Hello!
We have moved into a house where the walls are plasterboard.
They're in reasonably good condition but we have just removed wallpaper and are painting most of the walls (some will be wallpapered).
I prefer to "do it right" first time but also want to make sure I don't over do it.
I plan to use Bullseye 1-2-3 but realise this is fairly pricey stuff compared to normal No-Nonsense undercoat. Should we use Bullseye 1-2-3? There is a couple of Rennie Mackintosh type murals that have been on the wall historically by the looks of it.
In addition, in the room where paint is still on the walls it has a bit of a sheen to it (maybe eggshell?). We're planning on painting this Matt. Do we just use primer/sealer on this too?
