Advice - Coving Falling Down

Hi Guys,

Just wanted to seek some advice.

Ive just had, at considerable expense, coving to each room done in my home. 11 rooms.

I was initially pleased, but was concerned when a couple of days after the first few rooms had been done, 1 piece started sagging and eventually fell.

Then a day or two later, in another room, I found 3 (adjoining) pieces on the floor, and as I was looking, 2 further pieces came off in my hand.

Then on the same day another three pieces (again adjoining pieces) came off in another room.

The plasterer is a knowledgeable guy who has done good plastering work for us before and was extremely apologetic and confused. And has replaced the pieces.
Its been a couple of days and nothing else has come down, but I am concerned, if it was to fall down on a child, it could be extremely dangerous.

I know very little about plastering but he used some sort of unbind adhesive to use as a "key" so that the plaster would grip the wall.

I just wanted to get some thoughts, because i'm worried about other pieces falling. If it stays up for a week or so, is it safe to assume that it has gripped and will be up for good?

I've had to delay painting and wallpapering due to the issue, and am just unsure what to do!!
 
@Fibrehand should be your man.

I have seen big cornices have screws countersunk and filled to hold them in place.
Maybe the surface was dusty
Not primed?

As said some covers on here can maybe shed some light

If you want price of mind you could use gripper dry wall screws then fill the screw heads.
Just a few in the full lengths would stop them crashing down.
Also save taking the lot down.
 
Probably put it up with bonding compound to save a few pennies what I would suggest is go around the whole lot with a white liquid nails and use as silicone.
 
If its falling down he simply hasn't done it right. I would be concerned about the rest. Where are you based? Chances are he's used as said dry wall adhesive which doesn't work and no screws.
 
Why doesn't drywall adhesive work? Ive seen 100s of lengths go up with it and stick like **** to a blanket
 
Was the surface bare plaster? If it was painted it should have been scored with a stanley knife. If it was bare plaster he may have used a strong mix of uni bond which would create a film rather than kill a bit of suction

It dries out far to quick. Imagine plastering over year old bonding it would just tear when trowling up.

When you put dry wall on cornice it does the same. You l have to pva it to ****.
Done it
tried it
Wouldn't trust it

Just to two cents.
 
So bonding compound will hold a 15mm 8x4 fireline board but won't hold a 3m length of paper Bound coving? Cant see it myself mike.
 
I use waterproof tile adhesive to stick it up, strike 2 chalk line 3 3/4 from the angle into ceiling and down wall and Stanley knife/score the inside of the lines.

bang a few nails in while its up to hold it in place while adhesive takes, then go round with easy fill and a small tool and a bucket of boiling hot water fill and clean of as I go round.

i also use to cut free hand, as the guy who taught me told me mitre boxes were only good for bang square rooms which is rare on domestics, fu kin 8 ft baton cutting coving ceiling side down.

not now though, I'm a rough c**t.

touch wood, none has ever fell down
 
I use dry-wall with Gyproc no problems at all, old walls I'll score brush on some dilute PVA to soak in. BG Dry-wall is crap btw, too claggy - our merchents stock the G-Tech stuff and it works well as a cove adhesive.

Mind you we re-plastered a room once that had been coved maybe 20 years ago and the old coving fell off when you looked at it - no idea how it stayed up so long. Other times when removing old coving they must have used araldite.. (seen lots of stuff used that's been a bugger to remove, skimming, tile adhesive etc. so it shows it works when done properly).

Practice, I do it on non-square angle. Hold cove up to ceiling and run a pencil along the edges on the ceiling then mark the cove where the lines intersect.
 
Been a while but, measure the distance form corner to corner then to the struck chalk lines on the ceiling, mark the bottom of the cove, use a square to find same point on top of cove then measure (I think) 3 3/8th give or take.

mark that point and cut ceiling side down from the bottom of cove to the top/ceiling side, I used to do it a lot and to be honest my cuts were better than they are now with a mitre box, I can't seem to get on with them, but going back to the old way would probably cost me 5/6 lengths of cove in fu ck ups.

it was good and fast once you got into it.
 
Was always taught to sand cut edges down before putting it up.

i was made to take some down that had been filled and cleaned because there was microscopic bits of paper from the cut on a piece I hadn't rubbed.

my old gaffer was proper old school, I got the fu cker back when I poured boiling kettle on his hand :RpS_lol:
