Great Video. I agreed with everything you said about glues. Spot on, and well presented! I am a Contractor, and was a shipwright for many years. I did a lot of woodwork and veneering on the yachts I built, and I have used epoxy, formaldehyde glue, wood glue and contact cement for veneer. Contact cement was great because we could do a 12 foot sheet of rosewood right in place on the boat, but you weren't kidding about it not being a good option for veneer. Several of our warranty work projects had failed veneer. It was always in an area that was in the sun near a window. the veneer blistered had curled up. The dash wash done with a vacuum and epoxy with woven fiberglass on the underside to keep the dash from warping, since it being in full sun all day everyday in places like the tropics, and we never had any failures with epoxy.

@VacuumPressingSystemsInc
@VacuumPressingSystemsInc 3 жыл бұрын
Like I said, I don't use contact cement for any veneer work unless it's plastic laminate backed. The problem with paper backed is it's still flexible enough to bubble under contact cement or be somewhat wavy. When the veneer is laminate backed these issues do not arise due to the rigidity of the backing material and using contact cement works fine, but not with paper backed veneers. Sometimes using contact cement will come out reasonably OK but it's a bit of a crap shoot. I often say, I sell more vacuum presses due to contact cement failure than any other single reason. Your taking your chances with this type of glue.

I've used a catalyst glue that I mixed from powder and Titebond 3 when wood veneering in a vaccum bag. The Titebond 3 worked the best. The catalyst didn't adhere as well as the Titebond 3 and the catalyst glue had to stay under vaccum longer. I will only use Titebond 3 from now on for porous wood surfaces.
@williamyoung3070
@williamyoung3070 Жыл бұрын
The problem is that Titebond 3 cures to a notoriously soft glue line. Titebond 2 and 3 both cure to a less rigid glue line than regular Titebond. You need a harder glue line than Titebond 2 or 3 will provide. The way to get a hard glue line with a PVA is to use Titebond 50 or other high resin content hard curing industrial PVA's made by Fuller and others. I have some face lams that I glued up with Titebond 50 in the early 1980's. Their glue lines are still as flush as the day they were machined. Glue color doesn't matter. Some of the hardest curing PVA's are white. No yellow or brown colorant, which is what they add to create Titebond.

hide glue is fairly rigid but it is moisture sensitive. It definitely can bleed through depending on your application. Usually good scraping and sanding will remove the bleed through and allow for uniform stain. Do a sample test to be sure.

That is very informative, and I am ordering some Unibond 800 from your website today. I have two questions: 1. when to use the bleed blocker, I am using a lot of walnut burl and olive/ash burl - would I need a blocker for these? 2. do you put little bit of Unibond 800 into the seems before putting the veneer down? I do this with Titebond - otherwise I get visible lines on the finish. How do you deal with that with Unibond 800?

Excellent excellent tutorial. I'm a very ambitious woodworker and just took a job building 10 doors for a medical center. I'll be veneering walnut veneer over solid plywood core doors. Pretty much convinced the urea glue would be the best... So, in my 78-ish degree F. shop with high Florida humidity do you have a ballpark open work time for the urea glue? I'll be doing 7' by 36" doors, obviously each side applied and cured separately. Also I'm somewhat concerned with bleed through. I'll use the minimizer additive, but how easy does the bleedthrough clean up after curing and what problems am I going to have with staining and do you have a stain type or brand recommendation? Lotta questions, I know so thank you so much in advance! Loved your video!

I saw a video or a man using Titebond glue to attach a paper backed veneer. He applied glue to both surfaces (in this case an interior door) then let them dry, like you would for contact cement. He then used an iron to heat and reactivate the glue and press it down. He seemed happy with the results. Any thoughts on this method? No press or clamps required.
@VacuumPressingSystemsInc
@VacuumPressingSystemsInc 3 жыл бұрын
I am familiar with this technique and not much of a fan of it. Two things. Its not the way this type of glue is intended to be used and the bond is definitely not as good as when proper clamping is applied. Second, a significant amount of stress is put on the veneer by the kind of heat an iron will put on it. This can weaken the bond between the paper and the veneer as well as the localized heat can cause the veneer seams to sometimes open up. Yes, I understand when you don't have a press this method allows veneer to be applied, that doesn't mean it's a good method. If it was me I would relegate this technique to edge gluing veneers when its difficult to use clamps. Large surfaces is asking for trouble.

