Titebond II, am I the only one with issues?
Hiya,
I've been using Titebond II pretty much exclusively for all my projects the past few years. I posted a while back that I had problems with the glue after finishing when it crept. I kind of put it in the back of my mind thinking that maybe temperature had been the culprit (I glued up pretty close to their lower limit). Well, today I wandered by one of my projects, a cherry bed built about 3 years ago and low and behold, I have glue creep. Now this thing was built in the summer and I took my sweet time with it (meaning I didn't glue up and start sanding within the first 12 hours....more like days between the glue up and futher working of it). What's going on here? Am I the only one with this issue? Could the glue be "spoiled" (ie. age wise)? I'm pretty ticked off as I noticed I have this problem on just about every other project around the house as well. Is there another glue that folks recommend (yellow or white preferably). Thanks for the rant! Cheers, cc |

Can you take photos? It would be very useful to see the exact
characteristics of what you are talking about. I can't say that I have ever had an issue with TBII, but I have not used it much. I use standard Titebond whenever I can. In the back of my mind I always think that it is best to use the most tried and true when you don't need the characteristics for which a specialty glue is intended. A very good example is the use of polyurethane glues. Hate that stuff. I only use it if I have to glue dissimilar materials to wood or some examples of waterproof applications. It is messy on the project and on your hands (if you don't use gloves). Now you are making me wonder if there is any concern about Titebond Extend. I am considering using that as my mainline glue because it would give me added working time. Should I stick to my rule? |

I'm using the term "Glue Creep" to describe what appears to be glue that
over time, has squeezed out between joints. Not sure it's the correct terminology. Basically what I get, and this is for edge glued stuff, is a slight ridge where the two boards are joined that wasn't there when I built it. I can't take photos of it as it's really too small to see but you can definitely feel it as you rub your fingers over the joint. My method of edge glue ups goes something like this. I joint my edges, set up the clamps with cauls as needed, apply the glue, clamp the boards, and let sit for anywhere from 12 hours to days. Afterwards, I scrape the dried glue off and give the panel or whatever a good sanding (or handplane sometimes) to the point where you cannot feel the joint with your fingers. I typically finish with a light coat of oil (linseed, watco, tried and true, etc...) and then shellac. After all the finishing, the joint is still as smooth as before. Months (or even years) later, I'm getting this ridge where the joint is. I had this happen once before on a box I made and the diagnosis from the group was I believe, "Glue Creep". I took a scraper to it and very gently removed it and sure enough it looked like dried glue. Thanks for any help/advice! Cheers, cc "Leon" wrote in message m... Define Glue Creep. |

Mmmm. Are you sure it isn't the wood creeping? By that I mean that if
two pieces from the exact same board were not glued together, a slightly different cut (say for example, one more plainsawn and the other more quartersawn) might produce an edge situation like you describe. |

Well, today I wandered by one of my projects, a cherry bed built about 3 years ago and low and behold, I have glue creep. It's sort of the accepted thing on instrument (guitar, etc...) making forums (like mimf.com) that Titebond II is not suitable for instruments because of glue creep. Hide glue (the ground stuff that you mix fresh yourself, not the pre-bottled stuff) and original Titebond are probably the most two most common glues used for building instruments. But when they talk about "glue creep" it usually means that the joint is moving, not that it's really squeezing the glue out of the joint. Jon |

Thanks for the rant! Any "white" glue will creep under sustained load. The solutions are to design your structure so that there is no shear load on the glue joints or to use a different type of glue (plastic resin or phenol-formaldehyde for example) that does not creep under sustained load.

