Scrim tape loose filler on top

Question

A painter came in and covered a ceiling crack using scrim tape with some plaster/filler. Taken off the top layer and while the tape looks stuck to the ceiling the top layer seems to be loose. Any suggestions what went wrong and how to fix it?

The old plaster needs cut away, the width of the scrim at least, then apply scrim, ideally use finish plaster on to scrim, and blend in with original plaster, or apply at least 2 coats of filler, leaving each coat to a while before applying next coat

Ben · Answer

He probably didn't pva prime it, so it might have dried out too quick and de-laminated.

Scott · Answer

Maybe you should PVA the area let it dry and fill it again

Garry · Answer

Cut the tape off take off loose filler,  sbr  which is better than   PVA , let it go tacky, then fill again  with good filler, a  picture would be helpful

Agree with gb plastering. However it would be best to get your plasterer to redo this, it won't cost a lot and will look so much better, then I expect your painter will be happy to repaint it for you.

Gregory · Answer

If he used plaster then he might not of used PVA glue to seal the surface and created a key for the material to adhere to. To fix it scrape all the loose material back PVA and then refill it.

Take old tape off, tidy up area.  Prepare with couple of coats Unibond PCA then skim over and feather in.

Stephen · Answer

It sounds as if the painter didn’t apply PVA on it therefore it will come back off again.

Hi, 
The painter should have sealed the area where the crack is with a PVA solution and allowed it to become tacky after applying the scrim then covered the scrim with easy fill or similar filler.
I suspect this was not done and as so the filled is now coming away from the painted ceiling.

Rick · Answer

It wasn't done correctly. If you put scrim over a crack and then cover it with filler you are doing a repair that is proud of the original surface. like dry lining joints which are inferior to plastering and visible to the eye a lot of the time not to mention creating a different texture that can show up when painted. hence the need for plasterboard priming but if you do all that you may just as well have it plastered leaving a smooth even texture that paints covers evenly. It would not matter if the ceiling had been completely skimmed the plaster would be flush over the scrim tape to the surrounding area. If both sides of the crack had been recessed for the scrim tape to sit then the filler could have been sanded back flush but this is a lot of work and not guaranteed to work. Once a crack is there they often seem to come back. If there is any movement in the joist/plasterboard it will come back. A hanging plasterboard edge (not screwed into a joist, butted up to another board) showing a crack is best drilled at intervals and then injected through the holes with plasterboard adhesive (sets rock hard) the crack then v grooved and filled/sanded.

A simple flexible sealant would have been sufficient
