plastering ceiling

hi, in my kitcken i had an artex ceiling which i wanted flat. i removed the high spots on the artex and sealed with pva. the ceiling was very uneven so i used thistel bonding (after applying pva) to level it, keyed it and left it to try as i was too busy to skim straight after.

the plaster has bonded very well to the ceiling but now nearly a week on i am wondering before i skim with multifinish should i seal the undercoat with pva. then skim over a tacky pva solution?

should i not seal the undercoat and just skim over tacky pva? its quite a large ceilng how long will the pva stay tacky for?

ive quite new to plastering so any advice would be great! i really dont want the skim coat to fall off.

Yes, because you allowed the bonding coat to set and dry. It's effectively a new reskim. If the bonding coat surface is rough throughout so there's a good key, then just a sealing coat might be OK.

Even when it no longer feels tacky, wet plaster will make it tacky again for quite a while before the PVA sets solid.
