Building up floor level by 15mm

[sinewave]

I need to level a concrete floor with an adjacent kitchen floor so the tile run is a smooth transition.

Using self level is too expensive so was wondering whether using 10mm Marmox or Hardibacker sheets would be a better bet?


Would any further mechanical fixing be needed or is the tile adhesive on it's own OK.

Tiles will be slate

Hello and welcome..


On a solid substrate like that.. adhesive alone will be fine to hold the boards..

There are cheaper makes than marmox and just as good.

This comp will help you no probs>> Underfloor Heating | Floor Insulation | Uheat

Thanks for the quick replies guys.

Yes both floors are concrete, one's a utility room and the others a kitchen.

Utility floor screed level is about 15mm lower than the kitchen so I just need the cheapest option really to level the two floors together.


Dave, you mention cheaper options than Marmox?

Yes.. if you click the link above then you can get boards just as good but for a better price... tell them you are a tilers forum member.
