glue creep

7/7/14

About six months ago I made a hardwood lamp incorporating white and red oak. The lamp was made from a number of component parts and required a fair amount of gluing and clamping. Now, I see that a couple of the glue joints have some glue creep. If you look down the seam of these 90 degree joints you can see clusters of very small white dots which are dried glue. I used Titebond. I've read that resin glue like Unibond800 doesn't creep. But it's expensive. Is there some other way to prevent glue creep?

Titebond 1 will not creep. It drys harder than 2.

Regular Titebond (red cap.....often referred to as Titebond 1) dries very hard. To see this look at the dried glue around the glue bottle spout. It will be crystalline in nature and will shatter if pinched with a pliers.

Titebod II dries very elastic. To see this again go to the bop of the glue bottle. When you grab the excess glue and pull on it with a pliers you find it stretches.

We're aren't talking a huge difference in creep in a glue joint with one or the other. Many shops won't use yellow glue at all due to potential creep. We use regular Titebond on interior lamination projects where creep would be an issue and have never had any call backs. There are times though where we switch to epoxy to be safe. I prefer not to use the powdered formaldehyde glues.

Thanks B.H.! I'll definitely go back to using Titebond original which I used to use.

I have a commission for some bent lamination work and in my reserch I came across the idea of adding corn starch to PVA glue at 8% by volume to help eliminate spring back.
I have to credit Fine woodworking for the tip.
I did a couple of test pieces one with 2 layers of 3 layer bendy ply, the face and backing veneers of flat sawn maple (no starch).
the other one with 2 layers of 3 mm mdf and rift sawn red oak veneers with starch added to the glue (white pva with a long open time)
The first one had spring back and the second one almost non at all, maybe a mil.
I know its not conclusive as there are different materials involved in each but I'll be damned if it doesn't work.
Perhaps this could help you as well?

We've had this thread a few times over the last 10 years.

TiteBond 1 negligible creep
TiteBond 2 some creep
TiteBond 3 lots of creep
TiteBond White or Elmer's white so much creep you can't believe it.

I've tried to sand back TB2 several times and it eventually will telegraph thru paint later when its its installed in a house. I've never had an issue with TB1.

Please don't start arguing about the proper woodworking term for glue movement. Creep, telegraphing or whatever word you like will do fine. Some people get cranky when improperly using the word creep(its an engineering term)...not me.

  • 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.

  • 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.
