Wouldn't even attempt it without one. I removed all the lining paper
from my downstairs, ceilings included and this was one hell of a job. I
also had to get most walls skimmed again due to the horrors it was
covering up. The little ones you can buy from BandQ are not bad either
and as others have said score first. Oh and buy one of those super
scrapers the ones with razor blades in but be careful you dont damage
the wall with it or accidently slip and injure the Mrs however tempting
it may be, they work great.
