refinishing cabinet doors

12/20/15

Hi all,

While I was in school I had a part time job at a cabinet shop and I did a lot of finishing work, mostly raw doors but we did some refinishing and most of the refinishing involved starting with stained doors and painting them white.

I would like to refinish my own doors but I don't own a sprayer (we used a kremlin 1014 pump at my previous job). Is there anywhere that I could rent a sprayer or purchase one for cheap? I would probably go with a conversion varnish top coat and primer because the cabinets are factory so I'm pretty sure they used cv but I could test one before spraying all of them.

Thanks and Merry Christmas!

Doubt that you could rent a gravity gun, you would need a compressor too! Also, if you are spraying CV do you have a safe place to apply the finish? Need more info from you before 'good' advice is given.

Try ebay for a cheap(used) gravity gun with 1.2 or 1.4 needle/nozzle combo.

You could go with a turbine model.....but that's at least several hundred dollars and sound like vacuum cleaners.

A compressor I can probably rent. We used a sata rp gravity gun for spray stains and I assume that you are suggesting something similar but with a larger tip?

As for a safe area, I was considering setting up a spray stand in front of a window with a fan blowing outside, then spraying in a hurry and getting the hell out of there.

We used an automotive booth at my previous job. What are the potential dangers of cv?

I have a fine finish tip for my airless pump that I would feel comfortable using to spray doors (in a pinch). Airless pumps are readily available at any rental facility.

Any of the cheap gravity feed HVLP guns will do a very good job. You may not believe it, but the Harbor Freight 1.4 tip purple gun, which is sold on sale for about $10, sprays low viscosity finishes beautifully. It won't stand up to production use, but for a kitchen or ten worth of cabinets it will work fine.

Rather than risk an explosion with solvent based products, why not use a waterborne one? GF and Target both make pigmented topcoats that are KCMA rated. They come in white, and can be tinted any color you want. You would need at least a 1.8 mm tip gun for those, however, maybe even a 2.0. ML Campbell's Agualente waterborne pigmented lacquer is another product to consider.

Mark,

your post scares me......spraying CV- through a window with a fan. Is it possible for you can use the Cabinet shop that you use to work for on off hours.....

No, not possible. Again, what are the potential dangers involved? Keep in mind that I am talking about a very small condo kitchen. Maybe 15 or 20 doors.

Keep in mind Mark,it only takes a smidgen of a spark to cause a gigantically large humongous boom.

There are plenty of good water borne finishes these days to risk disaster using a solvent based one improperly.

Be sure to take the screen off the window.
Keep the fan on low, or medium, but have cardboard placed next to the fan to insure positive ventilation.

IMO spraying small jobs with out an explosion proof fan is not that dangerous. Keep in mind what causes sparks is the turning on or off of the fan and/or lights. As long as you turn on your fan and lights before starting to spray and do not turn them off until the area is clear you will be okay.

You are likely right 99% of the time Robert, until that one time when someone else comes into the room smoking a cigarette, or the electricity flickers, or someone turns on/off a switch nearby. Accidents really do happen. Why risk disaster when safe alternative products exist?

Robert,
I am only mentioning this for safety reasons. The difference between a regular fan and an explosion proof fan is that the explosion proof fan motor is sealed. Have you ever looked in a power tool when it was running and seen sparks produced on the inside? A fan motor is the same.
Mark,
Where are you located? The reason I am asking is it is against environmental laws in my location to spray a lot of solvent based finishes on a site, they are only allowed to be sprayed in a booth. As for your safety question, there is the explosion and fire concern and then there is the health concerns of breathing in the overspray and the off gassing while curing.
My advice for onsite finishing would be a water based product like Sayerlack and apply it with an airless pump, these pumps can be rented at Home Depot or a rental shop.
Good luck

JSO,
Electric power tool has brush's and it is those brush's that create the spark from constant contact with the spinning winding's, I believe that most if not all window type fans are brushless. My post was meant for people who spray small projects once or twice a month and can not justify or afford to spend $1000 on a explosion proof fan. Is there a risk, yes but it is extremely low.

As far as health concerns, obviously you have to wear approved respirators for any spray finishing whether it is water borne or solvent based and keep it on until the area is cleared.

IMO Spraying a water borne product like sayerlack with a airless pump is not the same quality finish as conversion varnish.

Robert,
I would agree with you on the quality of the product, I just thought it was a decent product, that was a lot safer for the original poster.
I don't think it will be that long and there won't be any solvent based finishes with the way the environment is going. It will be interesting to see how the quality will compare?
Have a great day!

    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).
