6mm ply and warm-up underfloor heating-best flexi tile adhesive??

[Hayden Goy]

Hi all,

Which is the best Tile adhesive to get?? i've have a concrete floor with a 6mm ply base which ive used evo to stick it down with. I've got warm-up underfloor cable to go onto this and was wondering which is the best tile adhesive or grout to buy??

thats all

Why put a 6mm ply on a concrete/screed floor

You are at a stage where you can really improve your warmup time. Speak with Aaron at U-heat and get the ply up and lay insulation board instead.
Then use a SLC suiteble for UFH over the mat or wire and use a flexible addy your tile shop recommends for the application.

To stop the loss of heat from the underfloor heating and the 6mm insualtion boards i had was rubbish

i cannot take the ply up now its too late everything is fixed onto it and i had underfloor boards but i wasn't happy with the strength of them I only have 6m to play with.

The ply could cause you problems later on, the cold from the floor and heat may cause it to move and tile failure. Check the sponser UHeat he do's insulation boards at a very good price

If it was me id kango them up and get cement reinforced 6mm insulation boards.

Its your call but it will make a big difference.

Underfloor Heating | Floor Insulation | Uheat

the floor temp shouldn't change that much it has 100mm kingspan under-it. so its already insualted
