over the last few months i have been watching a team of builders
erecting some new timber frame dwellings,all the outside looked like
marine ply and when i looked again a few days later they had been
rendered and looked brill,how did they render on to the ply outer?,has
me beat !!
Have a look at some American construction web sites and all will be
clear. They typically use wire mesh and stucco.
Now whether you think that looks "brill" is something else.
"Little boxes, on the hillside ..."
"And they're all made out of ticky tacky and they all look just the same."
Nail expanded metal lath all over it. That will then take a conventional
was quite anal about ensuring the lath was well and regularly fixed on
mine. However, while I was doing mine, I was also watching a set of
builders doing another conversion a little way away - got a nice
viewpoint from my scaffold. The renderer there just used a carpet
fitters stapler to fix some building paper over the ply, and then again
to hold the expanded metal lath. I was surprised how little fixing he
gave it (ten staples per 8 x 2' sheet maximum perhaps. Still there
render is still there a few years later.
More details of lath use here:
Easy enough with the Bosch multi material bits...
The only particularly interesting hole I need to make through it was for
a soil pipe. The combination of render, expmet lath, ply, PIR foam, and
plasterboard made for an interesting 130mm hole!

A neighbour (who is also a builder) externally lined one of his
9" walls with PIR sheets, then chicken wire, and then rendered.
I didn't see how the chicken wire was attached -- might have
been battens between the PIR sheets, and I would guess he used
some type of bonding to make the render stick to the PIR too.
It's still all there 20 years later.
Not usually too fond of 3/4" of sand and cement render though!
(in the end I chain drilled the outline of the hole through the render,
and SDSed the render off the hole, tinsnipped the expmet, and stuck a
big bimetal holesaw through the rest)
