Yes, I'm only just past 'novice tiler' stage but already I've met a few tilers 'who have always PVA and always will, cos it's never been a problem.'

Re: P.v.a. Versus Primers......
The really big question is - how many of those tiles are still up and still fine? Have you actually had to go back to any of those jobs, to repair them? Perhaps the tiles have all fallen off and the people simply haven't told you, they've just slagged you off to others!
Who knows. I have no doubt that the arguments against PVA are all totally true - however, it does make one wonder, that at the end of the day many many people were using PVA for a long long time before this widespread knowledge of its poor abilities came to light. One would have thought that if it really was so bad - then the problems would have been spotted immediately and it word would have spread like wildfire about it. But it simply didn't (did it?). I'm not sure how long PVA has been used or how long primers have been about, but it does seem strange to me that from my poor knowledge of it, PVA was used for a long time.
In no way am I recommending using it - just commenting on what I see.

Re: P.v.a. Versus Primers......
I've just had my bathroom plastered, let it dry for a couple of weeks, and then went over it last week with a weak (7-1) coat of Evostick waterproof PVA. I've spent all week painting it!
I don't intend tiling all of it, just around the bath, so will it be ok just to sand the relevant area down before tiling, to try to remove the PVA, or is some other prep required?
Cheers!

Re: P.v.a. Versus Primers......
here's a question for you all...
I've removed a laminate floor at my house as it was always spreading at a certain joint and im sick of "jump & sliding" it back together. Dont tell me you dont know the jump and slide "move" cos i know you do!!
anyway, the reason it kept popping at that certain part was down to the gargantuan drop the bitchumen/ashphalt floor suffers at that point. I intended to self level and tile, but after ringing BAL technical this afternoon to find out the best primer (not PVA) to use on Bitchumen, only to be told they dont recommend doing anything with bitchumen other than removing it completely.
Removal is not an option as this was poured in and floated in when i bought the house (built circu 1927) to act as a damp proof barrier. Its not a thin layer originally used to fix vinyl tiles etc, im sure you will all know what i mean?
So whats my options here? I've been and bought BAL Bond but im at pains to just go ahead and use it without asking first. I intend to tile the floor in the end by the way.

I'd be tempted to put a 1:2 SBR /water down as a primer and then use a flexible slc
