Hi all, i'm new on here and could do with some advice.I've laid 15m2 of Devimat onto 10mm Marmox insulation boards which were addy'd over existing tiled floor.Need to know if 1 part cempolatex is up to the job of covering the ufh before tiling,as customer has supplied the gear.Any help will be much appreciated.

Doesnt look like it
Cementone Cempolatex - Latex modified self-levelling sub-floor compound

Ahhhh if you read this it seems it is ok
Cementone Cempolay - Self levelling compound

Hi and welcome..

For ufh I'd go for the 2 part Cementone Cempolatex (2 Pack) - A latex sub-floor levelling compound for smoothing uneven internal floors

Actually its very confusing....it says t use cempolatex but does not say if its single part or 2 part version. So I would say No, use the 2 part as that clearly states for UFH.

hello and thanks for the quick response.There's 8 bags of the stuff sitting on the job which are un-returnable, have an idea of mixing with a pint of sbr which is latex based, maybe suitable?

Don't add anything to the mix that you aren't supposed to!!!!

I wouldnt do that. if it fails it will be down to you. If client bought it , its not your problem. Tell them its no good.
