Ditra & Rapid Set?

[beanz]

hardiebacker don't recommend their boards over concrete floors

I was thinking about it after I posted, and it wouldn't have solved the de-coupling problem anyway.. Just grasping at straws really, trying to think of a way to do it where I don't lose half a day.. I'm too slow as it is, so losing half a day isn't a good look lol!

I've used both Glue & RS flexi , don't mind either ........ so long as I'm not the bloke knocking up the RS all the time :0). Glues cool for just pouring straight out of the tub , just don't get it on ur hands and work as clean as poss.

I've never had any problems with working setting out etc on newly laid Ditra, in fact the Schluter Instruction PDF says you can fix tiles straight onto newly laid Ditra.
I often lay the Ditra then set out and get the tiles in ready to fix the next day.
But as the guys say above, Standard Set adhesive doesn't feel right (fine for fixing tiles to Ditra), so i also use rapid set, but leave overnight, as lifting tiles can lift the matting.

Well, the builder im working for didn't supply Ditra, but it looks like the same sort of thing. More green than orange, if that rings any bells with anyone..? Hard work trying to get the matting flat with a trowel. Gave myself a blister and everything!?! lol

durabase? and maby you using wrong tool for matting? :lol:

I use a special heavy plastic float for Ditra/ Dural to remove any trapped air, you can buy a roller similar to the ones vinyl layers use. I always use rapid set and never walk on it until has gone off, unless I have to, then I use ply to spread the weight.

I have noticed in the past if you walk on the mat whilst adhesive is still soft, it can leave footprints/ indentations, not so bad if you are using large format tiles with deep notched trowel, not so good if you are laying small geometric tiles with a smaller notched trowel.

I'm very light on my feet though, i'm a princess.
Not a fan of Dural if i'm honest, just doesn't feel as good as Ditra.

I don't like using durabase /dural either. Not as flexible as ditra and can ditra as cheap as dural. I always use a 50kg vinyl roller .
iam same as most who don't like to lay tiles same day,although as bugs says, schluter say you can.

Nothing like Ditra imo.
