Ply,breathable paper, batton then mesh?

[Phoebe]

Just doing a pot of rendering and was advised to use a breathable paper. Should this be straight on ply then battened on? Or ply battens then paper?

If ya on about using a lath mesh then i would go ply, batten, breathable membrane then mesh. The breathable membrane behind the lath lets the render push through the lath and grab onto its self. .....roger that..over and out ........:RpS_thumbup:

why is the batten in front of the ply? then the lath over that

It is almost certain to crack if the lath is fixed directly to the ply, I don't know why I just know it does.

Better off using rib lath and paper :RpS_thumbup:

with a batten and then lath you will be looking at some thick render - which is almost certain to crack

render board thincoat/mesh it all done before you even finish ply.

on the very rare occasion we have rendered over ply we have used paper and lath coated up and then full meshed with a bagged polymer render scratch coat then coloured finish

but as a rule I try to avoid any kind of wood-render-S&C combo

It's a bit like the American (maybe old) stucco system on timber frame. The building paper gives something to push against, used chicken wire spaced out from the building paper with special nails which had a tar impregnated paper spacer to hold it clear of the building paper. Thick rendering. Seemed to work OK, but probably better systems now.

Rendalath from Bekaert Link Removed is a ready prepared system which should take render more easily. Rendering boards and the various thin coat systems seem like they may be an easier solution.

Others will have to advise on how good the different ones are.
