<font face="Calibri">Dear Kitta,<br>
<br>
I am not sure if they have maintained the plaster with the regular
lime washes, as I haven`t asked, but this happened to a few houses
this old and I would say at least one of them must have had an
orderly housekeeper to maintain the plaster properly. As far as I
understood the problem of the plater was not the cracking itself,
but rotten straw underneath to which the plaster is attached which
caused the plaster to shear in whole layers. I reckon lime plaster
needs to be maintained with lime wash every few years (perhaps
every year?) otherwise you have problems with cracking in the
future. </font> <font face="Calibri">But I was addressing
different problem here: straw rotting underneath the otherwise
healthy lime plaster.<br>
<br>
Regards,<br>

Jure,
<div><br>
<div>Did the owners maintain the lime plaster with regular lime
washes? Are the bales actually rotten - all of them? Did it
happen gradually or all of a sudden after a really bad winter
(like last year in Scotland) with wet weather followed by
freezing weather?</div>

I have in interesting information. I have spoken to a
guy who does<br>
natural plastering for over 20 years and he said that
the houses in<br>
Austria which he worked on 20 years ago show problems
now. The plaster<br>
which was applied directly to the strawbales on the
outside is cracking<br>
and falling off and they found out because over the
years some moisture<br>
got inside the straw and made it crumble and dissolve.
So the house is<br>
no good now and there is no easy way to repair it. I
wouldn`t like my<br>
house to live the same misfortune in cca 20 years
time. This is why<br>
vapour barrier and wind proof facade is a good
solution. I can`t wait to<br>
hear your comments.<br>
<br>
Cheers<br>

the underside of these bales. So why do it for wall's
if it's not done for the roof? Any thoughts?<br>
