Orange Peel

I started spraying pre-cat lacquer last fall when the temperatures here in St. Louis were cool. I thinned my lacquer with 25% lacquer thinner and achieved good results. Now that the temperatures are higher I experienced some orange peel. I have never used a retarder but it looks like I will now have to do so. My question is two-fold: 1. How do I mix the retarder and how can I get rid of the orange peel? By the time I obtain some retarder the initial coat will be approximately 24 hours old. Will the application of more lacquer with a retarder in it sufficiently melt the underlying layer to level out the orange peel and if not what can I do to eliminate it. I am spraying 2 large refrigerator panels.

What are you spraying with you may not want to thin so much if the thinner is a hot one it maybe drying to fast try a slower thinner ask you supply you probably need to sand out the orange peel .

Another coat will probably not level the current orange peel. Block sand with 320 grit. You can get different drying rates of lacquer thinner. Go to an auto paint supplier if necessary. Better look at nozzle size and pressures for the viscosity you are spraying.

Orange peel means that there is insufficient material coming from the gun. Check to see that you are putting a sufficient wet coat down and add retarder at 10% to help it level out.

in spraying additional coats, be sure you do not exceed recommended dry mil thickness or the lacquer can crack. That is only more good reason to thin the lacquer even more than 25%. I wouldn't be afraid to go to 50% since you have established the film thickness you need and now you just need an additional coat that will level out better and establish the sheen you want.

I would scuff sand to assure good adhesion and to help level the orange peel. If there is a slower thinner available from the manufacturer I would get some and mix a fresh batch. Avoid standard retarder (butyl cellusolve)only as last resort. It can be hard to dial in how much and too much can affect the cure and sheen.

Manufacturers are moving to high percent of acetone in their lacquer thinner blends in order to stay in compliance with voc regs. Acetone is an extremely fast solvent and thus works against good leveling. Its getting very hard to find a lacquer thinner that is not heavy in acetone, but they are around.

I quit using lacquer thinner years ago as
a thinner only as a cleaner for my guns.
Most all the lacquer thinner now is
reconstituted junk.
I now use urethane reducer to thin my lacquer with, as suggested to me by a
chemical expert who knows his stuff.
It has worked much better.
It can be had at any car paint supplies store. And comes in various dry speeds.

Thanks to all that responded. I discovered the problem was too light of a coat; I was spraying a 1 or 2 mil wet coat. When I increased it to a 4 or 5 mill wet coat and eliminated the thinner things worked out well. Thanks to all that contributed.

    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.
