Re: GSBN:What type of sand?



Dear Andre, Frank and others,

back from sandy coast in Brittany I see your mail on that sand. I got that
sharp sand advise from a manufacturer of lime, as they did some tests on the
right sort of sand. Would like to encourage asking the manufacturers on
what's best in view of local options.

Frank answered observations which I share. Returned from a straw-bale
project in Brittany where "karolin" sand had been used, which did not work
fine. Also the walls had not been build rather straight, so the amount of
stucco got to heavy and some of the stuccoing had to be redone. They did not
shave the walls and just sprayed the lime on the walls. Luckily the owners
are easy and flexibel in restoring, now they would inform better at the
beginning of a project.

Best wishes for 2005,

Martin