Great info. But, what if you *want* some flexibility? ie. glueing a burled walnut veneer to solid wood. You expect the solid base to move with seasons and I would think that a rock solid glue would cause that to fail?
@VacuumPressingSystemsInc
@VacuumPressingSystemsInc 3 жыл бұрын
it somewhat depends on the overall size of the piece your veneering, larger the piece, more the movement. The more important issue is that the veneer's grain direction follows that of the solid wood substrate. A burl veneer with the grain going in multiple directions is more likely to cause fizzuring on top of the solid wood, than the issue of the rigid glue.

Logically you would think that to be the case, but most exterior glues are quite rigid, like epoxy and resorcinol. Exterior glues are thermosetting, mix part A with part B, making them very hard. Interior glues, in general, are the softer ones, which is why you get “cold creep” with interior glues, but not exterior ones.

Unibond 800 is an ultra low formaldehyde glue, with that said there is a small amount of exposure when using this type of glue. A respirator is always a good idea and decent ventilation. Its using large quantities that can become an issue. Most woodworkers I am speaking to are using small quantities in general where serious health concerns are minimal as long as good ventilation and lung protection is practiced. epoxies and urea resin glues can be hard on tooling. I suggest carbide blades and bits for dealing with these two glues.

Unibond 800 contains only .4% formaldehyde which is considered an ultra low formaldehyde glue. When catalyzed 99% of the .4% formaldehyde is locked up in the chemical reaction which means the off gassing is negligible. With that said the very small amount that does off gas is generally gone in about a week.

There is some confusion about material properties here. For instance, hardness and rigidity are two different things - one does not necessarily correlate to the other. I know that doesn't seem intuitive, but it's true. Some engineering terms that would be helpful to research would be material hardness, brittleness, and elasticity. I think the property of the area glue that is most important here is its lack of elasticity, or its high modulus of elasticity (or high Young's modulus to use a different term for the same thing).

I'll some of you some time -he says at a little after 13:00 that If you are using a wood backed veneer you can just use a PVA glue.

You talked about the value of a long open-work time, but then you said you designed your urea glue to set faster. Somewhat confusing. Without any mention of actual working times, it's hard to compare.

How about CA glue?

CA glues are great for spot repairs, but are generally not used for veneering and laminating.

@@VacuumPressingSystemsInc Thank you for a prompt response! I am aware that they are usable for repairs, but what could stop a random diy-er in using it for larger area veneering, as it ticks all tbe properties boxes?

@@VacuumPressingSystemsInc namely, my first veneering project (an 80-90''s dining table) went awfully wrong, as you described in the video, while using contact cement glue, and I actually repaired ALL of it with using humble superglue (in large quantities), and another coat of lacquer. Therefore I wonder could I use that glue at first place in some future projects?

Great, great knowledgeable video, thanks for every bit of info… but the wall behind you is frankly depressing. Could you pour in colors, shapes and personal memorabilia?

@@VacuumPressingSystemsInc Man! So sorry, I didn’t mean to come up that rude! It’s just that I’m 43; so basically I’m way more into content than aesthetics, but I was also raised by the likes of French MTV, cartoons and gaming systems, so my expectations are at medium, medium-rare, when it comes up to a YT decor. In other words, I don’t think that your set reflects the extent of your knowledge. In my opinion, anyone below 30 will pass on your vids within seconds, and that’s a shame. So, sorry for not giving you the key to my comment. And thanks again for a convincing exposé.

Excluding surfaces expected to get wet, hot hide glue is still your best all around veneer glue. No vacuum press, no clamps, just a veneer hammer (a simple squeegee) If you screw-up, just wet it, remove it and try again. Be sure to buy the heater element and the granulated glue.

Without a doubt hide glue is a great veneer glue. It's been used for a long time before modern glues became popular. The fact that it is reversible has its benefits, especially in antique restoration work. There are a few reasons why it has fallen out of favor and why I only gave it a mention in the video. First, it's a fussy glue to work with and takes an extra skill level to master well. Second, you don't have the open work time that you do with other glues, making it somewhat limited. Better for smaller panels, and like I said, great for antique restoration work.

@VacuumPressingSystemsInc I've seen veneers applied to curved, vertical surfaces while standing on a ladder using hot hide glue. The little heater element was perched on the ladder paint platform. It was about as complicated as hanging wallpaper. I don't know any other glue that would have worked. Veneers that were misaligned were simply wetted down, pealed off, and reapplied. Today, hot hide glue is notoriously overlooked.
