I've just bought some wallpaper from a local paint/paper decorating

them regardless of "weight" had a little sticker on recommending that
ready mixed paste should be used.

poor adhesion unless it was used.

I told him that in 40 years of doing my own decorating I had never had
a need to use ready mixed paste whatever the paper, and so I bought a
packet or two of Solvite as usual.

I have never come across this stipulation before and wondered if
others have any experience of it, or can offer some logical
explanation (other than there is more profit margin on ready mix)

Well he has said the adhesion is better. Also, some vinyl papers are
not very absorbent which may cause a problem ?
But I wonder how easily you could strip a wall with PVA'd paper on it.
Would it "melt" like the normal stuff does with a steam stripper ?
Simon.

AFAIK Solvite is just CMC (carboxymethylcellulose) which IME doesn't
always do a good job on the edges of vinyl paper


I found that edges stay stuck better if theyre _not_ rolled down.
Rolling squeezes most of the glue out, so I guess you end up with less
paper to plaster contact area.

Manufacturers love their high margin extras.
