Hi Guys,
We beat the Wall paper issue to pulp many many years ago.
I am in the camp that one should not use wall paper Glue, It think it's called Shurestick 5000? or something like that.
The chemicals used for mold/mildew protection in Wall paper glue is probably not good for Vintage poster paper.No long term data exists.
Call up a a museum or a paper tank and ask if they use wall paper glue. They'll hang up on you!
Nori paste has been tried and tested for a very long time and used by most paper restorers.
I think it is to cut corners, Since Nori paste involves cooking and cool down/cure, good to go next day. No sooner.
Sugar?? After all these years that is news to me. I think I keep it for my
.
Other than that Charlie got the paste down. Yeah you want to land a bit higher on the Ph indicator Ph8-9-10
All the best,
dario
