This heavy paper was hung with solvite packet paste. The paper seemed to soak up alot of the paste after 15 mins soaking and was hung. In parts, the edges (2-3mm)seemed to curl up when on wall (I know they were pasted carefully!!). I think I had the paste mix slightly too weak and would probably use ready mixed paste next time. Q1-Does what I am thinking make sense or are there other possible issues? Ready mix paste just seems too thick to do the soaking process correctly-hence paper expansion issues. Q2-Does the 15 mins still apply to this type of paste? Thank you.
