Hi,

We have a few cracks in the upstairs ceilings and as we decorating a
room at a time I would like to find something that can be used to fill
the cracks and if flexible so it wont crack in future, the bedroom we
doing at present needed the old paint scraping off and I've skimmed it
with plaster but there are cracks along the joints of the boards, there
may be some movement in the joists above but fixing that is way beyond
me, so does any one know of a good flexible filler that works ? These
are hairline cracks by the way.

TIA,

Mart.
