HI Folks

I've just been shown a list g of

"Things To Be Done Before the Winter....."

now that the Irish Summer has been & gone & I've finished the open-air
markets for another season).

Some of this list is 'fun stuff' (like adding auto-air-vents to the
central heating, and fixing the soil pipe vent which used to vent into
the roof space (nice!)) - but there are also some jobs which are going
to be simply tedious....

The house has only been lived in for the past 2 years - but I believe
that it was built over an extended period of time. Probably because of
this, and as everything dries out, many of the rooms have cracks around
the join between wall & ceiling - where the ceiling seems to have raised
by a few mm. This is unsightly, and is 'To be Fixed' ....

So - flexible filler (acrylic??) from a mastic gun and what's folks
preferred 'weapon of choice' for getting a nice, smooth, 'doesn't need
sanding' finish to this sort of repair ?

I'm particularly keen to avoid making it worse than it already is g

A similar job needs doing round the inside edges of the UPVC windows -
where a small gap has opened up - same technique / tools ?

Suggestions / techniques etc, please ??

Thanks
Adrian
