Historically galvanised Expanded Metal Lath (EML) was used for
supporting external render as well as internal plaster work. More
recently the advice seems to have shifted to using stainless for
external work.

What are the thoughts on the life expectancy of galvanised EML used
under traditional render in non coastal locations?

Anyone bought any stainless recently? If so how much did it cost you,
and where from? (some of the prices I have seen online have been plain
daft!)

if the render is sound, the galvanised stuff is almost completely out of
damps way, and mostly fairly embedded in the render.

Now we know that split hazel and cowdung lasts a couple of hundred
years..so I would think galv steel will be at least no worse..;-)

==========================================

I removed the render from between upper and lower bays a few years ago
because it had developed a number of cracks. The render appeared to be
original and about 60 years old at the time. The galvanised mesh was in
very good condition (extremely difficult to break up), so I would think
that it has a life expectancy of at least 50 years in most conditions. The
cracks in the render appeared to have developed because the render was too
thick and heavy for a vertical surface, rather than failure of the mesh.

I would think that galvanised is marginally easier to use than stainless
because stainless is so shiny and slippy compared with galvanised.

I went with ss a few years back, cost around 7-9 a sheet, I think
probably from TP - all slightly hazy memory though, could be wrong. On
a rendering job it doesnt add too much cost and ensures a long lasting
result, I thought it the better gamble.

Yup, I had found that... not much use for answering my specific
questions though.
