking rates of pay may not be equal. That said, you will definitely not find an experienced finisher in the mid-Atlantic states for $20-22 hr. Of course, you're not going to find any apts. at $500 month either.

I'm in agreement with Chris Tayler in his points; also taking into account that he's speaking from experience. Have a great weekend!

That wasn't the point the 22 an hr. The skill level is dropping in cabinet making. My son makes almost 6 figures I can't afford him he won't be running the shop and his girlfriend is looking at 6 figures teaching at the university. I'm well aware of the wages in today's world
You look on Youtube is full of people who never spent one minute in a cabinet shop giving out cabinet-making advice. The experienced shop is going the way of the dinosaurs for lots of reasons mainly so expensive to open a shop even a decent 4 man. I grew up in Toronto so I've seen crushing rents firsthand.
So there is a big hole for mini-factory shops all advice is given by salesman selling equipment. Hence all you need is min wage workers so the cycle of skilled workers is accelerated.
Sorry if I hijack this thread just wanted to make a point
Also, I have a new video on the subject

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.

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.
