Hairline crack

I have a couple of fine cracks in the skim of my kitchen from when it was
extended. (skim on Plasterboard)
Just wondering what to do before redecorating (emulsion). Do I need to rake
them out a bit to use a filler - or is there something really thin - like
PVA that will prevent the crack from showing again?

Rake it out and use decorator's caulk, which is flexible. You may need to
fill it a few times as it shrinks as it dries. But should last well when
done. Everything else I've tried seems to just crack again.

As Dave says, rake out and fill. I've not had problems using ordinary
powder filler. Wet the raked out crack before applying a fairly stiff
mix of filler. Wait a bit until the filler is getting quite firm,
dampen and polish like one would plaster. Leave to set/dry then wipe
down with a damp cloth, saves all that messy sanding down.

Everything else I've tried seems to just crack again.

Thats indicates things are moving very slighly relative to each
other. I'd use decorators caulk between wall and arcitraves/skirting
as the timber will move either from vibration from the door and/or
variations in humidty.

Assuming it is a crack on the skim between two sheets, it's safe to assume
it's moving. And will move again.

Ordinary filler is fine where there is zero movement.

I don't think it is moving - initial shrinkage I think.

Then use any old filler. Only time will tell.
