Flooring - Is this Daft ?

[Spinny]

So now my flooring people say they can't fit in levelling my suspended floor before my kitchen & utility fit !

They are now proposing to finish levelling only the open plan kitchen room (concrete floor) and stop the top coat of levelling compound a few inches onto the suspended floor with some mesh under across the join. Then return later (after the kitchen fit) to screw and prep the suspended floor and put the levelling compound down the hall and into the utility.

 

Is this sensible or wise ? Should I call off the kitchen fit (again) ?

 

The suspended floor is omnie torfloor2 underfloor heating system with 12mm ply top board. The kitchen company obviously want to fit kitchen and utility together, and obviously don't want to rearrange their kitchen fit. They are telling me it will be fine for them to fit the utility onto the raw omnie ply and then have the flooring people put the levelling compound on afterwards (to be followed by LVT) so that it runs around the bottom of the panels that go down to floor level. It is just a 2m run - washing machine bay, dryer bay, sink cupboard, and wall cupboard.

 

Is this a sensible approach, or just trades wanting to find any botch they can to (1) fail to deliver my levelled floor on time and (b) install the utility onto a floor that isn't fully prepped ?

 

Cons: 

1/ Will there be issues where the final levelling compound is done in two pours - one for kitchen - another later for hall and utility. e.g. cracking, step or ridge in levels ?

2/ Is it wise to not have leveller under the utility end/divider panels/legs - possible route to future water spills/leaks reaching the plywood ? Damage to bottom of panels from the wet leveller ? (they tell me bottom of panels are sealed). PITA if the utility cabinetry was changed in the future as there would be strips of missing floor leveller and missing spots under the legs.

3/ Not having the final floor level in the utility when they fit the cabinetry in there.

4/ Delay to floor finishing in hall/utility

 

Pros

1/ making the flooring people do the whole job in a rush could jeopardise a good floor finish

2/ More time and space to screw and fill the suspended floor boards properly

 

Should I make the kitchen people come back to fit the utility later and separately from the kitchen - no doubt at extra cost and with great resistance from them ?

Why plywood and not ‘no more ply’ / other board type?

[Spinny]

We chose Omnie TorFloor2 back in 2023 and had the makeup of 22mm routed chipboard, with 12mm routed plywood coverboard. I think we had the plywood cover board because (1) it was 12mm and helped us get the floor up to the level of the concrete which the builder had laid higher than planned and (2) the flooring people normally lay plywood as the basis for laying LVT. We had a debate about the omnie plywood topboard not being SP101 but the flooring company said they could LVT onto it in the end.

 

I see Omnie have now been bought by NuHeat and the Omnie dedicated website has disappeared.
