Why is this adhesive so freagin' expensive?
It could be corporate greed. The manufacturer of the plastic buckets recently tripled their cost to nearly $8 each. The bucket is very durable and it's great for storing/mixing the glue, but the price is just ridiculous. Then there is the powder itself which has suffered approximately eight price increases in the last three years. The most recent increase was nearly 60%. From what I understand, there is only one manufacturer of PPR glue in the USA at this point, and they have chosen to distribute it through just one wholesale company. So they have an monopoly now and can charge any price they wish. It makes me sick. I'm pretty sure that no matter where you buy US-made PPR glue these days, it is all originating from the same manufacturer.

Is this adhesive the same as DAP/Weldwood powdered urea resin?
It might not be identical but it appears to be very, very close.

Where can I find a chart that shows all of the Better Bond veneer glue differences?
This downloadable adhesive chart shows all of key points about each of the Better Bond veneer adhesives and may be helpful when choosing a glue for your next veneering project.

What is the shelf life of this adhesive?
The powdered Ultra-CAT adhesive is will remain usable for 8 months if stored in cool and dry conditions. If left unopened, most users can expect up to 12 months of shelf life. We have heard from customers who have used this adhesive without issue 18 months after purchase.

How can I tell if my PPR glue is past it's shelf life?
You will notice that the powder will not mix well with water. It'll be like pouring water into sand.

What is the shelf life of the lightener?
The lightener shelf life is indefinite.

Is this adhesive freeze/thaw stable?
Freezing will not harm this product.

Can this adhesive be used for general purpose woodworking?
Yes. This glue is excellent for standard glue joints especially since the glue line will have a wood tone.

Can I order just the lightener part?
Yes. Simply type "lightener" into the search box on our site to find it.

What does PPR mean?
Plastic powdered-urea resin.

Can I use this glue on paperbacked veneer?
Yes. Thoroughly scuff the back side of the veneer before application to allow adequate penetration of the adhesive.

Do I need to apply this adhesive to the substrate and to the veneer?
Always apply Ultra-CAT adhesive to the substrate only. Do not apply it to the back of the veneer.

How much pressure is required when using this adhesive in vacuum press?
The ideal vacuum level for Ultra-CAT is 18 to 21" of Hg.

What kind of finishes can be used on a project that has been veneered using this adhesive?
You can use shellac as well as water-based, oil-based, lacquer-based, and alkyd-based stains and top coats. Do not flood the surface with the first coat of finish. Apply a light coat and allow it to dry. Then proceed with heavier coats of finish as needed.

What filler can I use if my project surface has gouges in it?
Wood fillers typically create a non-porous surface. The problem is that water-based adhesives do not bond very well to non-porous surfaces. When the filler area was minimal, I've had success with both Bondo and with Elmer's "Stainable" wood filler. I've also had success with Durham's Rock Hard Water Putty on somewhat larger substrate defects. Be sure to scuff sand the filled areas with 60 or 80 grit paper to get maximum bond strength.

Is Ultra-CAT PPR glue CARB compliant?
There's a lot of gray area here according to our supplier since much depends on your interpretation of the CARB rules. The PPR is a urea formaldehyde adhesive, so if you use it, you are adding urea formaldehyde to the panel, which the CARB ruling does not allow. However, from conferences and the like that my supplier has attended, the rule is directed at the core stock, with the intent of getting panel producers and users to only use core that is not made with UF resins. UF resins have been the choice in binders of engineered core stock for decades. You'll see these compliant core stocks referred to as NAUF (no added urea formaldehyde). ULE (ultra low emitting) UF resins have been developed and can be used, but they have to be certified. Ultra-CAT PPR is not a ULE resin.
