That's exactly what I needed to know thank you.

As frost pretty much rules out doing this for the foreseeable
future, can you do the pointing when there is frost about?

It doesn't need pointing if you are rendering it, but whichever you
decide to do will have to wait until it's been above freezing for at
least 72 hours as deep frost inside the wall will take at least this
long to thaw. Whichever you decide to do, you'd be wise to add some
frostproofer and hardener (B&Q or any BM) and only mix it in small
batches as it goes off quickly

er... if the inside "core" of the wall is at -1 and the surface at say
+4 why would you have to wait until the core defrosts before rendering
the surface?

Because the moisture frozen inside the wall has expanded, and when it thaws
it shrinks....trying to render bricks that are still frozen on one side
isn't a good idea
