decoupling

Hi everyone! Ive got on here as I am a non tiler, but we are currently about to put down 66sqm of bottcino marble flooring, we are nearing the end of a big renovation. Our builder has installed a 50mm screed over wet ufh. We put it down middle of Dec and have been using the heating as we are...

Hi Guys, I'm after a little advice ? I'm just in the process of pricing the following job, the spec is 600x600 callibrated slate tiles on a split substrate (sand and cement screed/chipboard). The screed has pipework in it and the chipboard will have polypipe system overlay on it (approx 30 sq...

I have a 5 x 5m new extension floor to tile. The floor is sand and cement screed laid 4 weeks ago with under floor heating. The UFH has been commissioned and is on, slowly increasing the heat to warm the screed. My question is whether I will need to fix a decoupling membrane (eg Ditra mat)...

HiI am tiling the floor of a wet room/bathroom with 457x305x10mm Limestone. The base is currently 18mm chipboard (screwed down) on 1st floor joists. The area is T-shaped - 3.4 x 1.8m with a 0.6 x 1.8 spine running between the bath and 1500x1500 Fundo Wedi tray. This tray is recessed to the...

Hello folks, A quick question if I may. I'm a relatively experienced DIY'er and I'm just about to redo my ensuite bathroom. In it I have a shower enclosure (by which I mean three tiled walls and a glazed shower door over a tray) that is about 800mm x 800mm. I am planning to strip it right...

Hi All, I'm a self builder and as always I'm trying to seperate the wheat from the chaff. I have been given a price for 50mm hemihydrate screed which is to be laid on 175mm xtratherm. Originally our engineer specified 150mm insulation with a traditional 75mm screed. We are using UFH. I would...

can you lay a de coupling membrane ontop of hardibacker? im laying trav tiles in a kitchen with ufh, just wondering if this is ok cheers

Seeing some of the recent comments about laying UFH onto ply flooring & use of decoup mats I thought I'd ask a few of my own questions... I'm planning the re-fit of our en-suite. It's approx 2mx2m and we're going to tile the floor and walls with 30x60 porcelain. We've taken a liking to these...

after overboarding t&g with 18mm ply then applying schluter ditra,does the adhesive have tp be flexi? even though the decoupler allows for movement? also other than ditra where can i find info on other tanking products?...cheers!:thumbsup:

Hi, I'm about to have a bathroom floor done, its been overboarded with thick marine ply, planning to use large format tiles with thin grout lines, should I use a decoupling mat? Rob

Never used membranes as i only do smallish domestic jobs like bathrooms or kitchen floors and have up to now have only layed ceramics and porcelain onto 12 to 15mm ply depending on floor using keraflex and flexable grout, so far so good. Floors are always solid and screwed to death to ensure no...

I'm currently pricing a job 60sq. mtrs. 600/440 porcelain over ufh under screed. As I've never fixed membrane and this is a substantial area I'm unsure of how long it takes and would appreciate a rough guide price for labour. Alternatively some idea of time to fix 60 sq.mtrs in a reasonably...

Hi all, this is a job I have been doing for the last two weeks, which started as a repair including 9 tiles, but because the floor was laid so badly this ended up being 50 odd tiles, after removing the originals, with 16 of the lifted tiles having to have 5mm of screed ground up and dural ci...

A client wanted a decoupling membrane as she has 15mm stone tiles on the floors and 10mm basalt(I think) on the walls.Do walls move like floors and if so can ditra matting be used on walls?Because I have only ever used it on floors!And if it cant what is the best substrate for walls,,because I...

Hello experienced craftsmen, I need a little advice. I am in the process of building a bathroom which is constructed so far as follows. The floor is normal chipboard floor which has been overlaid with 18mm wbp ply screwed at 300mm or less centers, all walls within the shower area are Wedi on...

One of my worst nightmares ever was a few years ago where the architect was adament that this was to be to be laid down. I had a feeling of impending doom which returned to me two years later when the client called me back in as the stone was breaking up. It turned into a war zone, with the...

Hi all, this is about my third thread today but i have a few questions. I have never used a decoupling membrane before but i think i need to on this job, what do you guys think. Its 33m2 floor using 600x600 porcelain tiles. The customer is a mate of mine who's been in building trade for a few...

Hi all, Just wanted to see what people think about using a decoupling membrane with Travertine on concrete floors that aren't heated. Obviously for piece of mind ( belts & braces ) , but when could you perhaps not use it & when should you definately use it on concrete. Your thought as...

I see alot of mention of decoupling membranes on here (Never heard about them until this site). I know very little about them and wondered if someone could explain alittle about them :)
