Plumber has put this water unfloor heating system down and left it to us to sort out. What's best way to prep this. Its 25 mm lower than the 3 doorways where marble is fitted and they want the lvt flush to that. Sent from my SM-G998B using Tapatalk
Could you cement board over it? Can’t see the pics through Tapatalk Sent from my iPhone using Tapatalk
Either cement board and screed or just screed, if you go with just screed, i normally do a coat just to fill in all the holes first, then a thick coat, as I've found if you just do a thick coat first, it can sometimes run underneath the insulation board and cause it to lift
I thought about cement boards but there are various places where there's ridges and undulations. Is it possible to screed over as the foil parts are polystyrene Sent from my SM-G998B using Tapatalk
Could you put tile adhesive under the cement board to level it? You probably can screed over it but it would have to be deep. Maybe ask the board manufacturer if they have a screed manufacturer they guarantee over it. Sent from my iPhone using Tapatalk
Just seen pics. Surely you can’t fit lvt over that? You probably need a 25mm liquid screed over it? Sent from my iPhone using Tapatalk
Timber subfloor tho. I would defo speak to the manufacturer of that ufh system Sent from my iPhone using Tapatalk
I think it's prowarm injoist foil system. Something like that anyway Sent from my SM-G998B using Tapatalk
Just looked on their website, it looks like that system is only designed to go between joists or battens, with a solid subfloor over top, so the insulation doesn't actually support any flooring, might be best to check with the manufacturer, to see if it will. Another possible option could be to cut out the insulation and fit battens straight to the floor underneath, then board on the battens, although it would probably be a pain in the arse to do
