sand between coats

What are folks using these days for
abrasives between coats.
I am spraying cabinet doors with the target WB em6000. Typically after 2 coats of sealer I do 320 and sometimes 400 on my 6" orbital & sometimes. I am currently using mirka & sometimes the abranet mesh.

I really like the Mirka mesh, it does great.
I also sand my sealer coats with 320 grit.

put a soft backer pad on your orbital and it will take you to the next level. Your paper will last longer and you will get a more thorough sanding quicker without cutting through. At that point the brand of paper you use will matter less, though you still get what you pay for. you just have to be very careful at the edges. In my opinion 1/4 or 1/3 sheet sanders work better on doors due to the square corners

I can't even imagine using a random or any power sander on cabinet doors. I like to leave some material on. It's hand sand only for me. 400gt Norton and purple 3M synthetic steel wool.

Bart you need to see a demonstration on how this can be done. its way faster, your paper lasts longer, and you have a pair of hands left at the end of the day

We sand as Jonathan says. 1/4 sheet sander, pad depends on what we are sanding. 320-400 but nearly always 320.

There are still areas that are hit by hand but its absolutely the truth that its miles and miles faster and its more consistent. I remember sanding 100+ door jobs all by hand, both sides, twice. What a nightmare. It's ripping fast with orbital.

With 320 and moving fast due to the efficiency of machine sanding you in no way cut all the finish off. If your worried about it run your first coat a hair heavy. It's never been an issue for us.

Large panels are night and day in speed and quality. Vacuum pickup on the sander us a major bonus as well when it comes to wipe/blow down.

Mark, When you say move fast that brings up a few more questions. When sanding raw wood i go pretty slow & overlap. But when i was in a pro finishing shop the other i saw them go really fast presumably between
coats. i guess that's what you mean.

Mike, check into the Surf Prep 3 x 4 foam sanding system. Excellent for sanding between coats and used with a vacumn dust extraction, we use our Festool vacs. Call them and get a demo, it will save alot of time and give excellent results. We have not looked back after putting this into use. We also use our 6" festool with their products to do large areas.

    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.
  • Comments, questions, or criticisms regarding Forum policies should be directed to WOODWEB's Systems Administrator

    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. WOODWEB reserves the right to delete any messages it deems inappropriate. (return to top)
