Expamet - mesh or riblath?

[PikeyDIY]

We'll shortly be battening and counterbattening out our timber frame walls to receive a rendered finish. There are two types of metal lathing, one is just a diamond mesh (what I'd refer to as simply 'Expamet'), the other is ribbed ('Riblath'). In galvanised form anyway, the riblath is twice the price! Is it twice as good?

Galvanised is listed as being ok in an external environment in certain situations only. Our building is single storey, in a town, inland, sheltered by fences on two sides - will this be ok for galvanised? Stainless versions of these lathing meshes would cost us a four-figure sum of money

One more question - traditional cementitious render or modern 'throughcoloured' polymer/acrylic/resin type thing?

both systems good,this also applies to the render,its all price. mesh,sand/cement cheapest.

Well yes I know sand/cement will be cheaper - but fundamentally attaching something brittle to something flexible cant be all that good an idea can it? I mean I know the mesh will hold it all together but surely over time it'll just crack all to pieces?

render on mesh sets hard,its now reinforced,it will not break down.
