Weber PVA!?!

[beanz]

Isn't the Weber Tiling Solutions guide supposed to be the bible? I'm not sure what to make of this!?!

Well what can i say..PVA eh!!...have not used it so cannot comment.

 

[beanz]

Seems a bit strange to me, but there's no info on ingredients!?! It's hard to tell people that PVA shouldn't be used, when tile adhesive manufacturers are selling it!?! :mad2:

Its no wonder people get confused about PVA. Its been around so long its almost a household product.

Amount of times i have been priming a wall or floor and the customer say's that's a funny coloured pva..didn't know it came in blue....:lol primer G)..

 

[White Room]

Really surprised adhesive companys are still pushing pva

 

[beanz]

I keep wondering if they are actually selling PVA, or if they are just using the name PVA as it's recogniseable!?! Or are we all being mislead by other manufacturers, forcing us to spend more money on primers that aren't actually necessary? This tiling lark is an absolute mine field! :dizzy2:

Negative good buddy - it is indeed PVA - Poly Vinyl Acetate.....
breaks down in presence of alkalis e.g. cement, gypsum (plaster) concrete, screed etc.

Perhaps in some cases you can use PVA, but not as a primer replacement. Therefore their products don't affect the PVA, and you don't get the issues we all know you can when you're replacing a primer with PVA.

Has anybody ever questions any of these firms to get a formal reply?
