"You'll need PVA for that"

[Ajax123]

I have had 7 calls this week, 2 of them today and it is only Wednesday from people who have either bought and already installed or bought and are awaiting installation of tiles. They have all bought their tiles from what I would consider reputable tile outlets and are spread throughout eastern england. All of them have been told by the outlets that they should be using PVA as their primer. :mad2:

Could we all undertake, whenever we go into any tile shop or warehouse, to say to the staff that PVA is not suitable as a primer for tiling

Pleeeeeeaaaaaseee!!!

:banVA :banVA

There was a young from Nantucket
Who bought PVA in a bucket
His new shiny tiles
Failed after a while
and all he could say was "oh flip ...... I promised not to swear in the forums but this is a right mess and is going to cost me a fortune"

It is really good for sticking glitter to works of art by kindergarden kids though:lol:

Surely these tile shops must stock proper primers and you would think it would be in their interest to sell these to customers and not give them duff advice like use PVA

you'd think so but it never seems to go back to them so maybe they are just selling the cheapest rubbish they can get.......maybe it is just they don't know.....

I agree with that Al, i assume it is just down to a lack of knowledge rather than a product stocking issue - but these places should be speaking to there adhesive manufacturers and going to trade days like what Mapei haveand learning.....

it's down to a lot of the old timers insisting that "unibond is right stuff to use"!! I've managed to sway a couple of independent outlets by showing them the pva v primer thread

:incazzato:Trouble I have of course is that the screed is usually the first thing to get blamed for problems. :incazzato:

My beef is with these so called experts, some tilers still insist on PVA. But imo the worst culprits are, the tile shops who stock for eg. Mapei/ PCI ,Biscem etc. adhesives. But don't stock the relevent primers:yikes: they are not all compatable:ban:

 

[doug boardley]

you'd think that there'd be a universal primer that would allow ettringite formation to occur between cement addy and gypsum substrate though.
