Plastering chased out walls

I've just done exactly what you are going to do. The difference being with mine is that I cut some plasterboard to fill the gap, screwed it to the studs and then plastered over the top. The only thing left for me now is the sanding and painting, and I am finding the sanding the hardest part, trying to get it all smooth and level.
 
Colossal fudge up at the start whereby my mix wasn't to right consistentcy so started dropping off the wall with ease lol. Walked away in frustration for 5 and had some crisps. Came back, recitified the mistake, the Mrs came back in and looked much happier with it haha!

Finishing coat tomorrow. I'll see how it goes and make a judgment call on how good/bad I can get it as to whether I bite the bullet and get someone in.

Glad I've given it a go though. You don't learn by not trying!

So after all the advice you aren't going to bother telling people what option you chose? ;)

For what it's worth now, looking at that photo I would have used a couple of applications of Gyproc Easifill 60 and sanded it flat using a wide hand sander so it was flush with the wall. Easifill is brilliant stuff.

Probably worth a diluted PVA coat too, as plaster doesn't like breeze block. I tried putting bonding plaster straight onto breeze blocks last year and it failed to adhere spectacularly.
 
If your using plaster. A trick to get a very smooth finish, is to make the mix a consistency of tooth paste. You have to use an electric wisk, secondly when the plaster is starting to dry and firm up. Around about 25 mins after you have applied it. Get a spray bottle of water and soak the plaster and push very hard on it whilst smoothing it over. It will push air out of the plaster and leave you with a smooth finish.
Do it once or twice and then wait ten mins, rinse and repeat until its like glass

don't over do it like that, used to work with a plasterer who would spend to long polishing the plaster up. decoraters where always moaning about it and sometimes had to give it a light sand.

also you don't have to use an eletric whisk, small amounts i just use a trowel or stick, just takes a bit longer to mix properly. when i first started there wasn't mixing drills and we had a bicycle chainring welded to a handle to mix with, that was hard work to do a full bucket.

You actually don't want it like glass as the paint will flake off.
