1st Time Tiling New Build

[AllanHarris1986]

Morning all,

I have been looking through the forum for a post which offers a similar situation to mine but failing.

I am seeking some advice from the guys with experience. This will be my first time tiling so excuse my ignorance.

I am moving into my new build house on Thursday where I am looking to tile the whole downstairs area (50m^2) with 600mm x 600mm x 10mm porcelain tiles.

The floor is concrete base with 200mm of Kingspan with floating chipboard on top.

My plan was to source 6mm Hardibacker to cover the floors and set with a flexible thinset mortar (recommendations of mortar appreciated) and screws. I have read mixed opinions about applying a decoupling membrane over the top of the hardibacker to account any lateral movement. What are peoples opinions on this based on the area of coverage and floor construction? Recommendations on brand of decoupling membrane and flexible adhesive welcome.

Would I get away with tiling straight onto the Hardibacker with flexible adhesive and no decoupling membrane?

This will be my own house so looking to put in any additional measures to prevent tiles cracking long term.

Advice is greatly appreciated.

I would advise you to get a tiler firstly !! It's not that easy .but also I would not rely on 6mm of any extra strengthening!!

You really don't want to be tiling a floating floor.This will only invite problems.

I agree !! And especially in a new build !! If it were my house , I'd take up floating floor , tank the probable concrete floor , and get it screeded or another equivalent , insulation can be added under the screed with depths you mention , and then use a decoupling membrane , then tile , using expansion joints on any area over length of 7 metres
