Hey there, I have a steel frame dome and I'm about to build a cover over it for winter, so my idea is this ...

I'm going to secure chicken wire around the entire frame and then make a hydrated lime slurry with textile fibres and pack it onto the chicken wire with about a 10cm thickness, then giving it a finish to seal it when completed. I've done a test run in a hessian sack and it dries tough and light. Has anyone had any experience with this kind of build technique or point me to any information where I can further my knowledge on building with hydrated lime mixed with either wool/textile fibres, hay, wood shavings etc.

I would love to know more if anyone can enlighten me.

Millo,

I use lime plaster a lot, but do not try to make thicker structures out of it.
I use lime putty (that I prepare from high calcium lime) and mix it with sand and chopped rice straw.
Two things - I have read that using wool fibers will make them clump into a ball during mixing. Traditionally the wool fibers were introduced to small amount of lime plaster that was just supposed to go on the wall.
Second thing is - lime needs carbon dioxide to cure, so thick layer may have problem to absorb it.
For thick lime layer I would probably add some pozzolan material - brick powder, calcined clay, pumice, or I would work in layers, let's say no more than 2 cm at a time.

What is the purpose of covering it?
Function is an important part of process.
