another fact i found -out ,was that product producers in the main are only concerned with the sub straights there product is fit for use on!! NOT WHAT MAY BE USED ON TOP OF THERE PRODUCT !! surely more research should be done by material makers in both sides as there could be a list of what not to use as well.......
Another FACT??? Sorry to be blunt but That is complete rubbish dave. It is not a fact, it is not even accurate.I have spent ten years talking to manufacturers about products to go over gyvlon screeds. I cannot force anyone to listen to me or my company. At the end of the day Gyvlon is suitable to accept ay floor coverings currently available in the uk market. And if it is dealt with correctly there is no reason to expect any issues. It is not up to us to test other people's products for them to ensure compatibility or robustness. That is their job. We will and have in the past done such tests and will continue to do somfor our own knowledge but I would expect to be paid for such advice and testing were it to be done for commercial purposes. Manufacturers have their own test facilities so would not want to pay us for workmthey can do themselves. After all do you test the tiles that you lay for the tile manufacturer to make sure they will work, do you test the adhesives to make sure they are compatible with the tiles. I think not. And if you did you too wold want paying for the work.
There is a list of manufacturers who have systems available for use on Gyvlon Screeds on the Gyvlon website. These companies have all tested their systems on our screeds. New systmes are being developed and tested by manufacturers all the time. I can't see what more we would be legitimately ale to do.
One thing i do notice in the flooring community is heavy Brand Loyalty. Nothing wrong with that unless the brand you use does not have a material or system which works and can be demonstrated to work repeatedly and consistently. If tilers (generally) were more flexible in their approach to materials suppliers and rather than choosing the one they always use they went for the one that worked best then perhaps many of the perceived issues would disappear. Just like they did in France when recommending just gypsum adhesives became more the norm rather than the exception. Many of the tilers I have spoken to have taken a more pragmatic approach to tiling these screeds and have changed suppliers. This has reduced the issues they perceive very significantly.
Really pees me off when people say only the screeders benefit. That is complete tosh as well. I have listed some of the benefits earlier. Of course the screeders benefit. That is why they are in business. Who wants bad knees, elbows, back, neck etc etc from being on their hands and knees all day in bad conditions laying sand cement. stone age Screeding is not for me regardless of how good or bad I was at it. The industry recognises he impact of these materials on the human frame and is beginning to move away from the. There are massive benefits to all sorts of people. Ok as a tiler you might have to wait a little longer to get on with tiling. Why does that actually matter in the general scheme of things. Tthe environment wins, the client wins, the screeder wins, the tiler waits a bit longer but generally has a much flatter and predictable floor to tile on to so he wins as well. What more do you guys want??!
I began this thread in a bid to help and with the exception of a few sensible comments it turned into a rant about flowing screeds. A rant which does not even have any basis in fact.......water sensitive....what the heck does that mean. If you get water on gyvlon it gets wet. If you get water on sand cement it gets wet....what's the difference there. Pile of crap.....what sort of scientific analysis is that??!! America rejected these screeds, what rubbish. They have only just begun to use them and they are only available in a fraction of the country. Where they are available they are used widely and gaining ground against other methods.....bear in mind the screed make tin America is relatively small anyway. Risddled with issues....if this were the case why have they continued to sell well throughout the uk and Ireland as well as western europe for well over fifty years.
Please guys if you are going to argue do so with qualification and accuracy not with hearsay and gossip.
End of rant.....awaits the backlash.....
