Plastering hole over thermalite bricks

Hey folks,
The gas man came and removed 6 (!!!) gas fires from around the house and
patched over the holes in the chimney breast or outside wall with
thermalite brick.
I'd now like to try my hand at repairing these holes and would like some
advice.
I plan to use easifill for the top coat and sand back where necessary.
Should I use bonding plaster or cut out various shapes in plasterboard
and fill edges for the base layer?
Do I need to bond the thermalite with PVA?
THe plaster around at least one fire is falling away, so it'd be easy to
remove a large rectangular section of plaster and dot and dab a piece of
plasterboard.
The walls are fairly rough as is and in need of a re-skim. I was hoping
that if I can do this work to decent standard, I could skim the room
with easifill. If it turns out that it's much harder than I imagine it
to be, I'll call a plasterer, haha
Thanks in advance.

You should use a type of plaster called "hardwall" for the undercoat. The

water suckage of thermalite blocks dries normal bonding before it has tile
to set properly, leaving it very powdery. At least that is what I saw when I
tried a bit.
I do not believe PVA is necessary.

small areas. Doing a whole wall with it is much easier, but you
do need to learn how to do it - it's not intuitive.

Or wet the thermalite blocks first (not too much), and use bonding coat.

You want to paint the existing plaster edges you will be bonding to
with dilute PVA, and it will do no harm on the thermalite too.
If the plaster around is loose, you can try and pour dilute PVA
down the crack behind it to stick it back. If you keep knocking off
the loose plaster around the edge, you'll probably find you never
stop.

Regular finish coat plaster is not easy to use as a filler for

I am going to start off with the hardwall and see where I get with it. A

plasterer came round today to quote on replastering the entire house and
said it would be bad to tackle the plastering myself, so I'm going to
try tackling some non essential areas such as to see if I can make it
look half decent.
