Ultra-CAT™ is a high-solid content, plastic powdered resin veneer glue with an extra long open time developed using catalyzed adhesive technology. This adhesive cures rock-hard and leaves a glue line that withstands heat and moisture. Ultra-CAT is highly sand-able and works particularly well with wood types that are prone to bleed-through such as burls and open-pore woods.
Ultra-CAT has a non-evaporative curing process which eliminates 'veneer creep' caused by seasonal humidity changes so joint/seam lines never separate. Ultra-CAT glue will permanently lock-in the form of curved and contoured veneer projects making it ideal for all custom furniture projects and bent laminations.

- Model aircraft construction
Pricing: 5 lb Pail - $24.95 25 lb Bucket - $79.90
Coverage: 200 to 250 square feet per 5 lbs of powdered adhesive
Minimum Use Temp: 70° F
Curing Time: Full cure in 4 to 6 hours at 70° F
Speed Curing: Some vacuum press users have placed a heating blanket (set on 'low') over the vacuum bag while the project is being pressed to accelerate the curing of the Ultra-CAT adhesive. Curing time can be reduced to 2 hours with this method!
Optional: Ultra-CAT Lightening Agent
Simply add this highly effective powder to Ultra-CAT to dramatically lighten the glue-line color. Ideal for maple, sycamore, ash, and other light woods where a dark glue line would be unacceptable. The powder is inert and has absolutely no effect on the quality of the bond.
Powdered lightener is most often combined with Ultra-CAT™ adhesive when used with maple veneer. To minimize glue-line visibility with most maple veneers, we suggest a ratio of 1 part (by weight) of lightener to 10 parts (by weight) of Ultra-CAT adhesive. For medium toned veneers, use less lightener.

Tip from Joe: Don't forget a glue roller. It's worth every penny!

This is now my go to glue for bent laminations and veneer jobs that require extra toughness. I did a pretty tight radius with strips of hard maple and got next to no spring back. I was using Uni-Bond but I am sold on this glue and as always, I got great service from Joe!

Ultra Cat PPR is the ONLY glue we use to build our high performance sporting equipment laminations. This stuff is amazing and dries rock hard for NO warping. THANK YOU!
Review by David Hirte
A great glue! We use it at Summit Door to build rail and stile doors. Quality is consistent and dependable. Warm it a little and it sets up in a matter of hours.
Review by Taylor Russel
Finally, I'm using this for bent laminations on my rockers. Before this, I used resorcinol but the fumes are too harmful. The Ultra Cat works just as well and costs less so we're now buying this from Joe on a regular basis.
Review by Joe K
Used just last night. Not as convenient as pre-made glue but it really is no big deal to make up. Directions are clear and it's easy to get a good consistency. Stuff bonded my veneer great. I only made up a 1/2 cup and had no problems. Stuff should last me a while. I'm doing thicker home-made veneer so Joe recommended this for a long-lasting bond. From every indication.. that's what I got.

Recently I was making a large reception counter for a CPA firm that required bent lamination panels. I ended up having an extra 50" radius vacuum pressed panel. It was made of two 1/4" panels of bending ply faced with walnut veneer. I attempted to salvage the unused veneer from the panel by soaking the whole panel in a large tub of water hoping the glue would break down and gently release the veneer. After 5 days underwater and no release I gave up. I know the product states water resistant, but I thought that was especially good as it held up even with the pressure from being bent. And it still had its same shape.

This adhesive is amazing in every way. I've been using it for bent laminations on headboards that I build for a local furniture business. I was previously using Unibond-800 and I just could not stand to see the toxic warning labels all over the bottle everytime I used it. It drove me nuts with worry about keeping the air ventilated in my shop. That is hard to do when its 40 degrees outside and you need to maintain 70 degrees for it to cure.
The Ultra Cat still needs 70 degrees to cure but its much less harmful than Unibond-800. It works equally as well but it costs much less. I ordered two 5 lb units of Ultra Cat and shipping was around $13. The order was shipped about 8 hours after I placed the order (which is pretty quick when you think about it). Over all, I'm a very happy customer and the Ultra Cat really works out well.

I've switched to this as my main veneering glue. I sometimes use it for other gluing tasks as well. Easy to mix. Rolls out evenly. A nice rigid glue line and sandable too.
Review by Craig Lester Sr.
I read about this glue on an online forum. The OP (original post) was from a guy who wanted to make a bent lamination sleigh bed. Nearly everyone on the forum brought up the UltraCat glue as a suitable glue for his projet. He later posted his results and he wrote about how well this glue worked for him. His words stuck with me and so did the comments of the other forum members. I tried out this glue and all I can say is that its very easy to use and the strength of the bond is comparable to epoxy in my opinion. The squeeze out glue I had was rock-solid. It sanded off well too.
Review by Donald Macintosh
I've been using Unibond in my shop for years and its always worked well (though sometims has a fair amount of bleed-through). It's a great adhesive but the fumes are incredibly toxic. I recently switched to UltraCat and have found it to be a better glue for veneering and is notably less toxic. During the cold winter months when I cant open the shop windows, its nice to know I dont have to worry as much about the fumes. And the UltraCat bond is just as strong as Unibond.
Review by Will Berkmieser
This is the finest veneer glue available. It takes some time in the vacuum press bag but the results are exceedingly satisfactory. I've been using it for several years and I've never had a veneered project come out bad because of glue. I've used at least 10 containers so far and each has been fresh and ready to go. The instructions are top notch and the price is a dream. I am one happy customer.

This stuff works great, with a balanced set up time to finished press time it all comes together perfectly. Mixes easily, rolls smooth. I'm back for more!!

All I can offer for a review is to say that our company uses about 10 of these pails every 3 months to build high-end custom entry doors. This is the only glue on the market that gives an incredibly rigid glue line. For us, it helps prevent doors from warping. Yes, its a veneer glue but its also one helluva good general purpose wood glue when you need unmatched strength.
