Hi,

* *I'm not an expert on emulsion - but I think the walls in a bedroom
are emulsioned with vinyl silk - there's a slightly shiny surface to
the wall.

sounds like it

Now centimetre wide "spots" of emulsion have come off and we
can see the plaster underneath. In places it is single spots others
it's more like a "rash". Now I can emulsion on top (any gotchas?) but
I guess the "shadow" of the lost emulsion will still be visible.

yep

How
can I "mask" or "fill" the spots before I put the final coat on? I was
thinking maybe some white undercoat to build it up first? Is there an
old-diyers knack to tackling this?

Many have tried, but theres no easy solution.

* *Also the old saw of "hairline" cracks. I'm a Tetrion fan - but it
is too thick for these cracks and I'm not keen on racking out bigger
cracks to give a surface for Tetrion to bond to. Has anyone used the
"inverted V" approach where the opened crack is wider "into" the wall
and still narrow on the surface? The idea being the filler won't fall
out. Any success anyone with this? What kind of tool should I use for
raking out?

Forget raking out the cracks, I dont know why its so often
recommended. Just wipe a little filler on with a finger, and wipe off.
Done.

The important question is why the existing paint has come off. My first
assumption would be that it, or the paint under it, hadn't bonded to the
plaster. We had a similar problem and took the walls back to the plaster.
