[lol knowles]

hi i am about to lay 600x600 mirror fleck quartz tiles on to my kitchen floor i am laying 6mm hardibacker boards on to floor board as floor is sound i am fitting 2 x 800 loose wire warmup kits then will use rapid flex adheasive , the tiles were brought from marblemosaics who say they are 93% quartz and are fine ,warmup say it should be ok so just checking any advise or should this be ok

i would use self leveller to cover the wires before tiling!
you will need seal these before and after grouting,try and keep to a 3/4mm grout line,use black grout or glitter grout! they all need wet cut also

hi david i was thinking about a flexible leveling compound to hide the wire also to help make tiling easy not sure about the level compound on hardibacker though never done that before

[doug boardley]

what made you choose hardibacker rather than insulation boards Lol?

[lol knowles]

had a job go bad with faulty backer boards that delaminated aparently so i put in a claim and they could not give me money but gave me a palet of hardibacker worth £1000 so i,ve got tons of it

[doug boardley]

just thinking that heat will transfer through your hardi to your subfloor, losing you money.

Not the first time I've heard that about backer boards

[lol knowles]

i thought it transfers off hardiback ok. tiled my last bathroom with padovas on hardiback no level compound and it was fine i can exchange the boards if you think its a better way i just trust the tiles to stick to hardiback only ever used insulation boards about 3 times

Are these the resin type tile that should'nt have ufh because they can bow/curl at the edges
