Sugar soap or sandpaper for interior door ?
 

I want to paint some interior doors and skirting boards. They were
last painted about 15 years ago and are doors to a bathroom and to an
airing cupboard. Apart from looking jaded the painted surface is not
damaged.

I'll probably use one coat of oil-based undercoat and one coat of
non-drip gloss topcoat.

I don't want to go for an award winning job! But at the same time I
don't want to cut corners unwisely.


QUESTION 1: For preparation can I just sand these down with a fine
glasspaper? Or do I need to also use sugar soap? If so then would
the sugar soap be applied before or after the glasspapering?


QUESTION 2: Is it worth using any special bathroom paint? The
ordinary gloss paint used before is not mould stained or anything
like that but it would be nice if the whiteness could be retained for
as long as possible.

Wash off as you say, then a light rub with fine glass paper to
de-nib.

It's not worth using any special bathroom paint.

Whilst it is not specifically bathroom paint, I have used water based paint
in our bathroom as it tends to yellow less.
For a reason I am not clear on, oil based paints seem to yellow in low light
situations (which many bathrooms seem to be).

Be warned, water based paint is not as easy to use/tends to show up brush
strokes more than the alternatives.

It's also not very glossy (although it has a sheen) and is not
very tough.

Cue loads of people saying how great this sht is. I have used
it in lets, but would not use it at home.

It also has much poorer adhesion than oil based gloss, so surface prep.
becomes much more important. (Also much lower gloss, almost silk
finish, ime.)

It also shows up grubby hand prints when you frequently shut&open the door.
