Hi
This is my first posting on this site. So firstly let me say hello, and introduce my self.
I must point out that I am not a plasterer, but I hope to be a customer of one shortly.
We live in the south west and are having a timber frame extension built, and I liked the idea of rendering onto mesh rather then a block and render finish.
The spec calls for horizontal and vertical battens fixed to the osb, then stainless steel mesh and then a 20mm sand and cement render.
Now there are two things I cant get my head around.
Firstly all that I have read on the net about the subject mentions a minimum 25mm air gap behind the mesh for ventilation, but if the battens are fixed horizontally and vertically how can air flow freely.
The second question I have is am I right in thinking that a layer of breather paper gets layed between the mesh and the battens. I think this is to keep the render from falling into the air gap. I asked the chap who has priced the rendering for me about this and he says no.
He has priced for ordinary SS mesh not rib lath.
Since I have been looking on this site I have realised that there are other options to SS mesh, but the plans have been signed off by the building inspector so I don't know if we now have to stick to the spec as approved.
Hope all this makes sense. I had good look at other posts about timber frame but none covered my specific questions.
