The surfaces need to be washed down to remove as much surface contamination as possible. Apply the Alkali Resisting Wall Primer to any stained areas, then use Acrylic Eggshell as the finish.

That way, even if you didn't get complete hide of the underlying white, it would look better than if you didn't get complete hide of the underlying green or blue or brown or other color.

That is, is the surface you're planning to paint already painted, and if so what kind of paint and how glossy is it? And, what kind of paint are you wanting to paint over the emulsion when dry? Priming bare timber is essential for the success of the whole paint system. The primer soaks into the timber creating a good bond and quenches the absorbency.

Oil-based undercoat paints are for use with oil-based finishing paints. While these paints were traditionally the choice of professionals, advances in water-based options mean that today many will use both, or have moved to water-based entirely.

The heavy-bodied paint resins in self-priming paints seal the surface and fill imperfections (which are less visible in flat paint anyway).
