Guys, I use a bunch of different glues for different purposes. T2 is my general go to glue for interior stuff unless I want a darker glue line. Then I use T3 (for exterior as well). Both remain too flexible for any real veneer work. For almost 15 hrs I have been using Veneer Systems¡¯ PPR urea glue?
Water mix, tintable for lighter colored veneers, super easy to work, good open time, and ROCK HARD when cured. Zero spring back. Machines well (no gumming up router or shaper cutters). Also has a long shelf life.?
We make this table with 16 resawn ?1/8¡± walnut plies. One vacuum-bagged glue-up and zero spring back.?
To speed up cure times we use cheap electric blankets covered with foil-bubble-foil insulation sheets.?
Best,
Fred Rossi
I was going to switch to t3 because I thought it produced a harder glue line (higher solids) which is preferable for commercial veneer, even though I have not had issues with t2 for 25ish years. These are the glues that i just happen to have on hand.
I did a little non scientific experiment and found that?
t2 is super soft/ pliable (no surprise) ?48% solids 10-15 min open
T3 is much more stiff but still bendy 52% solids 20-25 min open
T2 extend little bit bendy but snaps 49% solids 20-25 min open
So looks like my search for one glue does it all is over. Regular ol¡¯ titebond is more than adequate for indoor furniture but would like more open time so will probably go with t3 for the open time and i think the color blends better with most woods, one thing I don¡¯t like is that its runny.
For commercial veneer probably stick with t2 extend until its gone then maybe try some of the so called specially formulated PVA¡¯s for veneer like unibond1. For shop sawn idk, I did a bit in the past but only when there was a frame surrounding the panel so I don¡¯t know if they creeped, the joints never opened as far as I know.
I don¡¯t really want to use a urea or epoxy.?
Also probably obvious but definitely need to mix pva if it sits for awhile (not sure how long). I wasn¡¯t thinking and just grabbed the t3 and t2 extend and the first ones i poured behaved differently, the t2 extend didn¡¯t break at all which i thought was weird so i shook them and re-did it.
Here¡¯s a pic and a vid¡
?Running out of glue and since I am much more in the shop now, thinking of picking up a gal of Titebond III. It is little more than their interior basic glue but I rather not have multiple bottles. TB III also has the longest open/assembly time of the 3 kinds they offer. All 3 have 2 yr shelf life with proper storage.
Any recommendations on this or other brands to consider?
