reattaching a separated rear pastedown

I have a copy of the 1987 Folio Press Milton poems where the rear pastedown has mostly separated from the boards. It looks like the glue dried out. It seems to be a simple enough repair job that I could probably do it myself, and the fact that the pastedown still has a small attachment means that the paper naturally settles into the right position, so I don't really have concerns about misalignment due to lack of tools to hold the book in the proper position while the glue dries. I did some research already on the best approach, and it seems like a neutral pH glue is the most important consideration.

I found the following glue recommended for book repairs:

"Lineco 901-1008 Neutral PH Adhesive"

While the discussions I read online were mostly about repairing cracked spines, I see no reason why this glue would not work acceptably for a pastedown as well. My one major uncertainty is the best position to let the glue dry. I suspect it would work best to use some small paper clamps on the top and bottom of the boards near the spine to ensure that the paper doesn't shift and then leave the book open to the rear endpapers while the glue dries.

Before I go ahead and buy the glue and attempt the repair, does anyone have any additional advice or recommendations?

Here is the current condition of the book (click for high resolution images hosted by another site):

As a hand bookbinder, I am more familiar with Jade 403 (a PVA adhesive). It will do the job quite well and is safe to use. Unless I'm pasting leather to the boards/spine (for this I use wheat paste), it is what I use exclusively. I've linked to a source above.

However, it appears that Lineco's product you mentioned is basically their version of 403--it too, is a PVA--I don't see why you shouldn't give it a try. I do note, however, that Jade 403 from TALAS (link above) is $3.50 less than the Lineco purchased from Lineco; $7.50 versus $10.80 for an 8 oz bottle. I have no idea how the shipping compares.

You should definitely do this yourself. Just take your time and do not rush it. Be sure to insert a double piece of waxed paper between the newly pasted down endpaper and the free one, then place the book under weight for oh, a week or so while it dries. Two or three heavy tomes should do the trick. Don't be in a hurry to check it. If it is still a bit damp when checked, put it back under the weight for a few more days. Patience is definitely a virtue here.

RE: PVA - Be aware that if PVA freezes during shipping, it's useless. So depending on where it's coming from and where it's going, that's something you should consider.

>2 Glacierman: And she is very, very much correct! I believe TALAS won't ship Jade during the winter for that reason, but I may be wrong.

Edit.
Here is TALAS' statement regarding their PVAs: Be advised that if this product freezes in transit, it will be rendered useless. Depending on your geographic location please take this into consideration when ordering. We hold orders and release them at times when weather permits, but we unfortunately are not able to refund orders that freeze in transit during winter months.

>3 lilithcat: thanks; that is good know because I am in Canada and right now any package that spends much time outside will probably freeze.

Great advice so far. I'd thin the PVA with some water making it easier to apply and probably resulting in a smoother application. I use a glue brush to apply the thinned PVA and a bone folder to smooth out the paper rather than a roller.
