RE: GSBN:Re: Lime plaster problems

Sorry to chime in so late...been busy. Its just that I haven't seen anywhere
that in the responses to remind Andy that it is very important to wet down
as well as scratch the base layer of plaster before applying a new coat, and
if the material is different (lime on clay in this case) really rub the
first bit in so it binds well.

Hope your problem has been solved.
