After having ground floor ceilings re-plastered for a second time, they
are once more showing cracks. I assume the joists are moving and
causing this to happen. The floors above the ceiling are extremely
noisy when anyone is upstairs.
Does anyone have any suggestions on how to replace the ceilings as
re-plastering is very expensive and obviously not the answer.

Having "ground ceilings" is something only found on that tiny island
national of england, home of Robin Hood and his fairy men.

I've got a couple of board joint cracks too - get used to it is my advice.
Plaster is hard and unforgiving and buildings (especially ceilings) move a
bit, especially over the seasons due to heating as well as the shock load
from above.

I'm going to smear a bit of caulk in mine and just run a strip of fresh
paint over (they've not long been painted).

For micro hairline cracks, I've peviously painted some PVA on and painted
over - seems to work in that it sticks the edges a bit and discourages tiny
movements.

Don't really notice them anyway.


Cheers

How old is your house Archie?
I suspect that most modern houses will suffer in this way.
The push towards cheap construction means that lighter beams of poorer
quality timber are used these days.
Calculations are produced to support the use of these beams and prove that
they will not fail. But they will be designed closer to the allowable
deflection than would have happened years ago. Plaster is an unforgiving
brittle coating, so as the plasterboard ceiling tries to flex, there can
only be one outcome.
Also, the lighter beams do not deaden the vibrations/sound as well as their
more substantial predecessors.
If your house is not of modern construction, then I would suspect that some
settlement has occurred to allow some movement of first floor joists. This
would not have to be serious structural stuff, just shrinkage of key timbers
would be enough to crack an expanse of plaster.

Phil,
The house was built around the mid sixties, it's really annoying to have
had the plasterers in and then find the same thing happening once again.

I'd really like to get this sorted but I'm at a loss as to what to do
about it.

She who must be obeyed has said it must be fixed!!
Anyone any Ideas how to deal with this.
The ceiling I mean, not the wife!

Thanks again.

I can't think of any quick and easy solution, other than caulking and
decorating over the cracks.

Do you have any idea what size the ceiling joists are, and what do
they span?

How much of a job to take up the first floor boarding? Adding
additional noggings between the ceiling joists might beef it up, and
you could also insert some sound insulation.

I meant to add, if you are looking at replacing the ceilings anyway,
you could do the beefing up and the insulating from underneath.

Or get a big oak beam and fix it under the joists at mid span,
supported in the wall at each end. Horse brasses optional.

If the cracks are very long it's likely that they are the joints
between the plaster boards. These should have had scrim applied to
them when they were plastered. (It's a roll of stuff that looks like
loose weave bandage.) Made out of glass fibres these days. You can
reskim the cieling putting some in or you can grind a track out along
the cracks about three inches wide with a belt sander and put some
in. You will need to use unibond in the plaster to get it to stick.
Messy job.

You want to try my homebrew chilli oil - two pots of dried crushed chillis,
cooked in just enough oil to wet it and a handfull of black peppercorns to
spice it up a bit.

Still doesn't blow my face off (though Mr Colon has a few words to say) -
might need to start ordering some of Blair's special sauces soon - there is
now nothing in the shops that I cannot consume with ease. I feel an order
for some "MegaDeath" coming on. At least there's an upgrade path terminating
at "Special Reserve 3am".

You dont give us enough info to know whats causing the cracks. It
could be hairline cracking between boards, structural movement,
disintegrating lime plaster, or timber frame construction that moves,
undersize joists, or pretty much anything. Without said info, how can
we know the solution. Papering over them, regardlses of the actual
material used, is unlikely to stop it happening again.

Often ceiling cracks are overrated, its very easy to run a finger of
filler along them at painting time.

Sorry,
I really don't know anything about the fabrication other than that the
internal walls on the upper floor are built on top of the flooring,
which is chipboard. The noises are the boards squeaking when anyone is
moving about upstairs.
The ground floor has a composite base, there is no sign of external
wall movement or sinking.

Having lived here for just under twenty years, I'm sure the main house
structure is sound. It's just annoying, having to try to mend the
ceilings when they have been plastered twice before already!

Thanks for all reply's

Taking up a single board in the right place, glueing in herringbone
strutting, and anchoring the end joists to the walls will stiffen up the
ceiling considerably, possibly enough to stop the cracking.

It is easier to fit strutting tight across the gaps between joists than it is
to fit tight noggins.

It helps to stick new plaster to old especially where you want to
feather the edges out.
