Rendering using Isovit eCork

[filipe]

Hi there,

Has anyone used Isovit eCork to render external insulation (over wood fibre)?
I understand you need to do a layering of 3mm then add the mesh, then another 3mm. What is not clear to me is whether you let it fully dry between layers, or is it done in one go.

Thanks.

I used it as a bonding filler to stick wood fibre boards to the wall then lime hemp mortar in two coats with the mesh between. First 3mm coat press then mesh into it and second 3mm coat the same day. Are you talking external work here?

I got some exterior and some interior areas. I also used it as adhesive to stick the boards to the walls.
Ok, I suppose 6mm in one go wouldn't be a major problem in terms of cracks, etc. Specially given the mesh inside.

Thanks for sharing.

Externally, I take it this is to do next Spring ?

That is what I thought until I looked into the forecast last night. There seems to be some days ahead with temperatures above 5C. I might have a chance to render it once for all.
