Any one use this brand "kerakoll",I tried a bag of their marble adhesive and thought it was quite good to use

never used it Gary.i'm starting a nice marble floor tomorrow and have keraquick white in the back of van.

Yes.. they do a gypsum based adhesive as well...

is kerakoll a cement based addy, for use on a gypsum substrate?

Kerakoll is a brand of adhesives doug...they make loads of different types....Gypsum based is one of them...no priming required for use on gypsum substrates as it is gypsum..

Its nice stuff to use

Just to avoid confusion KeraKoll is not a Mapei product as it sounds !

cheers Dave, I thought I'd heard about a "crossover" addy, for want of a better expression, that bridged the need to prime a cement addy on an anhydrite substrate

Don't think so. Thought it was a while ago but the H40 Ideal is a sulphate resistant cement based addy. Unless they holding out on me of course. Sorry If I got it wrong. I am human after all.

It's not cement based doug...it is a gypsum friendly based adhesive..

H40 ideal is the one i think..

Seen it used a few times now.

With cement Addy you are better to use Epoxy Primer (Tack free ideally) I have yet to see an ettrigite failure with this system. Uncoupling works as well but I have been talking to other manufacturers and all sorts of gypsum based addys are crawling out of the European woodwork recently. Uzin is the latest. Weber have one, apparently PCI have one, Benfer have one, Forbo have one - frustrating thing is they don't sell them in the UK. Only one in the UK which is easy to get hold of is Creative IMpressions but they based in Preston and whilst they deal direct it's not the same as picking it up at your local tile shop. I guess if the tilers began to demand it it might happen. I'll keep pushing - we don't change very fast in the UK and anhydrites have only been about for 20 odd years after all.

I did post a data sheet a while back in the thread calcium sulphide screeds but I can't figure out how to attach it to this one and it wont let me post it again.

Kerakoll.com

Here is the link to the website data sheet though. I have not seen the Spanish version so they may have a product I don't know about but I am certain that the H40 Ideal in the UK is sulphate resistant cement based. I met with their Technical Manager ad one of their sales team and they are very confident about the primer thing but I have yet to be convinced. Obviously if it can be used without a primer that is a cost advantage but it is so completely alien to me not to recomend a primer and I can see so many issues with absorbant surfaces such as screeds.

Sorry Me no speeka da italiano so good

H40 Rapid and Top Latex is good stuff, and their Fugabella grouts are nice enough to use. Not too keen on their wall adhesive, can't remember the name of it, Tenax I think, but it reminds me of bucket adhesive. Sticks well, just won't let you hang tiles.
