Is this a good solution for parquet dilemma?

[kissinger]

I’m putting parquet all through my downstairs, but I have a 3mm lip where the suspended timber floor buts up against the concrete slab in the kitchen (put in during previous extension).

I thought about simply putting down a metre of 3.6mm plywood in front of the lip and feathering it via sanding. Would that work?

Seems a lot cheaper, easier and sturdier than levelling compound.

I think it's a lot more work than shaping something cementitious in though, as you'll want to run quite a way to avoid having to do a considerable amount of sanding to smooth out any kick in the parquet ?

Over what distance should I feather it? I was hoping 60cm or so?

Is the concrete 3mm high? if so could you not grind it lower, or if its the floorboards could you remove a few rows, and replace with thinner boards, packed where needed?

 

[robinbanks]

Long as you can be bothered with, I'd say. 60cm doesn't seem unreasonable unless the parquet blocks are large.

If you end up with an obvious kick anywhere in the parquet and the adhesive you're using has some flex maybe also consider (part-)bedding the transition ones on a harder adhesive, like gripfill, that way you remove a potential movement point

You can buy a strip of hardwood to match the parquet cheaply enough.

(I think the parquet is continuing into the kitchen and has to cross this uneven boundary..)

Plywood is too thin to take the traffic and i'd say it'll wear out fast.

What about product like this ‘hardwood board’: https://www.wickes.co.uk/Non-Structural-Hardwood-Plywood-Sheet---3-6-x-606-x-1220mm/p/110514

I would say that parquet is not a good choice for the kitchen anyway.

You need at least 5.5mm plywood down on the timber sub floor.
