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

I asked him why and he said the ready mixed paste is PVA based and
the manufacturer of the paper would not consider any complaints of
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)
