Probably a bit of a long shot this one but has anyone on here used Deckfon Ultra 3 or 5 from Celecta as a underlay for tiling onto. If you have - what adhesive did you use to stick it to the screed and what tile adhesive did you use on top?

Not one i have heard of Alan..

I've tiled onto something very similar, if not the same. I used bal fastflex, (with the latex) Alan. Adhered really well

Do you know what type of adhesive it was stuck down with. Was it a tiling adhesive or a carpet adhesive?

Is it an acoustic layer Alan..?

it wasn't a tiling addy Alan, it looked like a type of contact adhesive

it is Dave, designed to nullify impact noise

As doug says Dave it is an acoustic layer. It says you can apply tiles and that it should be stuck down to the substrate. Got a real major issue with an installation on site cos the client cannot get the ruddy stuff to stick to the screed. He has used an acrylic primer and a pressure sensitive adhesive which does not seem to set. It is a carpet adhesive which is why I thought the thread might be a long shot.

What is it made of..?...some are stuck down with contact adhesive but also some can be stuck with an S2 adhesive..

this is the stuff

Not something i would tile on doug by the look of it.....the ones i have seen have a top layer suitable for tiling... similar to schluters Ditra-sound system.

Was waiting for someone to say not great for tiling on to. Not sure yet cos I have not been to the site to look but I too think it will be too compressible to receive rigid tiles. Will let you know when I bin on Tuesday. does any one knoe thw minimum requirement in terms of compressibleness (If there is such a word) for a floor to receive tiles? This stuff says it is 20kpa at 10% deformation.

I just know the word..minimal Alan.....i don't think it so much the compression issues but the actual bonding to it...looks like carpet underlay..

I expressed concerns myself at the time guys, but the builders (Rogers lot lol) had got the tech data sheet that said it was ideal to tile on. I was on that site 6 months and never heard of a failure while I was there
