decoupling membrane

Hi all, Was talking with an adhesive rep yesterday and he was demonstrating some slc.. his demo was over decoupling membrane which raised the question.. Do you level over the decoupling membrane or under it? If you had under tile heating for example would you put this on the levelled (wood lets...

Hi all. We are having a tiling job done with dural matting over plywood. We were supplied with the adhesive in picture attached. Is this considered unmodified thinset? Is this OK to use both under and over the matting? -Please see post 4 for image.

I think I know the answer but I will ask anyway .. I have a kitchen that is to be in an extension. Part of the original slab is staying, the rest ( 30 m2 worth ) is being wet underfloor heated and traditional sand and cement screed. I have advised the customer we will either have to line a...

Evening all, ive measured up 75 metres of suspended chipboard flooring split into four rooms at a property last night.ive allways used hardi to overboard wooden substrates but was wandering if a decoupling membrane could be used? Theres a good deal on at ctd and thought this way could possibly...

I am aware of the limited choices of decoupling membranes available and the colours which they come in (most are manufacturer specific). What would be your preferred colour of membrane and why? I actually quite like working with orange coloured decouplers, but if I could choose another colour...

Hi I am laying 14 sqm of 12-15mm sandstone tiles onto a concrete 1930's floor. DPM is unknown - but damp does not appear to be an issue- i don't really want to dig up concrete and lay a dpm. It was previosuly sealed with bitumen which was about 15mm thick. I wasn't sure of its purpose as a self...

Ive a job to look at friday eve to tile in 600 polished porcs(15 m2) .My concern is that roughly half the floor is existing concrete screed layed on top of insulation board,and the other half is fresh(2 month) screed over insulation.Would a decoupling membrane and flexi addi suffice for any...

Hi all, Anyone ever come across a decoupling membrane called Decomat Pro and any opinions of it? It's a blue plastic circle pattern with a bluey-white fleece on the top and bottom. Cheers

I am pricing a 100m+ limestone floor on top of wet UFH set in a concrete screed. I have used Ditra in the past but wondered if any of you have other preferences and why? A decoupling membrane has been specified but nothing has been mentioned about which one. So, which one to use? Ditra, Dural...

I'm sure the answer is here somewhere already and my apologies for asking this. I am, what I'd like to describe as, a competent DIYer and am now intending to create a wetroom in an existing first floor bathroom. It's a relatively small room, say about 2.5m x 2.5m. I want the smallest possible...

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...

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)...

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...

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...

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 :)
