Minimum bed depth ??

[AllurePTS]

Hi Guys ....just about to do a kitchen floor as follows :

18mm WBP ply deck, heavy duty dpc underneath, screwed @ 300 centres with addittional 110mm spit hits through to concrete sub floor = solid !

10mm thick synthetic quartz "stone" tile

Centre area is to be fitted with UFH mats (3-4mm thick)

Problem is, there's not much to room to play with to try and keep the floor height down and avoid a step with the adjoining finshed floors .....so the question is - what would you say is the minimum depth of adhesive bed that I can (safely) get away with ??? ....using porcelflex btw

Cheers

As long as the tile has 100% coverage then thats what to aim for....not bed thickness....so the flatter the floor the easier that is to achieve..

Cheers Dave .....floor is pretty good - high spots 3-4mm only

No probs....as long as you get excellent coverage then no probs...good luck..

yeah, I read the data sheet already - doesn't mention anything about a minimum thickness over UFH mats ....I just wondered if there was any recomended standard ....as I was a bit concerned with getting full coverage while trying to maintain the thinnest bed possible ....seems not though

Thanks for the help

regards

2 water and 1 sbr but keep your tools clean that stuff sticks like no other, I've used with 10mm trowel over ufh
