Two years ago I started a project - since interrupted - because the old
wallpaper was curling at the seams. Now I notice that the paper I hung is
doing the same. I assume level of humidity and skill of the paper hanger are
the major factors. I know for a fact the original stuff was done by an
amature. Though I'm no pro, I hung a few rolls over the years.
The house probably does swing to low levels of humidity from time to time
despite a humidifier (Ohio) and dehumidifier. I tend to think the root cause
is probably me; I may have rolled the seams too tight... if that's possible.
Any experts out there who have an opinion of the root cause? I suppose the
remedy is just get some paste, pull back the curling edges a tad, slap some
more paste on the wall, and reroll.
I also live in Ohio and had wallpaper long before I had a humidifier. I
have not had any problems with edge lift.
The first thing that I would suspect is surface prep. What was the
surface like that the wall paper was put on? Did you use wall sizing or
other sealer on the walls before hanging the wallpaper?
talked to several wallpaper men over the years and found out that the
seams will roll up after time if you used too much pressure with the
roller over the seams... this just squeezes out the glue that is needed
to keep it in place... i have learned the hard way and will never
forget... so trying to get the seams down by pressing real hard is just
hurting it....seems like it would be the opposite... live and learn.. i
am learning all the time by my mistakes..
Looks like the root cause is... me. Too much pressure on the edges when
applying the paste. The surfaces were properly washed with solvent and
sized. I do remember applying a LOT of pressure at some of those edges
thinking I was going to hide the slightest hint of a seam. Well... that
didn't work out too well. I assume I can lift the edges and repaste. Only
concern is... those curled edges may have memory by now. If that's the
case... my first thought is... duct tape to hold in place until the paste

Comes in a squeezy tube with a narrow nozzle. Squirt it along the lifted
edges, gently roll. It's thick and goopy and requires a extra rollovers
or damp cloth wipeovers as it dries.
It does a good job. I just re-seamed a number of edges on 15+ year old
paper in my dining room. Similar humid/dry cycles here in MIchigan,
with steam radiator heating making humidity control very difficult!

As far as memory, brush it in & let it soak for a little bit. Once it
soaks the paper will relax.
Take it from a pro.
I'd suggest a pre-mixed clear, you can get a quart or smaller.
Thin a small amount down to where it's... ummm.... maybe like...
spilt pea soup. Brush it under there. If you get too much resistance
trying to push it out its likely too thick.
You should recognize when you have the right consistency.

It likely shrunk a little bit too.
The longer you let it soak (without letting it get too tacky) the
more it will expand.

Since you probably don't have a heat gun lying around, a hair dryer is
the next best choice.
I'd bet this is a pre-paste.
Pre paste's have varying degrees of glue on them.
The manufacturers that sell them suggest running them through a water

How heavy is the wallcovering..?
Each condition is different.
