Prep before skimming

[NickB_99]

Got a couple of options here in skimming a bedroom and thought I'd ask for some advice.

When stripping the wallpaper the skim blew in a few places. I don't think it was helped by being very thin in some areas (1mm or less).

Anyway, I've now covered in WBA (the key on the emulsion didn't feel good) and ready to skim.

My question is whether it's worth levelling out the missing areas to bring up to level of surrounding skim first?

Could use either bonding or multi finish to bring level or just skim the lot with multi from the start.
I'm wondering if I do the latter, as these missing areas could be quite thick that it either slumps or is difficult to get flat as the different thickness may set slower?

I'd fill up the deeper areas with bonding first NickB, for the reason you said, to avoid slumping. All ready to go then with the multi. I also let the deeper areas of bonding set first, and then skim.

Thanks r/c. You confirmed my suspicion and will give a better result.
And I guess by skimming just after the thin layer of bonding has set, it won't need any suction control reapplying.

It's strange. All the steam stripping I did in my last place never blew any plaster. In this house, first room and it blew in lots of places. It seemed on solid, no hollow bits sounding before stripping. It was painted wood chip and didn't come off easily - maybe that contributed.
