Hi there has anyone used the ardex K15 self levelling compound on a screeded under floor heated floor?? any good? flexible?

Also is the Ardex X7R any good for under floor heating laying porcelain tiles?
Is there anywhere which sells ardex cheaper than £45 a bag???

They are both ideal for UFH on screed. Where are you in the country?

i am in west sussex haywards heath

Ardex have main suppliers who then have Ardex permission to co-sell on their behalf, so ring a few tile shops in your area they may sub-buy.......thats the problem with Ardex and why if you don't go to a main seller the price is high!

Cheers Fred thanks for your help also someone said hampshire tile warehouse was good on ardex prices

Give them a go, if their good on prices, they have the Ardex account. My main shop I use are the areas Ardex dealer, and I get X7R for £20.00p

K15 no good for ufh.....Have you heard of Mapei fibre plan.....excellent product...

According to Ardex tech it is ok Dave!

yes my mate uses ardex K15 on UFH and swears by it he tells me!
Think as i'm using the brilliant flexible ardex X7R i might stick with ardex and use the sub floor K15 and spoke to ardex and they say its fine for ufh, no problems ever.
cheers for advise though and the tile people in hh are not the most helpful and overpriced!

Also Fred i have found that hampshire tile warehouse do Ardex X7R grey at per 22kg bag now thats good! and Ardex K15 per bag.

Hey!! sorry about that...had timber in my head somewhere...lol lol.....

On conrete/screed type subs it is ok....

It can go upto 10mm then over this use aggregate mix to strengthen...

I used to use k15 all the time but since i have used mapei fibre plan which can be used over timber as well then i have switched...fibre plan does upto 15mm in one go...not bad over timber for a single mix slc...

I have also used weber niv plus and that does 25mm in one go....there are lots of fibre enhanced levellers coming on the market now...and one i have found out today does 60mm in one bite....pjc(pete) knows which one...

Cheers Dave for that and I have used the mapei rapid set but don't find it as good as the ardex even palace chemicals £12 a bag White rapid I find is better but guess it's all down to personal pref.
