I've just watched a TV programme showing a small garden wall being built
from breeze blocks. The wall was roughly rendered when finished. Is this a
sensible thing to do as I was under the impression that these blocks were
for 'internal' use only? I remember leaving a few of these blocks out in my
garden and they disintegrated quite quickly. Is the render sufficient to
make them suitable for external use or are the people in the TV programme
mistaken?

Any thoughts on the subject?
