this problem arrived at my shop the other day & this is the story as it was told to me from 3 of the parties ( minor differences in each story) of the 6 parties involved (seven now including me);
cabinets were made 1.5 years ago, birch euros with flat panel doors, end panels and drawers stained and finished with a Rudd deep red brown cherry colored stain and satin CV. the customer did not like all the varied grain showing through so the Rudd rep made up a highly colored shader in a red/brown using Rudd dyes. 2 shader coats were applied all but eliminating any visible wood grain (I don't know the thinner to finish ratios) then 2 more top coats of CV (I 'd bet at this point it's exceding the 5 mil limit and then some). After 2 weeks a sticky oily white haze appeared on all the surfaces that had been shaded, the backs that weren't touched still looked great. this was a year ago.After a month of the white haze and no answer as to what caused it (Rudd's reponse was something is precipating out of the finish) the cabinet maker sanded off all the finish and refinished using the same finish schedule that caused the problem (yes, that wasn't too smart but sometimes we get so busy we forget slow and steady is faster then full steam ahead) and of course 2 weeks later the white oily haze appeared again now close to a year later the owner wants to get it right and move on. the cabinet maker and the manufacturer are paying.
l have one of these doors in my shop and the formaldehyde out gassing from it can be smelled from 5' away and the furniture maker who recommended me says the whole house reeks of it (yes l told him that all the cab parts should be taken somewhere outside of the house. Plus the cabinet maker did finish one drawer that was misplaced in his shop with SW waterwhite CV and it has no oily white haze and looks perfect
So l have made a acceptable sample and my plan is to chemical strip, sand & finish...simple as that. of course l'll test first on the door l have.
now, if you're still with me; has anybody seen or heard of this before? or know what's going on?...thank you.
If it's over catalyzed, you can wash off the leached out catalyst with baking soda. Mix 1 part baking soda with 10 parts water and wash down the parts. Soak the rag and then squeeze out most of the mix. Don't over use the rag but keep getting new ones.
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.
Carefully review your message before clicking on the "Send Message" button - you will not be able to revise the message once it has been sent.

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.
