I have used newspaper before on areas of concrete floors to soak up excess moisture that has come up to the surface.We would put dry cement on top of the paper to give it extra "draw",works great. Somehow,I don't think that would work on Bonding coat plaster.If the float coat of plaster has set properly, there is an amount of suction on the wall which draws the moisture from the finish coat back into it,so any blisters etc are minimal. Bonding coat plaster can be notorious for being slow to set.The worst case scenario is when you put the finishing plaster on too early and it goes off (sets), but the bonding coat underneath, in places, has not properly set.You will get a surface of the moon effect,and no matter what you do,you only push the blisters down in one place and they come back twice as big in another. Let it set properly underneath, then no problems.
