Title: Titebond 3 curing time
Post by: ccase39 on February 07, 2019, 01:46:08 pm

I usually wait 24 hours for the glue to dry when I use Titebond to back a longbow. I have never had a problem . Yesterday I used it on a R/D bamboo backed ipe is 24 hours enough or should I go longer?
In the past I have only used Unibond for R/D bows.
Thanks!

Id give it another 24 hours with the ipe. More is always better than less in terms of wait times for glue drying.

In my experience the PVA glues will get harder for about three or four days.

Ipe is the only wood that I know of where tightbond I is recommended. I imagine 24 hours at least. I am not recommending what I have done many times but on hot summer days I take them out of the clamps after about 5 hours and take them to floor tiller. Damp weather 2 days minimum. I try to let them dry at least at room temperature. I normally glue them up 1 day and finish them the next unless it is damp weather. This is assuming perfect glue lines. It makes a big difference. You figure a glue line is less than .001 thick, if the wood is dry it will dry quickly.

Do Titebond type glues only "cure" by drying or is there some other molecular stuff going on?

DC, TB glues first have to dissipate their moisture before curing. Those two things may work at the same time or one before the other but the moisture has to leave for the glue to set.

Hi,
I have used Tightbond 3 for years.  Of course for me it is gluing flute halves together although I have used it to glue skins to bows as per excellent instruction from the famous instructor Pat Brennan.  With the flutes I use electrical tape instead of clamps and find I can remove the tape after a couple of hours but I let the flutes set for 24 hours before working with the flutes.  With Ipe or any oily wood whether gluing flutes or bows I highly recommend cleaning the parts to be glued with Acetone first.

I would heed to pearl's advice.
If you clamped it you will probably be OK in a couple of of days.
But if you wrapped it with an inner tube it could be as long as a week. I'll never do that again.

I'd say it should be OK by now.  ;D
