I picked a nice Ivory coloured emulsion for my living room. I recently
stripped all the wallpaper off it, but when the emulsion dries it dries a
lot darker that what it should.
I used the same emulsion in my spare bedroom and it dries to the colour it
should be, but the living room colour is darker.
The spare bedroom has lining paper whilst the living room has bare walls.
Does the living room walls need for sort of undercoat, if so what ones would
you recommend. I did go over the walls with white emulsion to lighten them.
