Have you any feedback on KeraKoll adhesives ?

Yes - I had a meeting with them about 3 weeks ago. They came and did a presentation to our sales meeting. I have now seen H40 Ideal used on three anhydrite installations and know of several others where it has apparently been used. It seems a good product although I look from a screed perspective not a tilers. It is made from some voodoo chemicals which resist the formation of ettringite (I think it is just sulphate resistant Portland cement) They insist that it can be used direct to anhydrite without the need for a primer. My colleagues and I would not dream of calling their technical expertise into question as they come from a pretty secure pedigree and have tested the stuff to destruction in Italy. Tiling to absorbant screeds of any type without a primer gives me palpitations though.
In one of the installations it was installed with a Epoxy DPM/primer because patches of the screed were still slightly damp (82% RH). In the other 2 it has been used with a standard acrylic primer. All 3 have been on wet underfloor heating and I have written the specs for all three screeds so at least I know they have been designed right. No feedback from the jobs since installation but I guess I would only hear anything if they went wrong so sounds good at the moment.
I have yet to see any installations in the UK without a primer but it will no doubt happen. Price wise it seemed to stack up. Certainly the one on the epoxy was done by a big tiling outfit who have good buying power and they told me it was actually cheaper than what they were currently using (they were using Bal) I spoke to the tilers in all three installations. Two were very impressed and had no critisisms. The other said his only criticism was he was used to using rapid set and this one is standard set. When I said this to kerakoll they said they would look at the demand and possibily develop a rapid set version. I guess it might set much more rapidly on an unprimed screed cos of absorption. The jury is still out for me on the primer thing but I do put them forward now to my customers as one of several options. I still prefer Gypsum on Gypsum though for obvious reasons justv wish the gypsum based addys were more easily available like in France and Germany. Was talking to Weber the other day as well. They have a gypsum based addy available but it is not stocked in the UK. I am trying to persuade them to bring some in.

latexing is a art in getting it right and none are truely self levelling , spike roller and straight edges and a understanding of the products and how they work , mir-plan and weber fibre latex are very good products its just a shame ardex-bal are lagging behind

Been using Webbers new SLC. Lovely stuff, but even though they say it sets in 3 hrs, you can't place tiles on it for 12 hrs, only light traffic after 3 hrs.

Just bumping some of the older popular (sometimes not so popular) threads. Probably wont be current discussion these days but I just need to do it. So just ignore the thread if it's not current for you.
