Hardback decorative binding cord detached. Pictures inside.

In this first picture you can see the headband is adhered to the pages correctly:

In this second picture you can see that the headband is not touching the pages at all. This is on the opposite side of the same book. Is there a special glue for reattaching?

UPDATE: conservation grade PVA glue is what I've been told

I use Jade #403 for that sort of thing and binding in general. It is a PVA and is safe to use: https://www.talasonline.com/Jade-403

On gaylord's website it says something about a 90 day shelf life for this product? Does this mean that once I open it I only have 90 days to use it all? I'm thinking this probably isn't the case but that's what it says. At the bottom of the description it says "90 day shelf life. Do not freeze." Thoughts?

>3 RickFlair:

If PVA is frozen, it may lose its gluing properties. That's why a lot of bookbinding supply companies won't ship it during the winter months.

Like most sellers/manufacturers, Gaylord is being pretty conservative about the shelf-life. PVA is actually fairly long-lasting, but you'll want to make sure that you have it in an airtight container.

>4 lilithcat: I've taken up to a year to finish off a pint of Jade PVA from Talas with no ill effects. I just keep it in the container it comes in which is airtight.

>5 kdweber:

Yes, "airtight" is the key.

>3 RickFlair:, >5 kdweber: As have I. If it sits unused for a while, it is a good idea to stir it thoroughly before using, as the ingredients tend to separate over time. However, if one is actively using it, that is not an issue.

>4 lilithcat: I will verify that! I accidentally left a small jar of Jade in the car one winter, and it froze, rendering it useless. Lesson driven home.

>3 RickFlair:, >6 lilithcat: And I've leaned to not buy more than I can use in a few months. I can always re-order when getting low. I once had a half-gallon of Jade 403 that I had used about one third of. It got lost in a move and so I ordered some more, but in a smaller quantity, as that half-gallon was really more than I needed at a whack. About two years later, I found the missing container. It was hard to get open, as the glue had set around the lid, but after application of some additional leverage, I got the lid off. The top 1/2 inch or so had set, but after removing this and stirring it thoroughly, the remainder was just fine. I used it all w/o any problems, but this is not really recommended!

Another trick with PVA is to mix a bit of it with wheat paste when pasting up the cover leather. It adds tackiness to the wheat paste and the latter keeps it from setting up too fast. I've done this many a time with excellent results.

I mainly use PVA for making slipcases. I use straight PVA to glue the box together but dilute the PVA with water to attach the interior velour and exterior bookcloth.

I just need to fix the headband on this one book. Then, I may not need the glue again for over a year or more. I guess I should just get the smallest bottle but still feels like a bit of a waste. Maybe some book specialist would charge me a few bucks for a quick dab of glue?

>9 RickFlair: To be honest, for just re-attaching that loose headband, you could get by with a dab of Elmer's glue, but go easy with it. It is a PVA, but isn't very flexible when dry, whereas Jade is flexible. No, it isn't heresy! I have done this a time or two myself. Just use a thin layer.

>10 Glacierman: Not recommended, Elmer's glue is acidic.

>11 kdweber: Ah! That I did not know. Never too old to learn something new.
