Small plastering jobs

danrv

Hi
I’m having real trouble getting a plasterer to do my bathroom. I can’t do that myself but in a couple of other rooms, the plaster has bowed   
out from the wall in one area.
There’s a vertical line with an edge that sounds hollow when tapped (pic).
Otherwise the plaster’s ok for repainting.

Just wondering if a section like this can be done DIY rather than keep getting plasterers in. I’m ok with most other jobs.
Any help appreciated.

A small patch is quite easy to DIY.

Thanks. Good chance to practise too.

You won't know how 'small' it is until you expose it.

Are you speaking from experience where you think it's a couple of bubbles and ended up hacking the whole room off?

Yes, easily done.
This is the largest bit I need to do.
On the left, the wallpaper pulls away but leaves
a backing. 
I have a wallpaper remover/steamer that I could try.

Thanks for the replies.
That's quite a large job that wall and I'll need to tackle that seperately.

I keep coming across small popping patches in walls. Bit annoying when the rest of the wall is fine.
Just doing my downstairs loo and some plaster has come away low on the wall.
About 8x6" gap that I need to fill. The grey wall material underneath is a bit loose aswell.
Any suggestions of filler would be appreciated. I do have cement, sand, hydrated lime and a tub of interior Pollyfilla.

Back when your house was built the plumbers used to wreck walls (especially block) with a lump hammer and chisel to cut out holes for their pipes. At least nowadays they normally use a core drill. Get some sand/cement into the joints after damping them down. 
I'd use some sand/lime/cement for the scratch and float coat and then a skim of plaster.

That explains loose bits in walls. Bathroom the same with patches of sand/cement mix.
The plaster is the slight problem. Sounds simple enough job but I don’t really want to buy a large bag.
Already doing that with the repointing materials and a bit short on space.

Maybe a thin coat of Pollyfilla or get a small tub of ready mix plaster? It’s quite a small area.

You can get small bags of patching plaster, but they are not much cheaper than a 25kg bag. If you have some fine sand you could mix a 1/1 sand/lime and use that as the setting coat.

I thought you'd got a plasterer coming today? He might rattle it off with some bonding and skim?
