Titebond for veneering?

Don't have any experience with veneering, but I have done some bent laminations with urea formaldehyde glue in the vac bag. I have some smaller panels I wanted to veneer, like ~10"x16", 7"x48" and similar sizes in those dimensions. I'd prefer to not deal with the UF glues if possible, are there any issues using titebond I? Is balancing the panel a concern with the smaller dimensions, if so, can poplar be used to balance cherry and walnut? I'll be resawing the veneer at 1/8" thick. I've got plenty of 3/4" Baltic birch I was planning to use, if that's an issue I'll get a sheet of mdf.

Usually, the Titebond glues are avoided since they add so much water into the veneer, causing to absorb it and swell, even while under pressure. I have seen assemblies that look like a moonscape. 1/8" thick may not wrinkle but it can swell just as much as thinner veneer.

Unibond 800 from Veneer Systems is a good glue, as is UF resin. We also use urethane glue for veneering. Even epoxy.

You are doing the right thing by experimenting a bit. Balanced is always considered good, but probably not an issue with 5" x 5" squares at 3/4" thick.

This is one time that I will disagree with David. I use Titebond II for veneer regularly. I cold press in a vacuum flip top press and I get consistent excellent results. I spent a few years hot pressing with UF glue and would leave work with itchy red eyes and constricted throat. I swore I wouldn't use it again.
The key to success with PVA is to spread a thin layer of glue consistently on the substrate. I use a hopper roller. You can use a small foam paint roller to spread a barely opaque film. Clamp for 30 minutes to an hour.
In my experience panels warp because of poor handling after pressing. Leaving on face to dry faster than another will result in warped panels. Beware of heaters, strong sunlight etc. hitting one side only.

I second Tom's reply. I have pressed quite a bit of raw and paperbacked veneer with Titebond I, II and I Extend in a vacuum press with good results. I use a notched trowel spreader (Klebo) and follow up with a non-absorbent roller to get an even spread on quickly. I save the toxic UF resins for problematic veneers like burls and use epoxy for exterior work.

Balance is important. You may get good results with poplar backing cherry and walnut, but experiment before counting on it. Thicker veneers will accentuate any imbalance.

Baltic Birch has not been a very stable material in my experience, but some seem to like it. I use mdf for dry exposure, Medex for kitchens and baths, and Extira or marine ply for exterior work.

Thanks guys, very helpful feedback. I'm adding fixed panels that are inset into stainless frames and wanted to get a good color and grain match to the other solid wood components in the pieces so I'm cutting veneer from the same stock.

I've always considered 1/8" as too thick for veneer. I feel it still acts like solid wood at that thickness instead of like veneer. I resaw to 3/32" and then thickness sand to clean that up.

I have only tried PVA once for veneering, and the Ash Burl puckered mercilessly. However, by reading closely what you say about application thickness, I probably had too much.

I can see where it will work, and if it works well for you, great.

I have to have a sure thing, no fingers crossed, 'just about enough' or dice rolling.

I have glued 1/8" and thicker many times, but anything of any size (2"-3" x 4"-5") does not get PVA.

Only thing I can add is I usually prefer TB Cold Press which is designed for veneer work. Also I use one of the pink textured rollers made for contact cement to roll out the glue. I find it gives a nice consistent coverage.

good luck,
JeffD

I also have used TB 1 in a vacuum press and have had great results. I have also used the TB Coldpress and had horrible results. I experienced a significant amount of creep from flat glue-ups. Will never use that again. TB 1 & 2 are fine. For curved work, both TB 1 & 2 will work, but there will be more springback. The UF glues are better at controlling this.

Bad experiences with Titebond Cold Press adhesive. TB 2 is better. Slow and slippery, but leave in the press four hours to be certain. We do large tables (36" x 96"), and larger dries slower than small.

    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).
