    Ok you've totally missed the point of the post.

    BAL SBR,is based on PVA, it's a slurry primer it is fundamentally PVA with water based polymers added which alter the liquid so much that they are no longer PVA and are renamed as a result to SBR.

    There is a product made called PVA External, it is wood glue for use outside which is water resistant, it is not waterproof and neither does it provide a waterproof barrier.

    If the product wickes are selling is a Polymer modified PVA they shouldn't be calling it anything with PVA in the name, it's misleading, people will assume that any form of PVA can be used as a waterproof primer.

    It should be renamed to whatever it's been altered to, an SBR for instance.

    My point all the way through this is, PVA is not waterproof until it's modified with polymer additives, when it's modified it's no longer PVA.

    An analogy is this.

    Orange juice is Orange juice, add vodka to this and its a screwdriver.

    Can you describe this as Orange juice anymore? Not really something has been added to it and it's no longer the same product.

    Do you get it now?

    I stated way back in this thread, they are guilty of either misnaming or misrepresenting the product.

    But whatever way round you look at it, I'll still not use it because it voids any guarantee offered by the major material manufacturers.

    BAL APD is a wholly acrylic based primer it is not based, nor are any of it's components composed of PVA, it soaks into the surface of the substrate rather than sit on top of it and provides a chemical barrier that stops chemical reactions as well as draw.

    But obviously you know better than BAL or Ardex on this point and feel a PVA water based sealer is far superior to any of the specialist acrylic products produced specifically for the job.

    I think Mudster already said that he was going to believe what he wanted to, and he was noble enough to suggest that you do the same joe.

    As for writing words that have no meaning, it would seem that you're using a different dictionary to the rest of us - what Mudster wrote makes perfect sense. Whether it's all true is another matter, but it has the air of immense credibility about it - something that your words singularly and consistently lack.

    I've assumed in my last post that you understand the difference between a slurry primer and a standard primer, this might be where your getting confused.

    Ive asked you this in the past mudster and you never answered,what did they use before bal was invented. I was using pva,sand and cement mixed to a slurry years ago for loads of different type of jobs and it never failed and the blockes who taught me were using the same technice, i agree it becomes like sbr but it still does the job.

    If he hasn't tested the product he is in no postion to judge.

    I have tested it and it does what it says on the label.

    Ergo, his words mean nothing.

    I've never drunk PVA either but I don't need to try it to know it's not very nice.

    Will we resort to blowing rasberries soon?

    I just stick to the facts.

    If two people were to do a book review and one of them hadn't read the book or even seen the front cover, whilst the other had read it - which review would you take seriously?

    Or in a court situation would you be saying "Well M'lud, I didn't actually see what happened but I heard something similar happened in a different place ........."

    C'mon you'd be laughed out of court.

    You're obviously happy with your choice of primer, and as I've already mentioned, your most welcome to use it, I disagree with that choice for reasons previously stated.

    Lets just put that aside for one moment and consider this:-

    The manufacturer makes a product for use as a primer, if you use that primer you get all the guarantees offered by that manufacturer.

    You can choose to use an alternative that you thinks works and have used succesfully, the price differnece is negligeable if none at all, but by using this product you negate all guarantees available.

    Whether or not you agree or disagree with my beliefs or explanation, the above situation is a no brainer to anyone with a modicum of common sense.

    You use what you like. You've tried it and tested it, but don't expect people to take you seriously when you pass judgement on a product that you haven't even seen, let alone used. (and the other products are PVA based anyway)

    Step back a moment and take stock of your last statement.

    I have not tired the product you are so fond of, because I have no reason to as clearly previously stated.

    You then follow this with an enourmuos generalisation that all other products are based on PVA, and you accuse me of spouting nonsense?

    On what foundation is that gem based on?

    Where did I say that?

    You use what you like - but it doesn't follow that everything else is rubbish.

    Mudster - I didn't intend to divert attention away from your points, which are valid and very clearly explained.

    However, you're up against it with trying to get joe-90 to listen to any rational argument - many have tried and all have failed. He sees this as a kind of victory, presumably because his goal is to disagree so relentlessly and dogmatically that everyone eventually passes out from sheer boredom. I admire your staying power on this one.
