Do I need to PVA newly painted plaster/plasterboard?

[Gazzer]

YOU MUST HAVE DONE IT WRONG:hurray:

Yep....we put PVA on the wall

 

[floydyboy]

I HAVE BEEN TILING FOR 17 YEARS AND WHEN PVA IS REC I WILL USE IT, IT IS WHEN U MIX IT TO THICK U GET THE PROBLEMS. I HAVE NEVER HAD A TILE FALL OFF.

 

[Gazzer]

Just a kid then? You carry on and use it.

Oh and dont shout, i aint that hard of hearing yet.

 

[floydyboy]

sometimes you got to shout
cause some people r so thick :stupid: u need to do your home work :yes: 17 years is enough to advise and by the sound of it i am advising u cause u only know BAL.:lol:

 

[Gazzer]

Actually i rarely use Bal so you need to do your home work and if the years decide who is right or wrong then my 31 years should settle it....but i doubt it....as i say you carry on with the PVA.

 

[floydyboy]

31 YEARS YOU SHOULD KNOW ALMOST EVERYTHING. LIKE I STATEDIN A PAST THREAD ALL ADVICE IS ACCEPTED [IF RIGHT] PLEASE TAKE TIME OUT AND HAVE A LOOK AROUND ALL THE TILE STOCKIST AND NAME THEM. :mad2: I HAVE NAMED THEM AND DONE MY HOMEWORK THERE IS STILL A LARGE NUMBER OF ADHESIVES OUT THERE THAT REC PVA. GO AND LOOK AND PUT THEM ON HERE. [TUNNEL VISION]:hurray:

Ok, so if I score the area to be tiled and then prime with Mapei Primer G or BAL ADP I should be ok?

I really didn't realise you couldn't tile straight on top of emulsion. I kinda feel silly because we painted the walls BEFORE tiling, well, partly.

It seems very odd to me that it's considered OK for plasterers to use PVA prior to skimming a wall, but then a tiler who comes along afterwards and wouldn't use PVA.

Surely the same principle applies?

Surely the same principle applies?[/quote yes it does. when moisture makes contact with pva it becomes active again BUT A BIG BUT the adhesive or plaster dries and so does the PVA giving it the adhesive properties but it only works if mixed correctly. to many people on here r primer mad . follow the recs:hurray:

 

[lukeo]

I ended up buying some BAL primer. I tried to get as much emulsion off as possible, but it was taking too long so I heavily scored it and primed both bare plaster and scored emulsion as directed.

It's amazing the number who tile suppliers who don't stock any kind of primer but sell everything else! I went to 4 shops before I got hold of some.

The fact that hardly anyone stocks it tells me, not many DIYers will be using it!

Neale u r very respect by many on the forum and ur word is religion in my eyes thank u

Simple answer to this is you use Nicobond Unique, no primer required on plaster or plasterboard.

You lot spend so much time in Topps reading Bal bags you dont know whats going on in the world

sorry i did not mean you i meant the forum. it has recomended TOPPS TILES for advise and materials in the past.like i stated i use wat ever the manufacter recomends but mainly sbr but just saying a lot rec PVA .

Some members would have recommended them, some wouldn't. It's a forum. Just like out there in the real world there are different opinions.

You'll get about the same % of the fixers on here supporting various companies just like on-the-job too, so you'll see a lot of Topps mentioned as they're the UK's largest tile store, and a lot of BAL mentioned as over 50% of the pro tilers in the UK use it.

Though we have support and representatives from Mapei, Weber, BAL, Larsen (though haven't posted for some time) and a few randoms like that lass from Johnsons Adhesive.

So please be steady when pointing that finger as one members comments isn't the view of the whole forum.
