decoupler matting

[kevinz3]

hi
anyone give me some info on the dural decoupler or tile master matting , question re dural i know the tile masters anhydrite adhesive does have to be used below on the calcium sulphate and then can a flexible cement based adhesive be used on top of the matting or will it leach through and cause a reaction ?

 

[Dave]

It won't leach on the dural ci , not seen the tilemaster matting , so cannot advise on that..

stick the matting down with anhyfix after removing laitance and priming just a tip add a little extra water to the mix this will make it flow a little easier and hold the mat easier and leave it over night to bind befor fixing then you can use any flexi addy on the top of the decoupling mat

hi guys
cheers for info , another query , i am laying nu heat lo pro upstairs , and the board is gypsum based , but the pipes on the large runs are stuck to a plastic channeling and then covered with self leveller , so then the grooved boards wit the single pipes are the gypsum based will the anhyfix stick to the parts that are covered with self level or does anhyfix have a problem contacting with cement based leveller , as it seems a bit strange having 2 materials to cover

You don't have to use anhydrite adhesive. I use a cement based one following laitance removal and priming.

Which question are you replying too?

TM Anhyfix to fix either the dural CI++ matting or TM Anti Fracture Mat (if not used the TM Anti Fracture mat, you'll find it perfoms exactly the same as the Bal mat.) I would use/advise TM Setaflex ontop of mat.

ok thanks for info again , just a last one , do you know if anhyfix if it contacts cement based adhesive it will like calcium screed have a reaction

I did read that neither dural or schluter guarantee their mats stuck down with gypsum adhesive ..

Thoughts on this ?

In the first post he says ' i know the tile masters anhydrite adhesive does have to be used below on the calcium sulphate'
I was just saying it doesn't have to be.

Not to my knowledge Dave, will get a response from Dural UK and report back....

or you could just use the one tilemaster have now

 

[Lee@emctiles]

Ok, received this from Dural Uk

"The CI++ matting would work with the Gypsum adhesive, as all you are trying to achieve with our matting is to embed the fibres of the fleece layer into the adhesive.
The critical part is achieving the bond of the adhesive to the subfloor."

Cheers Lee , I'll ask the question with schluter when I meet up with the rep in June
