30m2 floor to tile. Any advice?

[Ollie02948]

I have a 30m2 kitchen floor to tile at end of week. The whole floor is suspended but one half is floorboards and the other chipboard. The tiles are Italian porcelain and will be either 600x600 or 300x600 depending on customers choice. It is also to include a underfloor heating mat. I'm going to prime the floor, fix marmox 12.5mm boards glued and screwed joints taped etc. mat to be fitted. Mapei ultra plan renovation screed on the top. Prime then tile. Do you think that would be fine? I will be making sure everything is deflection free. Would I be okay bridging the two substrates with marmox or would you fit a decoupling mat?

thanks ollie

What do you class as suspended.. ?

 

[Ollie02948]

Joists, floorboards and chipboard all screwed

As long as deflection is minimal , then marmox will suffice .. then slc as you say.

That's great thanks a lot for your help dave.

The joint at the change on covering ..? is this new to old or existing joists..?

 

[Ollie02948]

New to old. Kitchen has been made bigger my knocking through to garage and installation off a suspended floor to bring to existing floor height

OK.. you need to fully make sure there is zero deflection at this section , lateral expansion isn't an issue when marmox is used on deflection free substrate.

Ok I will make sure it's all fine. Thanks for quick reply.
