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..

Bal PTB allows a 25mm bed if required...Gaz

yep ....that was what was concerning me really, as I cant use slc over the mats ....just need to be very diligent ! lol ....thanks again

from 2mm to 25mm, pourable and solid bed...

Ah right ! ...cheers

Check this site for soverign Sovereign Internet will give some guidence

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

I've used over ufh and had no problems, Love the stuff. Put some sbr with the mix and your'll have no probs

Thanks - I was wondering about that too ....doesn't mention it on their data sheet either ....glad you confirmed though .....what ratio would you recommend ?

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

yeah, I noticed ....I've been using it for bonding ....stickytastic

will def use it in the addy then ....it'll help me sleep a bit better

thanks again
