    Slc or ditra mat to tile over UFH?

    Hi I asked the Wunda technical department if I can just use a Ditra mat only and not the SLC. They said the Decoupling membranes are fine to use, they just don't form part of their normal recommendations. They advise that it would be best to bond the Ditra mat down with the recommended tile...

    Porcelain SLC over old tile adhesive

    Further to my other post re our hollow tiles issue It looks like our tiler has dot and dabbed most of our floor to accommodate tiling 800x800 porcelain over an uneven floor. The gap from defrac membrane to the underside of the tiles in question is around 20mm. The membrane sits directly on our...

    SLC over Durabase CI++. Have you?

    I'm interested to know if anyone has used SLC over Durabase CI++. I know that Schulter advise against using SLC over Ditra but is it the same with Durabase CI++? Having had a look at the technical data sheets etc there is no mention unlike Schulter who state not too. I also note from comments on...

    Phil Hobson SLC Dot and Runner Method

    Hi, this is my first post here in an amazing forum where I have learned so much. I've used SLC a few times in the past but have loads of levelling to do in my 60s bungalow where the floors have dropped. I'm using Arditex Na in two layers with DPM1C in the middle. I can see why Phil Hobson is...

    Help. SLC failed under tiles.

    Hi, a few years ago I used SLC in a conservatory on to the original concrete base. I primed and followed the pack instructions and info I found on here and let it set for a few weeks I think before tiling over it (I don't rush these things) Now the tiles sound hollow in certain areas. I...

    Staplegunning UFH Stickymat to prevent it rising/floating into SLC?

    In two minds as to whether to go for UFH stickymat (followed by decoupling membrane on top) or more expensive UFH decoupler 2 in 1 system If the former, has anyone had luck preventing the stickymat from floating up into the levelling compound by staple gunning the mat itself onto the tile...

    Screed / SLC over old marleys

    Hi all, I have a room full of old asbestos marleys in good condition (apart from a few chips by carpet grippers). Can anyone recommend a screed / slc to go directly over the top of the tiles? I don't want to pull them up. Thanks

    Hi everyone, I'm looking for some advice on final floor buildup. We're installing a shower tray onto ply (with grab addy), it's 1700x800mm so should perform as a wetroom, closed on all sides apart from a bit at the end of one side to get in and out. So my question is about the rest of the floor...

Just from a bit of...

    Adesilex P4 - SLC and adhesive?

    Mapei describe this stuff as capable of being used as an adhesive and as an SLC. Wondering if anyone has done this and how did it perform for both applications? I figured it mt save me a bit of cash on materials if one product does both. (seems weird though that they do sell a couple of...
