Completely agree that they can raise the grain. But, in that sense
luckily for me, most of my painting is re-decorating where the substrate

I find that water-based paint is fine on wooden door frames and
skirtings, etc. However, what it's *not* fine on is MDF window cills if
they're ever likely to get wet. When the paint is thoroughly dry it will
still let water through - unlike oil-based paint - and this will bring
the MDF up in a nasty rash.

I wouldn't use MDF for window cills again. They all turned into
weetabix, even using oil-based paint.
