We fairly recently painted our hall and stairs with a white satin
finish, not sure now of the make, but have been disappointed because
it's remained slightly sticky to the touch and has to be sorted out.

So what to use. It still appear that solvent based paint yellows, whilst
water-based paints require several coats to cover. Some of the reviews
are dire.

So all I want is good coverage paint that will be hard-wearing and
remain white for as long as possible. It will require a
primer/undercoat, because in places, removing the sticky stuff has
exposed the wood. So any recommendations, as to a reliable brand ?

TIA
