What were the thinking?  I now have the diagnosis and now I need a cure.  Calcimine (Kalsomine) was the finish of choice in my house a long time ago and now it is rearing its ugly head.  For those of you who are not sure what calcimine (Kalsomine) was be thankful.  It was a dried calcium carbonate product that, mixed with water and sometimes pigments and glue, formed an opaque, easy to use and fast-drying coating for walls and ceilings or so they say.  Basically it has become the perfect nonstick surface in my house the paint is coming down and I need a approach to deal with it.  Any suggestions will be appreciated.  There are 1000’s of sqft that are affected so it looks like this is going to be a long term project.  The lady who used to own this house sure liked to paint,I would guess that the paint varies from 1/16 1/8″ thick and all of it is lead paint.
