Looking at this picture the answer to your question is no. Yes there are other reasons why it can happen bit again from your picture lack of adaquate key appears to be the problem. NEXT

They have used the soft comb , probably Refina, for the key , which in this case is useless . Not the comb , the way it's done. If not blue grit , try sbr/sand/cement -1/1/1 . Wet the wall before applying the sbr and don't wait to dry completely. It will provide everything you need for the skim .

It's definitely had a gypsum float coat on top of the s&c
it does look like the first coat of 'set' is a different colour. the op said it is 3 to 4mm thick. could well have had a coat of bonding.

Hi mate why don't it like like S&C - no lime in mix I asked
No mate done through a firm found them on ratedpeople - does it look that amateurish? Can I ask why it looks so bad I know it might be a silly question but I don't know and would like to at least know what I'm talking about when they come back

Ah ok mate - it's just they said hack off skim and blue grit I just want to be sure that's right
I was actually up there chatting to them when they were applying the skim in that room (they like to talk) and definitely no bonding it was just 2 coats of multi finish
I'm not sure whether to tell them I'll just get someone else to do it but I know people don't like finishing other people's work!!!

I've enlarged the photo you posted here for clarity - the top section is the ceiling (darker shade of white) and the lower section is the wall - did you paint it in a trendy 'bumpy' paint or is that the finish the artisan spreads left?
Also, can you remove a piece of skim from the S&C and post a photo of the back of it....and make it quick as I have a baked spud in the oven and I'm hank!

I'm going for tuna mixed with sweet corn and a bit of mayo to bind it all together. Beans & cheese is an excellent suggestion opo

Did they say why they chose to use sand and cement?
Taking all the skim off definitely on that wall and I will speak to them about the other S&C walls as they have a few cracks as well so if the skim comes off easy then I would like them redone
All the walls that were baten and boarded are perfect
hi mate that's the pixilation of th camera the walls are smooth and that's just a mist coat on the walls - the ceiling is not in my original pic that's the crop line where you have zoomed in
I have attached 2 pics of the skim hacked off the wall hope they help and thanks for your time

Said that's what they would use in their own house and will last

Okay, this helps with the diagnosis. So in the first photo it does look like it was just finished in skim (with no Bonding/Hardwall before the skim). The back of the skim does have a slight indent where the skim has been pressed into the S&C key (but, the key was still not good enough). If the floating coat is not consolidated with a devil float correctly the skim will not 'bond' together and any decent experienced spread would now this. The S&C coat doesn't look to have been straightened/ruled off to a decent floating coat finish. The sand & cement looks to be a 'builders sand' or similar sand....crap IMO for plastering.
When you scratch your finger nail over the skim finish does it seem powdery? Or is it tough/strong?

i dont know anything here but il give it a bash......a waterproof scratch on the middle floor of your house floated with hardwall next day then skimmed the same day.
they dont know how to use hardwall .never mind sand and cement (which is basic plastering)
they couldnt straighten it right or get it flat thats why theres a huge donkey coat of skim.
its a fuuck up.
show them this message.

looks to me they have scratched that with a tiling trowel and held at the wrong angle. What ive always done and im sure yous have too is to gt your float, small thin nails, knock them through a small amount and scratch the wall like this after the sand and cement has took up abit.

i can see s&c when i zoom in spots of it.
mesh was because its an old property and timber beams where used before we used concrete/steel lintels...and the brick work is old and shiit.
the top of walls i bet where timber part of the roof
sand and cement is the strongest but no need for water proof.
you needed a brick layer to tie your bricks back to both skins.
a skim of s&c with waterproof set with hardwall and a donkey coat of skim isnt gonna work.
im not the best spread in the world but im not a chancer either.
to fix it your gonna struggle stripping it all back.....on old brick without more damage
take off the skim gypbond 24 hours then skim
i cant think of anything else.
