How effective are chemical strippers on conversion varnish?
How about glazing?
I may have a refinish job that I would like to use CV but the doors and drawer faces are mitered rail and stile with a small rop molding and it is glazed
The client may want new doors but I do need to give him a quote on refinishing existing doors and drawers
Commercial grade removers will take it off with no problem. The problem is that many Kitchen cabinet doors do not survive stripping very well. They tend to fall apart if they are cheaper doors.
We have found once you buy the remover, labor to strip them, resand wood to prep for finishing you are not to far away from buying new doors that just need a quick sand and are ready to finish. Wood species and shop hourly rate does play a big deciding role in this.
Don't forget the cost of a high end air supplied respirator if you are going to use methylene chloride industrial stripper in that bid. It's incredibly unhealthy stuff! Cheaper to buy new doors compared to the labor it will take to clean out that rope molding.
Methylene chloride strippers are no longer available, unless you can find some old inventory. NMP based removers are, for all practical purposes, unavailable.
There are some removers (available at most Lowes stores) that are based on an NMP substitute) that take a lot longer to work, but are effective. There's Smart Strip and Smart Strip Pro that are di-basic acid based that work well but take many hours. These are applied in a thick coat and paper is wrapped on them.
Don't know if ether are effective on conversion varnish. Both rinse off with water. Rope molding shouldn't be too much of a problem if they're at all effective.
I live in the very blue and silly state of CT. Dad's is still available, no problem. It's methylene chloride and no lye. No lye means it won't darken the wood.
There is a myth as to just how dangerous methylene chloride is for you. No chemicals are good, but the science just is NOT there regarding the dangers of methylene chloride. The history of this chemical being over-regulated is that the giant furniture industry lobied for it to be over-regulated, impinging on many restoration shops to carry on with cost effective refinishing projects vs a potential customer deciding instead to buy new furniture. That's the history. Furniture industry lobbyists and the wined & dined Congress.
The toluene in Dads is worse for you than the methylene chloride.
1. Brush on the mc stripper.
3. Scrape off without gouging the wood.
4. Grab handfuls of wood carvings that come off the plane (wear thick rubber gloves) and use these shavings instead of rags.
5. The wood shavings are especially effective for getting the sludge out of the carvings and shapes of profiled surfaces and moldings.
6. Water rinse with a pressure washer set on low pressure so that you don't etch the wood. The water has to bounce off the wood, not soak into it. It will take the stripper with it.
7. Wipe down with half denatured alcohol/half water.
8. Wipe down with lacquer thinner.
9. Lightly sand and build your new finish schedule.

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.

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.
