Prepare for painting with sugar soap or fine sandpaper?
 

I want to use white gloss to paint some white doors inside the house.

The doors were painted with white about 15 years old and are getting
discoloured.

I know preparation is important but in this case I have to compromise!

I'll use white undercoat and one topcoat of gloss. The undercoat is to
even out the surface and prevent discoloured patches showing through.

QUESTION: If I can use either sugar soap or fine sandpaper to prepare
the surface (plus filler for holes) then is it better to use fine
sandpaper than sugar soap?

Even a five minute rub down with fine sandpaper makes a big difference.
Use as much undercoat as you need to hide the imperfections, then one
thin coat of gloss

I've always had good results using sugar soap and giving the paintwork
a good scrub with the rough side of one of those pan scouring sponges.
Then a final wipe over with white spirit. The only mistake I've made
is thinking I could get away without the undercoat, looks great when
done but starts yellowing in a matter of weeks

I was also thinking along these lines having a similar job to do.
So I've decided to try some of that wet 'n' dry sandpaper using a sanding
block
and a bucket of sugar soap solution in one go, seems to work OK
but I also wiped down with some old rag immediately, this seems to help get
rid
of the dirt. It takes a while though, I don;t think it'll be safe using an
electric
sander with sugar soap. :)

That's a false dilemma. You use both, if you care.

If forced (especially anywhere near a kitchen), I'd go with the sugar
soap alone. Unless you've already washed down and degreased the paint,
sandpaper used alone will clog before it achieves much. I wouldn't
even use sandpaper - this is definitely a job for an open mesh
abrasive, such as wire wool or a plastic mesh Webrax/3M if it isn't
too bad.
