Re: GSBN:Re: Lime plaster problems
G ' day Andy
My two rands worth mate.
You will need to remove the lime coat and scratch up the earth as
others have said.
I would then apply a mix of earth/lime/sand and chaff or chopped straw.
All depends on the clay content of your earth but I would look at
something like this 3 parts soil 2 parts lime 3 parts sand 1 part
chaff. I use buckets for this mix. It works well and binds well with
the earthen render. Then if you want you can apply a finish coat of
lime render however I have not found that necessary in most cases
except for look.
You can see a house we renedered with earth, then
earth/lime/sand/chaff, then lime/sand, here:
