I have 2 sections to my living room, the original section is just dot and dab plasterboard the new section Is solid plaster walls.

I've just removed all the lining paper and dado rail that was installed by the previous owners and there is peeling Paint all over the walls as is expected from old builders coats of paint.

The old section I am going to have a plaster skim as this is just bare plasterboard,

the new section as there are a lot of cracks In The wall and peeling Paint I am planning on just lining again.

I will let the plasterer sort the old bit out. But the new bit i know I need to seal the flaky Paint and the wallpaper paste.

Do I use peelstop or gardz? They both seem to do similar jobs but are different also.

I've recently lost faith in zinsser products, is there any alternative to use?

If you have a plasterer coming in, I'd get the whole thing skimmed . It will look a million times better.
I removed old paper, paint and filled cracks and did some repairs before sanding my living room. Then I sanded all the walls before paint. It took four weeks
 
The plasterer can't guarantee the cracks won't reappear after skimming regardless what he does, so I decided it best for me to lining paper the solid walls. With him doing the old bit wichbis just plasterboard

Why is that?

The product of their's that I am most likely to use in BIN (the shellac based paint) but I am equally happy using the new kid on the block ( Blockaid - made in Scotland).

With regards to the old paste, personally, I just sand it off but if you don't have a random orbital sander and dust extractor you might be better off using a Zinsser product such as Diff or even bog standard washing up liquid and warm water.
 
I've just used the perma white on my stairs and I'm not very happy with it, it's still soft 2 months later, when I masked it up to emulsion the walls the paint came off with masking tape,

I prepped the wood work by giving it a good sand to remove the old peeling water based gloss, in some places it was right back down to bare wood, I then have it 2 coats of bin primer, all being wiped down between coats, just really not impressed.

I then recently bought the tiger paper shredder and the wheels kept siezing, I ended up modifying it to stop this, and I used there dif wallpaper stripper, and to be honest just plain warm water worked just as well.

So after all that I've lost faith somewhat, however everyone seems to be recommending their gardz and peelstop, but likewise there doesn't appear to be any alternative either.

I'm sanding the walls down the weekend, and washing them down so will make a decision after this

Fair enough, thanks for the clarification.

I am not an apologist for them, as I said earlier, the product that I am most likely to use is BIN. That said, I have seen people use BIN as a "cure all primer", it ain't. If the substrate is "weak", it and the BIN (plus anything applied over it) will come off.

On reflection, yes I agree that Zinsser have a history of over inflating the qualities of their paints. BIN is a mare to apply to wood work whilst maintaining a good quality of finish. And using it is not a substitute for sanding the previous finish.

I recently painted MDF units in a house where the decorators blitzed all of the woodwork with BIN (using mini rollers and kinda laying it off with a brush), every single door that they painted had chips of paint missing by the time I started the job. Once the client saw the finish on my hand painted units he understood the difference in quality of finish.

He has asked me to paint the next house that he buys.

That said, if I roll a wall and find waterstains bleeding through, I will turn to BIN or Blockaid.
