[Strawbale]lime and earth plaster

[j-verzijl at dbafm...]

Hello,

This question is not exactly relating to bales bud it does to lime and
earth plaster.

We are renovating an old house and have plastered our walls with earth
plaster. Most of the walls contain tubes witch are connected to our
central heating system. The walls itself are made of f brick as is the
foundation. We have a lot of moist climbing up from the walls and some
areas won't dry. There seems to develop some white powdery fungus on the
lower part of some inner walls. We thought about stripping the lower part
of the wall and use a lime plaster instead. Would this solve our problem?
Because the walls are heated I am also afraid there can be some cracking
between the lime and earth plaster because of the differed shrinking and
expanding could this be a problem? 

On the subject of lime and lime putty does anybody know how this is called
in Dutch and where I can get it?