Thanks for the rant! Cheers, cc I am beginning to wonder if it has something to do with clamp pressure. and the quality of the joining of the boards. From all accounts white and yellow glues do "creep". So if clamp excessive clamp pressure is used to ensure squeeze out the jointed edge is in compression ,some areas more than others .. When the clamps are released the compressive load is gone but in the joint "valleys" there will remain in fact a tension load which over time will be allieviated by glue "creep". I dont know the solution other than using hide glue where. most joints of this type were "rubbed" joints requiring no clamp pressure.....mjh . |

Some have described a problem when sanding prematurely after glue-up.
Gluing introduces moisture into the wood and sanding too soon after clamp removal removes wet wood from the joint and after the moisture departs the wood has "shrunk" leaving the glue line proud.

I haven't experienced the problem you are citing but one possible explanation is that the wood was not totally dry when you did the glue up. Over time the wood will shrink but the glued edge will shrink less due to the wood cells being soaked with glue. Basically the glue saturated cells will feel like a ridge. One way to check this is with a caliper if you are confident in the 'final' dimension of your boards. The 'ridge' would be virtually the same as your 'final' dimension and the base wood would be thinner. TWS |

PVA glue does not expand or contract with humidity changes. Wood does. Another thing that might cause the problem is not allowing enough time for the wood to acclimatize to the environment (where it will reside) before glue up. Check the piece when the humidity is high and see if the glue line is still proud of the wood. -- Jack Novak Buffalo, NY - USA (Remove "SPAM" from email address to reply) |

That's not the common definition I'm aware of...creep is the gradual shift of two pieces relative to each other under long term loading and is a potential problem w/ any non-hard glue. You're right that proud glue lines are not creep but the result of differential expansion from temperature or more commonly moisture... |

Basically what I get, and this is for edge glued stuff, is a slight ridge where the two boards are joined that wasn't there when I built it. One of the things I do (when I remember to do it) on edge gluing is to scratch a little groove about a 32nd in from each edge of each board. Then I keep the glue between the grooves. No squeezeout unless I use way too much glue :-). If what you're seeing is the result of wood movement, my method won't help. Except if it's the wood shrinking and the glue not shrinking. -- Homo sapiens is a goal, not a description |

Thanks folks for all the help. A few answers to some of the questions
popping up. 1. Wood being used is typically 5-7% moisture content. The wood is seasoned in my garage for a few weeks. Cut to rough dimension, sits another week or two, then I cut to final dimension. 2. Clamping pressure is pretty minimal meaning I don't crank the heck out of the clamps. 3. My joints are nice and even before glue up and after. In fact, some of them, with the grain orientation etc... you cannot even see. I've obviously misused the term "Glue Creep" as these are pieces that have no stresses on them in most cases. I suppose it's possible the moisture content might swell the thickness a bit but it just seems odd that none of the other furniture in the house seems to have this issue (not my construction). Using shellac as well, I wouldn't expect to see moisture changes at the joint although I may be wrong on that assessment. I suppose a more accurate description is "Proud Joints". I believe I'm jointing, gluing, clamping just like most folks so I guess my question is now becoming "Is this normal?". Cheers, cc |

5-7% is pretty low for equilibrium moisture...where are you located? If
it's not in a very arid climate, I'd expect that the final moisture is, in fact, higher and is a likely cause. Sounds like your working is ok other than I suppose it might be possible (although unlikely if you work anything like I do on fine work--not enough time for that ) you are sanding near the joint too soon after gluing and the excess moisture has swollen the joint somewhat so that when it subsequently dries the glue line does stand a little proud of the surface. Some moveement is not unheard of, for it to be extremely prevelant indicates to me there's some difference in moisture equilibrium between the working area and the finished pieces' environment. I notice the piece you mentioned was cherry and built in the summer...if your summers are humid and you now are looking at very dry, heated indoor air after a couple of years, I could see that... |

No humidifier hooked up. I do have to say however, that humidity does
tend to swing quite a bit. Usually it's dry (say 15% most of the summer) but rains come and jack that up for a week or so to say 30%. Winters are usually pretty dry. I am finishing all the sides of the pieces (obviously not the mortices/tenons). Just seems odd that the boards move on my projects but not the other furniture. cc |
