New plaster query

[MattSavage]

Recently had my living room skimmed over plasterboard after removing old wallpaper. Last night I noticed some lumps in the wall that aren't usually visible in direct light, only when I catch it on an angle. I'm not sure whether it's a plaster problem or a paint problem, all the work was done by a contracted plasterer and separate decorator. It seems to have raised lumps(tried to get the best pics I could), I'm leaning towards it being a paint problem but maybe you can help...cheers.

When you press the lumps are they soft like theres air behind it or like a blister for example?? If so its paint thats a problem if firm it could be plaster but if itsonly visible when light hits it in a certain way?? I wouldnt worry. Most re skims by any plasterer under a certain light would show something or another as you are only going over the origionall walls/ceilings etc

Looks like paint not taking , how long did painter wait after walls were skimmed?
You will get all sorts of views when looking at a flat wall with strong side sunlight but nothing like that.
As Marshy says , if its like a blister then there is an issue with the paint, get the guy back and he will fix it for you

I agree with marshy, that said the bumps do look fierce, and for them to be picked up in a photo to that degree I would hazard a guess and say plasterer problem, but like marshy says u will always see something in shallow light

Now i looked again it could be that new unifinish
if its not the paint then it hasnt been unibonded right and is blowing off
Take the biggest lump and press really hard into it and see what happens , if it crumbles call the plasterer and make his day
As bad as some plasterers are it be near impossible to leave bumps like that , its either paint or plaster not taking.
Both can be easily fixed and its highly unlikely it going to get worse as its dried out now

What kind of state was the plasterboard in after the paper was stripped?
Looks to me like its bits of the loose plasterboard paper bubbling up when skimmed?????

 

[superspread]

Yea I only looked at first pic the other 2 look like the papers blown

 

[Marshy]

What pics???

The walls were left for 6/7 days after skimming, decorator said the plaster was dry therefore went ahead and started painting. He used watered down paint for a couple coats then applied a top coat.

I did notice some areas on the plasterboard were slightly damaged when the wallpaper had being stripped (i.e. slight fibre showing) but the plasterer never mentioned any issue.

I'll give them a hard poke tonight to see if they break but they don't seem to have done when general poking around, will feedback.

What's the rectification if the papers blown? Bit worried.

cheers

Its no real disaster, if the papers blown and there's air trapped cut round the edge with a sharp stanley knife peel the affected area off.
coat of pva to kill any suction off and fill with gyproc easi fill a light sand down then repaint.

Managed to give the lumps a good prod last night, the smaller ones near the bottom of the wall seem to break, indicating paint me the problem but the bigger ones in the wall don't seem to be budging.

That looks terrible...I wouldn't be too concerned about the airpockets if the finish is that sort of quality, paint job doesn't make things better either

exactly that

I hate watching plasterers skim over blown pboard as it always blisters and is just lazy... if it is that its an easy fix
